The way in which the Union was built, geared towards the goal of freedom of trade whilst limiting as far as possible the sharing of sovereignty, cannot provide Europeans with the protection they are expecting at present. Of course, it should always be recalled that European integration brought about peace and reconciliation. And it should not be forgotten that the pacification of the continent allowed unprecedented prosperity [2]. But the Pax Europaea, for which the European Union won the Nobel Prize is not a guarantee for social peace in the face of the economic crisis, for domestic security in the face of terrorism, or for the protection of the external borders. Unsurprisingly citizens turn to their States, which however are often economically and politically weakened, because they still embody most of the Regalian functions and prerogatives of security. European integration seems therefore to be directly threatened: as a space without internal borders, it raises fears of contagion of the crises from the periphery (geographic and economic) to the heart of the Union, without being adequately equipped to rise to ensure a collective, Community wide response. The feeling of the Union's inability to defend itself, except in the monetary area, places it opposite the models of other federations and confederations, where it is on the contrary the very foundation of collective identity and of the political legitimacy of common institutions.

In this context this paper recalls the factors that have underpinned the unification of Europe to date and analyse the causes and implications of their collapse. It then seeks to identify the intellectual and practical conditions for a revival of the European project allowing it to rise to European expectations regarding the economy, security policy and the rule of law.

The collapse of the traditional unifying factors. The risk of fragmentation?

The weakening of the founding narratives. Peace, market and what next?

The features of the present European "crisis" [3] are easily identifiable: economic uncertainty, institutional weakness and the perceived lack of clear, effective, legitimate leadership, the rise of national-populist forces, turmoil south of the Mediterranean, increasing religious fundamentalism, a growing number of challenges launched by the new world disorder [4], and Europe's uncertain position in the world's new economic and geopolitical balance of power. Besides, the weakening of the narratives that legitimised European integration highlights the difficulty of reviving political ambition across the Union [5]. To understand the European crisis, the link between European integration and its founding narratives, whose influence is waning, needs to be recalled.

European integration was at first an effort of redemption after the collective suicide of two world wars and the sublimation of national political rivalries with the rejection of the logic of power which led to the stabilisation and pacification of the continent. In the process of unification the economy played a major role, particularly after the rejection of the European Community of Defence in 1954 by France which had however been at its initiative. The economy was instrumental at first: in Robert Schuman's project, "de facto solidarity" created by the internal market was meant to create joint economic interests to discourage the notion of "every man for himself" thereby helping to overcome nationalism. Under the aegis of NATO Europe's discourse also influenced the mobilising role of the Soviet threat and the "sense of history", that of the reunification of the continent. This period ended at the beginning of the 1990's with the "end of history" [6] proclaimed after the collapse of the communist bloc.

A second period had in fact started slightly before this under the impetus of Jacques Delors with the support of François Mitterrand and Helmut Kohl. After peace and unification, the idea was for prosperity and solidarity to guide European support to the project of Grand Europe. At the beginning of the 1990's after peace and reconciliation the economy became the focus of European discourse, with the Single Market - the biggest market in the world [7] - and the euro as its structuring elements.

The change of national visions

European integration has historically been the product of a combination of different factors of internal - reconciliation, pacification, democratisation, economic integration - and external unification - Cold War, the Suez Crisis, decolonisation, the fall of the Berlin Wall and the end of the USSR, reunification of Germany - together with national political rationale, with each Member State conveying interests and a specific vision of its contribution to European integration. We know the famous phrase of Zbigniew Brzezinski: "Via European integration, France is aiming for reincarnation, Germany redemption." [8]. For its part the UK and the countries in the North of Europe (which show some reservations with regard to European integration) traditionally target the "optimisation" of their national interests in a "utilitarian" rationale of "costs and benefits" [9]. For their part the countries of Southern as well as those in Central and Eastern Europe have followed a rationale of "sublimation", i.e. the rapid transformation from one political (dictatorial) and economic (shortage economy) state to another ((liberal democracy and market economy). In spite of the heterogeneous nature of this political rationale the European Union is the result of a meeting point and negotiated compromise of different viewpoints. However for the last few years now these national views have evolved.

Is Germany's rationale still one of redemption? Some observers say that Germany "is no longer European" [10]; would it not be more exact to say that it has "normalised"? [11] Germany reunified and is now the continent leading economic power, it is the centre of a widened Union. These developments comprise a real change for the dynamics of integration that must be taken into account. At the same time German Chancellor Angela Merkel, during the euro zone crisis, whilst defending the interests of German taxpayers, admitted that the euro's failure would be that of Europe and that there was still congruence therefore between national interests and those of Europe. Moreover, although Germany's economic results facilitate the assertion of its model and of its national interests in a completely uninhibited manner, the rationale of redemption still seems to be at work in the diplomatic and military spheres, as shown by the hesitation then divergence between the government and the German public opinion regarding military intervention in Syria and even in the management of the refugee crisis [12].

France for its part has blown hot and cold for a long time. It was behind ambitious projects of integration and has also often been extremely reticent about these very same projects [13]: the European Community of Defence in 1954, the Empty Chair crisis in 1965, the European Constitution in 2005 and the most recent example - European economic governance. Generally French diplomacy prefers the intergovernmental method. Within public opinion there is reticence about the federal idea of European democracy in that this means the possibility of "French ideas" (interventionist economic policy, a strong civil service, mistrust with regard to liberalism, Social Europe and also Powerful Europe) being in the minority in the European debate, especially in a Union extended to 28 countries [14]. This was one of the lessons of the French "no" to the European Constitution in 2005. Over the last 10 years the situation in France has weakened further from the political, economic and social point of view, which has influenced the rise of Euroscepticism both in the political class and also amongst French public opinion [15]. In a context like this it seems that France no longer believes in its reincarnation within an enlarged, free-market Union, in which it no longer identifies and seems to be seeking a new European narrative [16].

Is the UK, which is tempted by the "Brexit" (British Exit), still trying to optimise its national interests within the Union [17]? Two apparently contradictory temptations may swell the ranks of those supporting the "leave" camp. The first of these is isolationism. This is being fed by sovereignism and the fear of immigration, which might grow with the difficulty to find a solution to the refugee crisis in Europe in a context in which the supporters of the "Brexit" foment confusion between free internal movement and external immigration. The second temptation is that of global free trade and becoming an offshore financial centre. Underpinned by the memory of the Empire, by a striving Commonwealth, and also by the desire to protect the status of leading financial market, this vision proclaims the UK's global vocation that EU regulatory constraints is perceived to impede. Both of these temptations, isolationist and globalist, are founded on a more emotional, identitarian rationale than one which is purely utilitarian. And their contradictions are but apparent: whilst the government aims to participate in the free movement of goods, services and capital, but not in that of people, the supporters of the "leave" vote dream of turning the UK into a "big Switzerland", open to foreign capital and competitive, but closed to immigration and exempted from unwanted European rules. In the "stay" camp emotional rationale also mixes with that of interests. Its supporters also play on the fear of the unknown and the prospect of a fragmentation of the UK if an exit of the Union led to the independence of Scotland. The result of the referendum is of course extremely difficult to predict. One thing is certain though: a Brexit would precipitate the UK into the unknown and into extended negotiations over the terms of separation and its future relations with the Union. Brexit would also be bad for the Union: beyond the loss in terms of economic, political and strategic influence caused by the UK's exit, it would be a symbol of disunion, in a context in which the Union and its States need unity and cohesion in order to rise to the challenge of the many crises affecting them. It would instil fear of a possible "dis-integration" [18] of an unrivalled regional experiment in the world and would boost the europhobic discourse of certain national political forces: in the Netherlands for instance, some popular newspapers have already raised the prospect of a referendum on the Netherlands' membership of the Union [19]. Although the Brexit is not necessarily probable we must foresee its possibility and think about the various scenario that might result from the outcome [20]. This is the necessary condition to overcome the uncertainty that hangs over the outcome of this process.

The economy is no longer a unifying factor

Although the markets are no longer forecasting the collapse of the euro zone, due to the action taken by Member States and the European Central Bank, its situation is still worrying. From an economic point of view it is clear that the crisis and its consequences, both economic/financial and social, have to be taken seriously, particularly the decrease in investments and its implications for growth potential, high unemployment, notably amongst the young people in some countries, the decline in purchasing power, an increase in poverty and rising inequalities. From a political point of view, the crisis has widened the North/South divide of Europe [22], which is visible both in terms of expectations and representation. Germany and with it, Northern Europe, expect the States in the South to show their ability to grow without accumulating public and private debt and to undertake structural reforms tackling in particular tax evasion, corruption and corporatism. For their part the countries of Southern Europe that have been weakened by the debt crisis, hope for stronger financial solidarity on the part of their partners in exchange for their commitment to greater responsibility, notably in terms of managing government finance and undertaking reforms.

Of course with the crisis, fundamental debates over the future of European integration have been raised and work to complete the euro zone has been undertaken. In order to recover their sovereignty in the face of the markets and therefore the ability to decide over their future Member States, notably those in the euro zone, have understood that they have to consolidate the Economic and Monetary Union. Financial solidarity mechanisms have been introduced and the European Stability Mechanism (ESM) has entered into force; stricter common rules have been adopted in terms of the budget and economic governance mechanisms have been strengthened ("six-pack", "the budgetary pack", "two-pack") ; and the Banking Union project has moved forward, conferring the tasks of supervising banks upon the ECB, as well as creating a joint mechanism for the resolution of banking crises, ahead of the possible creation of a single deposit guarantee system.

However there is still disagreement between Member States regarding economic, financial and fiscal union, notably about European interference in national decisions and the timeliness of increased solidarity (for example a credible, backstop for the Single Resolution Fund for bank crises, a single deposit guarantee system and a euro zone budget taking the shape of an investment capacity or common employment insurance). In addition to this the challenge made to the legitimacy of European decisions demands progress in terms of Political Union, which is only moving along at a snail's pace [23]. But in the present political climate, marked by rising populism, as well as extremist, anti-European parties, most heads of State and government deem that this context is politically unfavourable to an ambitious reform, considered to be politically risky, of the Union and the euro zone.

This is especially so since, although the danger of fragmentation has been overcome in the euro zone, we cannot be sure that the economy will continue to play a unifying role that it had been assigned since the start of European integration. This rationale did in fact collapse with the financial and economic crisis and its social consequences. Moreover, the euro zone crisis highlighted the deep economic and political divergence that has appeared over the last few years between the Member States, notably between Germany and France. One of the lessons learnt in the Greek crisis and from the risk of a "Grexit" has been that the economy is no longer a unifying factor but may divide, becoming an area for the expression of national political power struggles. The dynamic of economic integration, although necessary, does not necessarily go hand in hand with an increase in cooperation between Member States. Likewise, economic interdependence does go hand in hand with a return of power struggles and of nationalist passions at Europe and even world levels, to the extent that the question has been raised about whether the equation of trade as a factor of peace is still valid or not [24]. As stated by Pierre Hassner globalisation has tended to "morph into mistrust and hostility" [25].

The populist challenge and the threat of national divisions

The electoral rise of populism and the nationalist far right is a political fact of primary importance [26], although this should not necessarily lead us to overestimate their political weight at Union level for the time being [27]. The spread of the discourse backed by these political parties and the ensuing erosion of the fundamental principles, which form the heart of the European project are leading to a real danger of national withdrawal within the Member States. In spite of their diversity these populist and/or extremist political forces all disseminate an anti-European discourse that weighs over the political agenda and public debate in many Member States, notably in Austria, France, the UK, the Netherlands and Hungary, and even in Scandinavia. To a certain degree some countries seem to be protected from this due to their memory of authoritarian regimes. Southern Europe is for instance experiencing the effects of the far right to a lesser degree, probably because of the still vivid memory of the suffering from dictatorships. However several examples (Greece for example) seem to show that this memory is not a sufficient guarantee.

In this context, on the one hand the sovereignists, who tend towards nationalism, develop a defensive, closed vision of European national societies and advocate the closure of the borders to immigration and the restriction of free movement; on the other, the anti-liberals deem that European integration is occurring according to a neo-liberal economic ideology, which is leading to the dismantling of national social systems and must therefore be countered in virtue of this; finally some combine these two approaches in what might be called "left-wing sovereignty" [28]. The electoral rise of populism - both on the left and the right - just like the rise of the far right nationalists constitutes a real danger regarding the re-nationalisation of European policy. Beyond the development of types of national-populism [29], this re-nationalisation can take very different shapes and affect the European Union to different degrees: the attempt by national decision making bodies to control decisions taken at European level, whose democratic legitimacy is challenged for example in Germany; the desire on the part of some Member States - starting with the UK - to redefine the terms of their relationship with the European Union; finally the development of secessionist movements within Member States (Catalonia, Scotland, etc.).

Moreover the repeated crises that have affected Europe over the last five years have had significant repercussions on relations between Member States: the Franco-German relationship; the North-South divide; the issue of the UK's status; East-West fracture over the refugee crisis [30]. In the wake of the terrorist attacks in Paris and Brussels these events unite or divide. Solidarity and unity must prevail, but it is to be feared that these new tragedies will increase not only divisions within national societies but also between European States. The presence of jihadists amongst the groups of asylum seekers has affected the debate over immigration. The area between the front line countries, which are being accused (notably Greece) and the countries of Central Europe, which denounce the dangers of multi-cultural societies is full of pitfalls. The question of security policies cannot be ignored either: the failure of national security services has been emphasised (Belgium being the focus of criticism). In short, the return of the national glacis with the border as the only legitimate protection may still gain ground. In this context mutual mistrust can but grow and the Schengen area is under unprecedented pressure with the return of national border controls and the building of walls and security fences between Member States [31]. When this type of event occurs in "healthy" societies, it is difficult to recover; in societies that have been weakened by successive crises it is even more complicated.

Hence the project to unify Europe is in danger: if European leaders do not implement reform that will help them remedy these present shortfalls, European opening will give way to national withdrawal. However there is little chance that this withdrawal would provide more solutions rather than further problems. In particular renationalisation would not solve phenomenon that are beyond the national level: they would not stop migrant flows, they would not solve economic weaknesses, they would not make politics more ethical, they would not bring terrorist threats to an end. What is at stake is rather more the definition of the content of policies, and the lines of division on this point run through national debate. Finally national withdrawal would not remedy European disagreements, on the contrary. Acrimony with regard to "Brussels" would change to bitterness regarding neighbouring European States, which would assume the role of the scapegoat they had before European integration began and which still rises to the surface from time to time. A return to a national Europe would be a return to a history of political division that European integration has not made disappear but which has succeeded in neutralising with checks and balances.

Reviving work towards a united Europe

The status quo: an illusory choice. The paralysis of European "governance"

Faced with political divergence, the choice of a consolidated status quo might appear tempting from a short term perspective, since it seems that there are too many obstacles for the European Union to overcome the plateau it has reached in the last 20 years since Maastricht, with the internal market and the euro being the recent major structuring projects. The reasons for the difficulty in defining a medium to long term political project for Europe have now been pinpointed [32]: a lack of European leadership, the strengthening of intergovernmentalism [33], a tendency to fall back on the State in a context of increased international competition and of an unprecedented crisis since the Great Depression, and the threat of an ageing Europe remaining paralysed in a "catatonic state". In this context it would be tempting to give up, with a focus on consolidating the Union in its current form.

However this would be a mistake and the status quo is not a viable option long term [34]. If there is one thing that has been learned from the repeated crises that the Europeans have had to face it is that European "governance" has shown its limits both from the point of view of its efficacy and of its legitimacy. The gulf between the way the European institutions function at present and the needs evidenced by the crises is increasingly obvious. Diplomatic negotiation time is too long and the feeling has progressively developed that Europe is always one step behind the crisis. Moreover this mode of functioning is the cause of great anxiety: the negotiations' outcome is always uncertain, the positions adopted by the different governments seem to be regularly subject to electoral calendars, their decisions at European level can then be challenged at national level - especially in a context in which many governments have been sorely weakened politically in their own country. The ensuing uncertainty increases citizens' anxiety. Lastly the present "crisis management" methods, which notably give primacy to the European Council, lead to a problem of clarity and legitimacy for the citizens of Europe, since there is a lack of a real European democratic debate. Indeed a common political mandate is irreconcilable with the juxtaposition of 28 national political mandates. As stressed by Benoît Coeuré, "The raison d'être of this (intergovernmental) approach is, admittedly, to allow each government to sign up to shared decisions. However, experience shows that it does not ensure that governments take ownership of those decisions at national level. What is more, it does not prevent the polarisation of the debate at European level or the temptation to engage in nationalist posturing." [35] Finally this approach is not even satisfactory from a national point of view since politicians cannot commit in the domestic democratic debate on a new orientation of European policies since at the end of the day, the decision will be the result of a diplomatic negotiation with other heads of State and government.

All of this has a political and economic cost. The populist and extremist parties are on the rise in Europe, criticising the weaknesses of democracy, especially at European level, as they reject the present political and economic system. In fine this is leading to a general feeling that the status quo is increasingly difficult to maintain and that it will not last for long.

Reviving European ambition

Five years after the start of the crisis the European Union must of course strengthen its internal cohesion and notably continue the integration of the euro zone. It is incidentally the recommendation made by the report "Completing Europe's Economic and Monetary Union" prepared by European Commission President Jean-Claude Juncker in close collaboration with the Presidents of the European Council, the Eurogroup, the ECB and the European Parliament. This report acknowledges that for the euro zone to more than just "survive", for it to "prosper", it is vital to share European sovereignty within the common institutions based on adequately strong mechanisms of political legitimacy and accountability. Although this goal is necessary there is doubt that the need to strengthen EMU would be enough to make significant progress in terms of political integration. The opposite may in fact apply. The euro was first a political choice: it is in fact the political will to protect this common good and common institutions empowered to protect it (particularly the ECB and the ESM) that prevented the collapse of the euro zone. This political will and these common institutions are backed by strong support on the part of public opinion for the euro: more than two thirds (69%) of Europeans support the euro, with only one quarter being against it (25%), with 6 % giving no opinion. [36] The origin of this support is economic in part (protection against currency crises for example) but it is also geopolitical: the euro is the most concrete symbol of a united Europe. Hence it has become a constituent element of European identity and reflects the pooling of common interests in the global game.

If we follow this logic then the long term redefinition of the European political project is urgent. The rise of radical, populist and even extremist, Eurosceptic or Europhobic trends - both on the left and the right brings to light a crisis in European liberal democracy both from an economic and political point of view [37]. Deregulation has been linked to the disaster of the financial crisis and tax scandals (Lux Leaks for example). Moreover political liberalism is increasingly seen as a synonym for impotence, notably in the face of other models that are being put forward in the world: fascination mixed with fear regarding the Chinese model; attraction towards the Russian regime on the radical left and right. The liberal crisis is reflected in the political crisis of which the revival of populism and extremism in many European States is a sufficiently clear symptom.

The strength of liberal democracy is however that it is a regime that is naturally open to its own inadequacies and shortfalls. In the face of the crisis of democratic legitimacy, the fundamental challenge is to produce a common vision of the future of European integration to give it a clear purpose: a community of citizens does not just live by the law, the economy and regulations; it also lives according to a feeling of belonging to a political community as an area of choice. In the face of the economic crisis the proponents of an "open society" must admit that the quest for equality and solidarity (which led to socialism) and the demand for economic and social protection in a free-trade world is a fundamental human requirement. These aspirations were illustrated by the success of Thomas Piketty's book on inequality [38] and are just as legitimate as are aspirations to freedom. Likewise, in the face of the refugee crisis the reception of people fleeing countries at war is a moral imperative and a fundamental right; at the same time the quest for security must equally be taken into account. The history of the previous century shows that if citizens' demands and aspirations are not taken seriously there is a danger that they will be taken in hand by radical, anti-European political forces [39].

It thus appears vital to redesign European liberalism with the cardinal aim of protecting citizens against the excesses or inadequacies of political and economic systems. And this must be based on the critical acknowledgement of the limits of the organisational principles on which our societies are based, in particular the State and the market, freedom and security. In other words it means rejecting the ideological belief in the supposed identity of one of these principles alone with the general interest.

From an economic point of view European liberalism must acknowledge the limits both of the market and the State. It is clear that it is impossible to trust the market blindly: it can be self-referential in the short term (it is better to be wrong with the others than to be right alone), and experience brutal changes. Moreover, state intervention can be justified by externalities, the asymmetry of information, the need to compensate initial inequalities for reasons of social justice or the necessary definition of rules to ensure the good functioning of institutions such as the financial markets, the currency, and competition. At the same time it has to be acknowledged that State intervention is not omniscient or omnipotent and that it does not reflect individual preferences (and incentives) as effectively as a decentralised price system. It is also potentially open to risks such, as political clientelism, the capture of regulators by interest groups, nepotism and corruption. These dangers have fed criticism of the elites and fostered the rise of populism in many European countries.

Similarly from a political point of view, it is important to acknowledge the respective limits of the demands for security, freedom and identity. Each one of these is legitimate to a certain extent. But wanting absolute security, wanting to erase uncertainty or risk is eminently dangerous for freedom because freedom means a certain amount of indeterminacy, which is incompatible with the total control of citizens' actions. The demand for security can therefore never be absolute because this would lead to a closed, authoritarian society. Conversely freedom is not effectively possible without the minimum degree of security, which is safety, i.e. the fact of not seeing one's physical integrity under threat or subject to the arbitrary good will of the other, and without at least a minimal amount of social protection. By reformulating Rawls' first principle of social justice [40], we might say that our societies' goals should be to ensure the greatest security and freedom of individuals that is compatible with an extensive, constitutionally protected set of fundamental civil liberties and safety guarantees. This principle justifies State intervention as part of its regalian tasks that aim to protect civil liberties and, in their name, security whether this involves domestic or foreign security.

But although the European Union has a certain number tools to ensure the good functioning of the markets (notably via it prerogatives in the areas of competition, internal market regulation and monetary policy), its weaknesses have to be acknowledged in several regalian areas. In particular its ability to contribute to the stabilisation of economic cycles in the budgetary domain, or its role in maintaining security and the rule of law (for example the fight against corruption, counter-terrorism, or the defence and protection of the Union's borders), is very limited. Hence Europe's institutions were not adequately equipped in the face of the economic crisis and with regard to the request for a strengthening of the rule of law and security policies. It is not surprising then that many protest parties are just as critical of Europe's work as they are of national policies.

The ideas above are a rough outline for a European project that would guarantee citizens greater protection. For example, since terrorism is a transnational threat launched against Europeans, the Member States should pool resources in the shape of greater police and intelligence cooperation, in justice matters and with regards to defence by reviving Strategic Europe [41]. Recent proposals aiming to strengthen Frontex are a good example of the measures that should be taken and implemented [42]: developing integrated border management covering a wider field of players (coast guards and customs officers); moving to a system acting in the Union's interest at the Union's borders without the need for unanimous prior authorisation by Member States. Another concrete example to ensure the joint fight against terrorism, but also corruption and other forms of crime, would be to create a European Public Prosecutor's Office. This is already possible with the current treaties (article 86 of the Treaty on the functioning of the EU) which also provide the possibility for a limited set of States to take the initiative if the others are at first reticent. This type of initiative would help remedy the feeling many citizens have that Europe is "an open, unprotected area."

Standing together to face external challenges

This political project also needs an external dimension, which is too often and incorrectly disconnected from imperatives of internal cohesion. Reviving the European project supposes the provision of answers to the following: "What are Europe's collective goals? What are the public goods that require joint action? Obviously, the scope of such reflection goes beyond just the economic sphere; it also encompasses key determinants of power, such as technology, energy and even foreign policy and security. In federations, public investment in such common goods is centralised. Here in the European Union, we are a long way from that. And yet, we face the same international challenges." [43]. Political union between States involves an agreement over the issue of war and peace and in fine a minimum amount of unity in terms of foreign policy, at least between the States which count in these areas. The pooling of competences by the Member States in terms of foreign policy is in fact a focal point of any process towards political union. Overcoming divisions between Member States requires the revival of a debate over true political union, which should lead to discussing the joint exercise of some regalian prerogatives.

For several centuries power has been associated with State sovereignty. This results from three sovereignty levers: diplomacy, defence and the police. Diplomacy and war are par excellence the business of the State, the heart of sovereignty, the expression of the "Westphalian" functioning of international relations. As shown by military intervention by France in Syria and Africa, the tension between Russia and Turkey and the developments in Iranian policy, the Westphalian grid of analysis has not lost its relevance, however in a globalised world the individual power of EU Member States seems to be eroding and the need for unity to protect their interests and influence the global agenda is more vital than ever before [44].

However the idea of sovereignty is problematic in European affairs: the Union is not a State and other administrative levels are the focus of distributional conflicts. In this context the definition of the Union's task is not extremely clear to the citizen, who might wonder how his political rights work in a system that is highly influenced by bureaucratic/diplomatic factors. Moreover if there is one area in which Europeans agree to grant the State with a role, it is in terms of regalian tasks (budgetary decision, foreign policy, defence, immigration, police, protection of security, energy independence). But Member States have refused to entrust the Union with regalian tasks (in 1954 France rejected the European Defence Community, the constitution of a European defence system) to protect their own sovereignty. The Union has been granted tasks of redistribution (Common Agricultural Policy, Cohesion Policy) which cause conflict over appropriation. However in a globalised world it would seem logical for the Union to have regalian instruments. In reality it depends on the constitution of a European identity and Political Union.

Whether indeed we speak of radical Islamic terrorism, political changes in Maghreb and the Middle East, repeated tension with Russia, notably regarding Ukraine or the consequences of the now "relative" power of the USA, Europeans are facing an accelerated worsening of their collective security. Moreover the regulation of migratory flows, the fight against climate change, the strengthening of energy supply security and the fight to counter inequality and poverty, are all equally international issues in which European action is confronted with global challenges. The European narrative focused for half a century on the economy and introversion. Now we have to provide it with the political and external extension for the coming decades, with a view to involve Member States and citizens in new common projects. The Union must turn towards the world which is changing rapidly and adapt to the world's evolving balance of power [45]. This supposes that the Union will adopt a change in perspective in terms of its place in globalisation both from an economic and strategic point of view. Too often the European Union does not think strategically and in doing so prevents itself from enjoying greater influence in the international arena as it restricts itself to a technical approach that is often useful, sometimes effective but rarely decisive. It is accustomed to the deliberation of the "forum", and indeed membership of the Union has pacified the relations between Member States; it must now defend its values and interests in the "arena" [46] of international politics. The challenges that the Europeans face are vast since the ingredients that have helped towards their peace and prosperity are now being questioned. To be both real and sustainable the revival of the European integration project needs to be given a clear political horizon with a strong sense of purpose and a renewed narrative.

For the European Union "the most decisive aspect is undoubtedly of vital essence: its internal dynamism, its ability to adapt without betrayal, innovating whilst agreeing to open its doors, to debate and cooperate with others without losing its identity (...). But the thing that is lacking is a dose of vital energy, self-confidence, ambition and on the other hand awareness of its unity. If passions are being released elsewhere, the Europeans for their part are not passionate about their common project. Passions exist at national level, but they often tend to be defensive and negative. A European ambition has to be either created or revived." [47]

***

Given the sharing of common regalian prerogatives that this political project implies, debate over the Union's political dimension must be taken up once more. Indeed although the crises that are affecting Europeans should help set the terms of debate over true political union and over the issue of the Union's political regime, the continuation of Europe's integration cannot content itself with moving forward at a forced pace, out of necessity alone. A project like this must be undertaken according to a previously set design and with adequate political legitimation. If we want to give European policy a sense of purpose, we must remedy this lack of "backbone" without undue delay and dare to debate publicly the content that should be given to the future direction of the European project.

This debate should contrast three choices:

Firstly that defended by those tempted by the return of "old Europe" and national withdrawal. A scenario like this might seem tempting to many citizens who express the legitimate expectation of protection, since it gives them the feeling that sovereignty has been recovered in terms of regalian choices and security as part of a political framework deemed more "natural" and more protective: the nation state. However this option is incredibly risky both economically and politically with the perspective of a fragmented, divided, weakened Europe.

Then there is that of the status quo, at best the consolidation of the Union following the various shocks that have been affecting it, but without reforming the whole. This would be a mistake, since the status quo is not a sustainable option long term and it would therefore be illusory to content oneself with the consolidation of our acquis. History has shown that, in a crisis context, a political system can end up disappearing by fear of reforming itself.

Finally there is that of the supporters of a Union of nation States that is open to the world: in the face of the "malaise" felt by many Europeans a long term intellectual and political project is necessary for 21st century Europe, if we do not want our societies to close to the modern world. This project must be that of rebuilding a political, economic and social model that is specifically European - reconciling freedom, solidarity, values that form our common identity, security and international influence - to make it "competitive" in the world competition of civilisation models and political and economic systems.
