Regular predictions announcing the "death of the Schengen area" have been rather excessive, if not meaningless. Indeed, they echo the high tension that opposes the 26 countries sharing this area, notably becoming clear during the massive influx of refugees in 2015-2016 and then during the terrorist attacks of the last few years. Tension like this is symptomatic of a double crisis, whose causes must be identified to provide effective remedy: an often-mentioned solidarity crisis between the States of the EU, but also a confidence crisis, which reflects the difficulty in sharing a so-called area "without internal borders."
