Europe's longest period of peace correlates with the existence of the EU. Most EU citizens have never known war. Not knowing what the EU protects them from, they feel they have nothing to lose by leaving it. There is nothing "inevitable" about the breakup of the EU, just as there was nothing inevitable about the Brexit. These departures require massive efforts on the part of small, motivated groups, who rely on enormous falsehoods to draw the vote of ignorants. Nigel Farage is already backing away from Leave's promises on healthcare.
