The European Union is the world\u2019s most successful experiment in shared sovereignty, and its biggest, wealthiest social welfare state. It also has struggled with nationalism and fragmentation in the face of crises, from the 2008 global financial meltdown, to the 2015 migration wave and subsequent rise of the far right, to the ongoing stresses caused by the COVID-19 pandemic.\nIn what ways has the European model worked, and in what ways has it failed? Only a revived international order can address global problems like health, finance, and climate change. Veteran observers of the European Union discuss the continent\u2019s response to COVID-19, and suggest lessons for international cooperation going forward.\xa0\nParticipants include:\nDavid Carretta, journalist, Brussels\nRolla Scolari, journalist, Milan\nThanassis Cambanis, senior fellow, The Century Foundation
