The book deals with the urgent need for the EU to position itself globally in the wake of Brexit, a rapidly worsening climate crisis, the COVID-19 pandemic, an aggressive Russia, and an ever more assertive China. After 60 years of intensive navel gazing that focused on institutional design more than world politics, the EU is now forced to defend its liberal democratic values, which have come under attack from inside and outside the European integration project. Moreover, Realpolitik is back on the agenda. Europe’s content negligence of defense matters in the past few decades has been revealed by Russia’s war of aggression against Ukraine.
