This timely book astutely charts the transformative effect of the war in Ukraine on the EU, from both a legal and policy perspective. The EU, itself a unique peace project born out of two world wars, consistently evolves from one security crisis to the next. Departing from the usual broad sweep of deepening and widening, this book focuses on the constitutional and substantive impact on the EU of the recent war in Ukraine. More so than ever before, this particular war proves to be a truly pivotal moment for the EU. Drawing on expert contributions from both academia and the EU institutions, this book offers a masterful exploration of how the EU is being challenged to the core.
