Russian aggression against Ukraine

Russia's aggression against Ukraine is arguably the greatest challenge to European security since 1945. Not only does it represent an attack on the very foundations of the international law system, but it also raises, with new urgency, the question of how far the offensive ambitions of the current Russian regime extend. This monograph sheds light on the broader background of Russia's latest aggression and provides an analysis of the developments in Ukraine after 2014 in the context of the current armed conflict. It dissects its main causes and sources, explains the functioning and course of Russia's hybrid warfare campaign, and assesses the impact of the ongoing Russo-Ukrainian war on the existing international order.
