title: Introduction
abstract: The idea of this book is inspired by the widely spread assessment of the conﬂict in Ukraine and its repercussions as marking a radical departure from ‘normal’ post-Cold War relations to a drastically new type of international (dis)order. The military conﬂict in Ukraine, including Russia’s annexation of Crimea and support for militant separatists in the so-called Novorossiya, has indeed undoubtedly been a game changer for policy makers and military planners in the whole of Europe and far beyond.
