Many of the major trends of international politics in the twenty-first century are best seen from Ukraine. Understanding the Ukrainian revolution of 2013-2014 and the Russian invasion that followed are absolutely essential to any informed discussion of the state of the world. This book, rich in chronology, evidence, scholarly analysis, and human insight, is a major step toward such an understanding. It should be widely read by those interested in Eastern Europe, the European Union, digital war, and the possibilities for new forms of politics.–Timothy D. Snyder, Richard C.
