-depth analysis of the war in Ukraine, Paul D'Anieri explores the dynamics within Ukraine, between Ukraine and Russia, and between Russia and the West that emerged with the collapse of the Soviet Union and eventually resulted in Russia's invasion in 2022. Proceeding chronologically, this book shows how Ukraine's separation from Russia in 1991, at the time called a 'civilized divorce, ' led to Europe's most violent conflict since WWII. It argues the conflict came about because of three underlying factors-the security dilemma, the impact of democratization on geopolitics, and the incompatible goals of a post-Cold War Europe. Rather than a peaceful situation that was squandered, D'Anieri argues that these were deep-seated pre-existing disagreements that could not be bridged, with concerning implications for the prospects of resolution of the Ukraine conflict
