5In this timely and incisive book, Sergei Medvedev argues that Russia's war in Ukraine was not merely a whim of Putin's obsession: rather, it was the result of two decades of authoritarian degradation and post-imperial ressentiment, a culmination of Putin's regime and of Russia's entire imperial history. Building on his prize-winning book The Return of the Russian Leviathan, Medvedev argues that it was not only Putin that started this war, but Russia itself, which, by and large, has imagined and embraced it with enthusiasm, seeking to relive its own military glory and colonial past.
