The West has woken up to the uncomfortable fact that Russia has long believed it is at war with them, the most egregious example of which is Vladimir Putin's hacking of the US elections. For Western governments, used to believing in the post-Cold War peace dividend, it came as a shock to find the liberal international order is under threat from an aggressive Russia. The 'End of History - loudly proclaimed in 1991 - has been replaced by the 'Return of History.' Putin's War Against Ukraine came three years earlier when he launched an unprovoked war in the Donbas and annexed the Crimea. Putin's war against Ukraine has killed over 30, 000 civilians, Ukrainian and Russian soldiers and Russian proxies, forced a third of the population of the Donbas to flee, illegally nationalised Ukrainian state and private entities in the Crimea and the Donbas, destroyed huge areas of the infrastructure and economy of the Donbas, and created a black hole of crime and soft security threats to Europe. Putin's War Against Ukraine is the first book to focus on national identity as the root of the crisis through Russia's long-term refusal to view Ukrainians as a separate people and an unwillingness to recognise the sovereignty and borders of independent Ukraine. Written by Taras Kuzio, a leading authority on contemporary Ukraine, the book is a product of extensive fieldwork in Russian speaking eastern and southern Ukraine and the front lines of the Donbas combat zone. Putin's War Against Ukraine debunks myths surrounding the conflict and provides an incisive analysis for scholars, policy makers, and journalists as to why Vladimir Putin is at war with the West and Ukraine.
