President Vladimir Putin of Russia developed a foreign policy doctrine of ethnic war. This argument from language to invasion, whether pressed in Czechoslovakia by Hitler or in Ukraine by Putin, undoes the logics of sovereignty and rights and prepares the ground for the destruction of states. It transforms recognized polities into targets of willful aggression, and individuals into ethnic objects whose putative interests are determined from abroad. Putin also placed himself at the head of populist, fascist, and neo-Nazi forces in Europe.
