The jealous and intolerant eye of the Kremlin can distinguish, in the end, only vassals and enemies, and the neighbors of Russia, if they do not wish to be one, must reconcile themselves to being the other.
No matter how big and powerful, Russia always feels threatened. Even when they are feeling weak, they bluster and bully to hide their vulnerability. In this sense, Putin’s policies and beliefs are largely consistent with Russian history and the legacy of the Russian Tzars.
—George Kennan
