No one is "building a fortress around Russia", least of all the Western allies. The Russian western border is a small part of their territorial limits. Ukraine is an independent country and can decide who they want to ally with, clearly it's not Russia. He got pissed off when Ukrainians elected a leader that was not a puppet of Russia. Now he is exacting revenge because he doesn't have a tacit Russian territory like with Belarus any more. When Finland and Sweden decide they need the defensive advantages of NATO is he going to invade Scandinavia too? Should they be force to be "permanently neutral" as well?
