Russia doesn't want other nearby countries to become democratic or fall outside of their direct control. They also like having puppet states surrounding them (which makes sense given their history of being invaded). But unlike Russia, the US has not expanded its borders since WWII by invasion or force. Russia has and looks to do it again. That is a sign of expansionism by force. Human history is full of such domination of neighbors and it has been ravaged for thousands of years, with the exception of when the US had become a superpower (which has stabilized most of that aggression in Europe).
