We’ve known that Bear geopolitics is truculent.
There was an era when Russia headed a huge empire. Did this make them happy?
Modern commerce has, at least, gotten them to simmer down some. Being a major oil power helps.
I don’t know how much they’ve simmered down though. I don’t think they were very happy during the height of the Soviet Union. The people not in the party surely weren’t.
I think some leadership there is seeking glory, and expansion is the only way they know how.
