the ussr literally engaged in a generations long "cold war" with the us and nato. economic warfare, propaganda warfare, espionage warfare, cultural warfare, literal proxy warfare, reciprocal threats of unironic nuclear annihilation, absorbing surrounding nations, etc etc. and yes they lost and collapsed. again, i point out- if the us collapsed in 1990 would i find it bizarre if the ussr started getting their feet into mexico or canada? not at all. what did they think would happen after the ussr collapsed. all just water under the bridge huh?
