Russia literally invaded everyone around them. Look at all the former USSR counties.
The US has been involved in a lot of places but that’s not a justification for Russia attacking its neighborhood.
27 million Soviets died liberating these people from the Nazis, and this is the thanks they get.
Does Russia invading Ukraine justify the US invading Iraq?
Though we are discussing individuals here, should we ban Americans in projects to maintain moral integrity?
BTW are you referring to historical (pre 1990) expansion as well? Because an American really shouldn’t want to go there.
