Yeah, everyone Russia has invaded has been for defence. Sure buddy. The real world is more complex than a 4X game, but even then you can use that to understand why someone would invade another country. They wanted to steal the resources and population. You may use your statement as a justification, but it is never the actual reason. The excuse of it being defensive is rediculous. Yeah, invading a sovereign country (multiple times) is sure to make the alliance "encircling" you stop. Seriously? Do you believe that rhetoric or are you just saying it because you're supposed to?
