Yeah, probably. You invade a country without a good reason ans kill civvies, why wouldn't retaliation be on the table?
You don't get to invade a country and maintain any sort of moral high ground. Israel, the US, Russia. It's all the same shit at the end of the day. But Tmthe US sucking doesn't automatically make their opponents the good guys. Russia sucks too and you would have to be a completely brainwashed moron not to realize that.
