"just so we can say fuck you Putin"? Really? That is how you are attempting to frame the situation of a clear victim defending itself against an aggressor that has been appeased for years now?
So you believe that the attacking entity should always win, no questions asked? Is conflict to be avoided at all costs? Can I come into your home and just claim your house if I threaten to escalate with violence? You wouldn't want any conflict, so the right move would be to just give it to me.
Nobody is saying that.
Depending on the topic you can easily call it victim blaming too.
Somewhere you have to draw a line, you can choose for yourself whether that line is the Ukrainian border, Kiev or France. But you too will find that you have a line. Or maybe you don't.
