So you think that the Ukrainian army will kick Russia out of the Donbass and Crimea and Putin won't press the red button? I'll say the same to you,take care.
So you think it was reasonable for Ukraine to just embrace the big russian bear and give over their entire country? Because that's what Russia is asking for.
If you honestly believe that when Russian leaders, Putin or otherwise, say "we won't attack afterwards" - you're the definition of stupid, sorry.
If you honestly believe that peace is/was an option after they denied calling it what it is - uncalled for aggression (a.k.a. war) because they deemed territory that isn't theirs to be theirs - it only gets worse for you, my friend.
Also actual LOL at "BUT AMERICA DOES IT AND WE'RE ATTACKING BECAUSE AMERICA...", nah, whataboutism by world leaders, which is unbelievable but here we are; it had 0 to do with America or the UN when Russia attacked, but they probably expected what you want the Ukrainians to do - just roll over and give up. Which they didn't, and then others started helping the nation that got attacked, which is absolutely normal and has always happened in wars.
As I asked 10 times today - as you're (apparently? I dunno really) an Irishman - England declares "special operations" in Ireland tomorrow, demands you roll over and give up or they nuke you and instantly carpet bomb random locations full of kids and civilians. Do you (as a nation) go "oh, okay then, we surrender this uncalled for attack for no reason"? Or do you go "nah, not having that" and fight back?
"Special operation" btw.
