Actual real Ukrainians are fighting, and signing back up even after being injured.
Ukraine is on "death ground" and has nowhere to go except to fight to survive. Ukrainians know that. Russia knows that. I'm not sure that those that spout Russian propaganda know that, and for example I doubt you know any Ukrainians with questions like yours, but you sure do sound like the Russian propaganda lines that get trotted out to Americans.
Maybe I am subject to propaganda and you aren't, either way I'm on the side of peace. You are on the side of war and death. I'll take the propaganda.
And "we" here means the democratic world - solidarity is the only way to deter bullies - if Russia knew that EU/US would retaliate in case of an attack on Ukraine, they wouldn't invade.
But of course if you yourself is a bully, you will do everything in your power to cause feuds. And here we are, oh well.
