The only real anti-war position on the Ukraine conflict is support for de-escalation, diplomacy, and detente. Yelling "PUTIN BAD" and calling for escalations that could lead to a very fast, very radioactive WWIII are not anti-war, and indeed such sentiments are being exploited to prolong this war.

No efforts are being made toward diplomacy and peace, only toward escalations like building an insurgency and unprecedented economic warfare which fit perfectly into pre-existing US agendas against Russia. This is in the exact opposite direction of peace. 

De-escalation is a skill we're meant to start learning in kindergarten. These people act like they learned their de-escalation skills in the Minneapolis Police Department.

If you want to keep screaming that Putin is Adolf Hitler and even insignificant concessions like promising not to add Ukraine to NATO would be Chamberlainesque "appeasement" then go ahead, but don't pretend you're anti-war or pro-peace, because you're not.
