No, the heads of NATO, Ukraine and Russia shouldn't be rewarded for their acts of violence against the people of Russia and Ukraine. All sides should withdraw from the territories in which they are not welcome by the people.
Also Russia didn't invade Ukraine to "gain new territory", do you know when the war started?
(Furthermore its important to clarify that although Russia is a neoliberal hellpit, NATO, using Ukraine as a meat shield for their interests, is way, way worse, literally headed by one of the most evil countries that ever existed: the USA, as such, it is foolish to trust that anything they do in this situation will help the people of Ukraine, including dump military hardware into the region for disposal and testing)
Your Ukranian "people":
(its mostly fascist paramilitaries funded by god knows who)
Your "voting":
(there was no democractic referendum held to oust the president)
Also, the west itself is a white supremacist fascist entity who went to Ukraine in 2014 to put pressure on Russia by cutting off potential allies. They are not the good guys.
Again, how are peace talks and settling matters via negotiation being "in favor of a fascist government"? Why are you so in favor of expanding the global influence of a fascist organisation (NATO) via the continuation of the war? Why are you opposed to the people of the Donbas being free from the horrors of civil war at the hands of the Ukranian military? Did you know that the majority of people in the Donbas are ethnic russians, and are pro-separatist? Did you know that this is the reason why Ukraine started shelling the fuck out of them and decided to sic their Nazi dogs on them in 2014? Why are you in favor of continuing a bloody war when a mutually beneficial agreement for all sides, even with respect to pre war conditions, can be reached from peaceful negotiation?
This is projection, the left has consistently been anti war this entire time, yet liberals are on the side of outright fascists in the ukranian military being given experimental weapons when they are not outright denying they exist.
