An inevitable escalation in the war that started in 2014 with the US-backed fascist coup in Ukraine that goes against the interests and wishes of Eastern Ukrainians

and the subsequent killings of ethnic Russians in Eastern Ukraine, like Donbas, DPR, and LPR, by the coup gov for resisting.

I don't support the invasion per se. In fact, its goal of suppressing fascism in western Ukraine seems to have kinda backfired from this after all, with the Ukraine gov using this as an excuse to suppress the left.

But the point is, what else could've they done? They’ve already tried to join NATO multiple times from even before the USSR’s overthrow and have been denied (since it's an imperialist org whose entire purpose is to suppress socialism globally, and particularly Russia) and they already had the Minsk agreements which the US sidelined through the coup. Not doing something about it would lead to the continued killing of ethnic Russians in eastern Ukraine, and NATO getting even closer to Russia since the post-2014 US puppet gov doesn’t abide by the Minsk agreements.
