Look you pathetic piece of shit imperialist. The war was started a long time ago by the United States' expanding NATO, a "defensive" cold war military alliance that is inherently hostile to Russia, operationally, strategically, and historically. etc, into Eastern Europe, right up to Russia's border. Western Ukrainians lean towards the EU and the West in general, politically and otherwise, but that's not the case in Eastern Ukraine where most Ukrainians are ethnic Russians. Russo-Ukrainians have close ties with Russia, culturally, linguistically, and politically. Their political allegiances differ from that of Western Ukrainians, so what the hell did you expect was going to happen when in 2014 the US orchestrated a coup d'etat in Ukraine, ousting a Russian-friendly president, i.e. Viktor Yanukovych with a Russian-hating ultra-nationalist i.e. Petro Poroshenko? Did you expect the Russo-Ukrainians to just go along with the coup and accept the results? The fascists are the Ukrainian ultra-nationalists who engaged in a murderous terrorist campaign against Russo-Ukrainians for not "rolling over"
(using your own words) and accepting the results of the US-led coup.
Russia doesn't have 700+ military bases and installations around the world, the US does. Russia wouldn't be fighting this war if the fascist-run Kyiv government would've implemented the Minsk agreements and established peace with the Russo-Ukrainians of the Donbas. They refused to do that. So play stupid games, win stupid prizes. Take your Russian medicine biatch.
