1. they were passing legislation that oppressed in large minorty. 2. they subverted their own democracy. 3. they renged on a UNSC endorsed peace agreement that the head comedian promised to implement the peace deal. 4. Comedian then did a 180 (maybe bribed or threathend) 5. Ukraine was building up a force to attack Donbas (hint the war against this large force has taken more then a year and is still ongoing) 6. Ukraine refused to maintain its neutral status and wanted to join NATO, which Russia views as a threat. Almost every nation in nato has attacked Russia in its history. We are already hearing the US complaining about a PLA liasion office in Cuba and a Chinese secuirty agreement with effin Samoa. So please don't tell me this is "has no basis bla bla bla" Russia offered to negotiate options, the US said "fuck off go and attack Ukraine if you dare" and so here we are.
You have the Kremlin talking points down. I'm sure Putin is smiling down on you.
