I don't see people on here saying Nazis are the reason it started so much. Most people's take is that Russia is lashing out against encirclement by opposing powers, and also to annex parts of Ukraine that according to polls, don't want to be part of Ukraine anymore.

Western funding of Nazis is just a tried and tested mechanism of levering power against a state.

It's not the reason that Russia started their offensive, but it is a fact that the CIA funds right wing militants to fight on the behalf of the USA's economic interests. They have done so time and time again throughout history, from Europe to Asia to Africa.

Now, as Ukraine rules with western support, they have outlawed left wing parties. This has rather predictably ended with higher rates of admiration of the Nazi Stepan Bandera, the repeal of labour laws, and the mass privatization of the country.

This is typical economic shock doctrine. If Ukraine wins, its people will be the new low wage manufacturers and workers for the world to use and discard for profits. If Russia wins, it's also not great at this point - they'd likely be contending with western funded guerillas, and who knows if Russia would actually reinstate the repealed labour laws and left wing parties, given that Russia itself is a capitalist oligarchy.
