You have a rich fantasy life, kid... Or very bad sources of information.
As for "hardly have any Nazis" -

There's been (what are essentially) Nazis, in Ukraine since the 1st World War - particularly in the western areas, like Carpathia. They seized power with a CIA-orchestrated coup in 2014.

So then...why wait 8 years?
It's because the US ("NATO") had been building Ukraine an Army, under the cover of the Minsk Agreements, which Ukraine had never honored, but which Russia did. They got snookered by the West, as Francois Hollande and Angela Merkel have both admitted.
By the Fall of 2021, the Ukrainians had begun massing troops on the borders of the DPR, LPR and Russia. They were also cutting off water to Crimea. Then Zelensky started talking about joining NATO (as instructed by his handlers in UK/US Intelligence - despite the fact that he'd already been told that wasn't going to happen) and getting Nuclear weapons (minutes from Moscow), at the Munich Security Conference. These were all deliberate provocations, on the Red Lines previously spelled out by Russia, to the West. And Russia responded proportionally, and accordingly to these escalations in the conflict.
THEN Ukraine began to massively ramp up their warcrimes (deliberately shelling civilians and non-military infrastructure) in the Donbass - as reported even by the West's OSCE. Russia made one last attempt at a diplomatic resolution in December of 2021 - and NATO laughed in their faces. Bad Move. This war was ALWAYS the US/NeoCon plan.
