They set about changing street names, building names etc.to name them after Bandera and his followers. Discriminating against Russian speakers. Took up arms and waged war against those in the Donbass that is a civil war. They spent years and years bombing the Donbass and killing people.
These Nazi's were exposed, but when the US Empire decided it needed a proxy war against Russia, them same Nazi's were,/are the darlings for some in the west. Russia intervened in the Ukraine civil war, only after the Nazi controlled government built up a large military to attack Donbass and to wipe them off the face of the earth. Echoes of what the Zionists are doing in occupied Palestine.
Any side the US Empire backs is the wrong side to support. They do things that suit them and sod the rest of the world. They've spent 95% of their existence involved in some sort of thing warfare. War is in their DNA. Defeat for the US Empire anywhere is to be welcomed. It gives a boost to the anti colonial, anti imperialist forces in the world. As did it's defeat in Vietnam in the 1970s. It's losing this war in Ukraine, and that has played a major role in inspiring the anti colonial outbreaks in Africa. Similarly, the humiliating defeats in Iraq, Syria and Afghanistan has emboldened the anti colonial movement against apartheid Palestine.

Zelensky stood on a platform for peace with the Donbass. He approached the right wing Nazi lot and told them they'd have to lay down their arms. They told him to sod off and watch his back. The fascists run the show in Ukraine but they're getting beaten and this is causing splits and recriminations. The west has bigger fish to fry and are ditching Zelensky as they ditched Afghanistan.
