>> From that disbanded party, Svoboda Party sprung out. They publicly dis-avowed Neo-Nazism. <<
Not sure what you mean by “publicly disavowing Neo-Nazism.” The Socialist-Nationalist party was outlawed as Neo-Nazi, so they had to disavow Hitler. But they openly call for the extermination of Jews, the establishment of a socialist-nationalist government, and literally worship (as in construct alters and shrines) to the Banderites. So, since the Banderites WERE Nazis...
Hitler disavowed Bandera first, the Nazis had no use for them.
There were also Russians (General Vlasov), that will willing to fight alongside the Nazis, but also, Hitler declined their help.
Banderas was a Ukrainian nationalist who was a defender of Ukraine against the Russians who with Stalin had starved to death 7 - 10 million ethnic Ukrainians.
Banderas then welcomed the Nazis as liberators only to find out that the Nazis wanted to exterminate ethnic Ukrainians. Along with the 1 million Jews who were killed by the Nazis in Ukraine, the Nazis also exterminated 5 million ethnic Ukrainians. Banderas himself was sent off to a Nazi concentration camp.
Beyond all that Banderas was also responsible for the repugnant ethnic cleansing in W. Ukraine of Poles.
Fast forward to a decade ago and you have Putin and Russia ethnic cleansing ethnic Georgian Christians in S. Ossetia and Abkazia.
That's a more detailed picture for you.
