History dealt another real slight to ultra nationalist Ukraine by crediting the rise of Nazism to Adolf Hitler. After WWI Germany also moved into the Hapsburg model of independent governance. Hitler wasn't original, he just developed into the big kid on the block. Nazi Germany had little use for Nazi Ukraine until after the war started. German Nazi ideology was based on industrial fascism, while Ukrainian ideology was based on agricultural fascism. Ukraine was seen as a backwater to the German ultra nationalists at the time, and this hasn't changed.
Following the WWI breakup of the Austria-Hungary Empire the Bandera were an ideal fit. The Germans were the sister empire to their own and they expected the same kind of treatment. That fact made it natural for the Bandera to swear allegeance to the Third Reich forever. It was a slap in the face when they didn't get the same rights they had under the Empire. This fact, coupled with Hitler losing the war are the only reasons they hate being called Nazis today.
It's also why in some of the private armies operating in Ukraine today they swear allegiance to the 3rd Reich ideal.
Anyone who has followed Ukraine at all is well aware of Bandera's activities in WWII. The genocide of over 500,000 people in Ukraine, the SS Divisions that the ultra nationalists manned, fighting against both the Soviet Union and the Allies. The Bandera SS Divisions also manned the concentration camps that became extermination camps during the war. The Bandera have never stood trial for crimes against humanity, and never even had to apologize.
In 1946, three developments happened that profoundly changed the world we live in. The first happened as the ultra nationalist Ukrainian emigre populations settled into their host countries and started to participate as dual citizens. Keep in mind that other than for a few brief years, Ukrainian ultra nationalism only existed as a government in the diaspora. The first the Ultra Nationalists were political extremists from a tiny region and afterward only existed as a standing army.
During and after WWII, the Bandera army moved out of Ukraine, emigrating as a nazi army to host countries all over Europe, Scandinavia, Australia, and further West. The Bandera were comprised of at minimum 4 Waffen SS divisions as well as the large civilian army they maintained for genocide.
The Bandera started taking public office as citizens of the host country and maintained representation in the Ukrainian government in exile. They joined political parties and pushed the host countries political ideologies toward the far right as they went. They worked together as a bloc to push for the destruction of the Soviet Union and the reinstatement of a government that would become Nazi Ukraine.
Eventually, as office holders or adviser's they were in position to push Bandera's objectives in conjunction with the government in exile. The other Bandera (all associated groups) described under the Promethean project and below did the same thing, working hand in hand with the Ukrainian leadership. Eventually this mix dominated all of Western politics, especially the conservative and ultra liberal parties whereever they went by stoking nationalist fervor and pride - or Exceptionalism. After 1947 they were recruited as agents in the cold war. Eventually across Europe and the West they would run the cold war and gain access to the highest positions of power on the continent.
