1. Ethnic supremacy supporting genocide of “inferior” is the lesser criteria.
2. Anti-communism. The major centrality.

Germany’s resentment of Jews stemmed from German zionism’s cooperation with US to defeat Germany in WW1, and Jews as communist leaders in Russia and Europe, as well as Jewish diaspora voting for the main (communist) opposition party in Germany, before Reichstag fire provided opportunity to ban the party.

Ukraine’s ethno-nationalism is heavily inspired and celebrating, at the top ruler level, of its ww2 nazi collaboration path that included extermination camps and SS divisions massacring other ethnicity non soviet occupied/protected villages and towns. Today’s demonic support for Ukrainian nazis from Europe is entirely motivated by Stalin/USSR derangement syndrome, and there is no hate the US won’t politically manipulate to subjugate idiots into devoting their subjugation to a war on Russia.

Nazis and Islamic fundamentalists (Syria and Iraq examples) are self-motivated destabilizing agents for US empire. Romanian NATO intervention in democracy is a reaction against “far right anti-nazi”. Anti-naziism is now a anti-zionist position. Neocon diaspora supports outright naziism in Ukraine and Israel, and the brainwashed left that tolerates naziism and Islamic fundamentalist agents of Empire is no obstacle to far right at home that includes in US a neo-nazi faction that hates muslims and loves Israel to the point in attacking university BDS anti genocide protesters. The level of American brainwashed stupidity supporting your own slavery and oppression is beyond comprehension, except for the fact that DNC got the election result that it thinks is the most sustainable for the neocon Israel first DNC, and that is beyond morons comprehension level.
