If you are an American, Yockey makes fascism relevant for you. Otherwise I think American Nazis and far-right seem like very silly people who are not grounded in reality. Yockey deserves to be taken seriously. He was trying to put Fascism back into action immediately after WWII. He wasn't simply a writer and is probably best not thought of as a philosopher. He was writing propaganda and traveling across Europe trying to establish contacts and forming political groups (European Liberation Front). His writing style can be easily lampooned, but it was precise and often profound. More than that, his books are enjoyable and easy to read. They didn't catch on, and the West is totally fucked, but Yockey is wholly admirable in my book.
Yockey's views hardly change at all in The Enemy of Europe. He still considered the Russian to be an imbecilic brute (which I fully agree with). Yockey didn't want any meaningful alliance with the Soviet Union. He merely considered that the US was a more dangerous enemy to European culture. He considered that in the event that Europe could ally with the Soviet Union, the Russians would have nothing culturally to offer to Europeans and would have no influence on European culture. He thought it would be great if the Soviet Union invaded all of Europe because he felt that the Europeans would never accept Russian domination and would rise again with a great war of liberation. Nowhere did he ever say "Russians are good people, and we should ally with them."
And since you mentioned the Strassers, I'll note that they weren't actually pro-RussianCommunist either. In his books, Otto Strasser was extremely critical of Russia and considered Stalin to be evil. Otto Strasser frequently referred to the Nazi-Soviet non-aggression pact as evidence that the Hitler regime was evil. Hitler was so evil that he would briefly ally with Stalin! That was Otto Strasser's view, and he never bothered to alter his views after Hitler invaded Russia that this meant either party was less evil.
