Hitler's theory of a second Aryan invasion did come to pass in Europe. Because of World War II, there is more white people in Europe then there was before the war. This is because he killed all of the people who did not fit his profile, leaving less of them to procreate.
Adolf Hitler claimed the superiority of the Aryan race would take over the world. For a couple of years in Europe, Hitler's vision came true when he conquered France, Poland and Belgium. His alliance with Italy and Spain made most of Europe under Hitler's control. He tried to expand into Africa, the Middle East and Russia which was his mistake. Hitler went too far, too quickly. Instead of waiting and building up his forces, Hitler was spread too thin to do any good. For a few years, though, the Aryan ideal in the form of conquering Europe was realized.
Hitler's theory of a second Aryan invasion did not come to pass in Europe. This did not happen before he was taken down and killed as the leader. I think he intended for this to occur but he was killed before he could accomplish any more terror in his country.
Hitler's theory of a second Aryan invasion never came to pass in Europe after his demise. The fact of the matter is that another uprising like the Nazis won't occur any time soon. The world is becoming a gradually more accepting place, and an Aryan invasion wouldn't be tolerated today.
Hitler killed a shocking number of people in the quest for a theory of racial purity that doesn't even make sense, particularly - 11 million people in all of the camps, and countless others in the war. Today, Europe, though still quite homogeneous, is receiving a large immigrant population proportionally.
