I don't know that he really thought that far ahead.
If he was able to conquer Britain and Russia, he might have expected us to make peace with him.
Hitler was a racialist, but he was so obsessed with Germany that it's hard not to call him a nationalist.
He had a vision for the world under him, even if hadn’t quite planned it out yet. He still had to consolidate his European gains before he could go farther.
I’m only making the point that he wasn’t really a nationalist. The left, of all kinds, have always believed in a one-world government. He was an aryanist. He wanted what he understood about Aryanism to be the philosophical bent of the German goverment. Nationalism, to him, was just a means to a greater end. He had no intent of being satisfied with a Europe that was ruled by Germany.
Adolf Hitler on the Battle of Tours
Albert Speer, Hitler’s Armaments Minister, described how Hitler expressed approval of Islam, saying that Hitler had been particularly impressed by what he had heard from a delegation of Arabs. When the Muslims had tried to penetrate Central Europe in the 8th century, they had been driven back at the Battle of Tours; if they had won that battle, the world would have become Muslim (maybe). Theirs was a religion, Hitler said, that believed in spreading the faith by the sword and subjugating all nations to that faith. Hitler considered that Islam was perfectly suited to the “Germanic” temperament and would have been more compatible to the Germans than Christianity.[52]

He was only racial against the Jews.
He didn’t really have a known problem with other minorities, just Jews.
