How does that fit with the Nazis forming alliances with Italy, Japan, Bulgaria, Croatia, Thailand and even China at one point? Hitler agreeing to a pact with the Grand Mufti of Jerusalem to further German nationalism in the Near East? Then they had Muslim SS officers that had to stop training multiple times a day to pray to Mecca. Because Hitler was so anti-internationalist, the Nazis were eager to host the Olympics and invite people from around the world to show off their regime? What were they doing in Africa, were they defending the interests of the German state in the Sahara?

Don't be blinded by their propaganda, both Stalinism and Hitlerism and any totalitarian ideology is inherently internationalist. Because they tolerate nothing beside and beyond their own ideology, so they end up getting involved with the entire world always. It's about control and these regimes do not stop until their are either defeated of control the entire world.
