What did the Nazis think of Native Americans, Indians and Iranians?

I can't stress enough how irrelevant it is to me to know what the thoughts or writings of racist despots were throughout history. It is far more relevant to me to study their actions - all of which were deplorable. One of the hallmarks of despots and men of evil is to say virtually anything - as Hitler clearly did - to manipulate people. The more you engage in "reading their mind" the more danger you risk to your own psyche. He stood for hate and destruction. Study something else.
