Nazi racial ideology posited that all non-Europeans were inferior to Aryans, but since they couldn't blend in as easily with "real" Aryans, sub-Saharan Africans, Arabs, and East Asians were much less dangerous to the Aryan gene pool and didn't need to be exterminated, as Jews, Roma, and most Slavs were.

The attitude toward Indo-Iranians is rather singular, though, because they were regarded as Aryans, but not as pure and superior as the Nordic people of Germany, England, and Scandinavia. Nazi racial ideology was quite popular among elites in Iran, many of whom already had negative views of Arabs, Jews, and Turks, but I'm not sure about how it was received in India.
