Historical facts  are fun...the Japanese / Chinese were made " honourary Aryans" for politicians cal reasons...but the Nuremberg Race Laws did not allow the "honourary" Aryans to marry and reproduce with true Aryans.

The Iranians were no limited by the Nuremberg Race Laws and could marry German Aryans...Iranians, being racially pure , were allowed to join the SS...there were no Chinese or Japanese in the SS.
