The footnote, unfortunately, applies to several pages of text so it is difficult to examine what the specific source was for this last paragraph. But for those who want to try:
This doesn't mean that Hitler was influenced by the Mufti in any way for his own genocidal agenda, but it does show that the Mufti did not merely want to get rid of Zionists from Palestine but to eliminate Jews from the planet - and that this desire may very well have pre-dated the rise of Nazism.
Based on what we know about how he incited Arabs to murder Jews in Palestine, it is not far-fetched.
