As far as the Mufti, he was a Palestinian patriot who tried, unsuccessfully, to prevent the European colonization of Palestine and the dispossession of the Christians and Muslims of Palestine by the European Jews and their British facilitators. He knew that if the British won the war his people would be expelled from Palestine and/or become subservient to the European colonists. It is exactly what happened. So, how can you fault him for trying to prevent a disaster for his people by supporting the enemies of Britain? Many other leaders of people seeking independence from Britain (or other allied powers) sought support from Germany.
I don't know that "patriot" is the right word.
ISLAMONAZI TERRORIST is a better description
Actually, for that particular person - you are finally right.
And that is what the PLO, hamas and fatah base their ideologies on, and how the Palestinians think in regards to Israel and the Jews
