It all sounds like a grand conspiracy theory, but it’s not: The Grand Mufti of Jerusalem before and during the WWII years, Haj Amin El Husseini, a member of the Muslim Brotherhood (founded 1928) aligned with the German Nazis in 1937 and recruited Muslim SS units in Bosnia during the war.
This is the most detailed TV report I’ve seen on the subject of Islamist-Nazi connections. It’s in German, but subtitled in English.
There are a few takeaway points from all this. First, the jihad didn’t start in 2001 or 1993 or 1983 or even 1979. It goes back quite a bit farther, and isn’t a response to US policies. Second, the jihadis work with secular allies when it suits them. The grand mufti worked hand in glove with Hitler; they would work with anyone else who could provide whatever they believe they need to achieve their goals. Third, the Muslim Brotherhood isn’t dormant or dead — it boast about 20% of Egypt’s parliament, for one thing — and it and its various offshoots are still working toward the goal of global Muslim domination.
