This is most certainly a must watch video. It explains how Hitler and one very influential Islamic leader, the Grand Mufti of Jerusalem, collaborated against the Jews.
I found this video at A Deeper Look. There you can find a collection of videos and slideshow resources about Islamic extremism, terrorism, and the Israel-Palestine conflict.
Actual file footage is shown throughout the 7.43 minute video. Some of ithe video is in German with English subtitles and other parts are in English. It ends rather abruptly but that doesnt take away from the information presented in the video. I think you just want to see more... It also briefly show how Hilter is still influencing the Arab world.
