There is a considerable amount of discussion in conservative circles comparing radical Islamic fundamentalists to Nazis. While this comparison is probably a bit hyperbolistic, there is more credence to this line of thought than most people know.
Amin al-Husseini was the leading Islamic radical of the forties. He was a major player in the fight against the idea of a Jewish state. Yasser Arafat considered him a "hero" and fought under him. Al-Husseini spent the entire length of World War II in Berlin as an honored guest of the Nazis.
While this is only one Arab extremist, it does reveal an interesting and too little-known link between the Islamic radicals of today and the Nazis of yesterday.
