Spiegel Online has a general introduction to the goals and activities of the archetypal Islamist infiltration group, the Muslim Brotherhood—as neo-pseudo-realist members of our own government promote the foolhardy idea of “engaging” them: Dancing with the Devil: Charting the Rise of the Muslim Brotherhood.

The average member of the Muslim Brotherhood isn’t a rabble-rouser, either — he’s a doctor, pharmacist, teacher or lawyer. He wears Western trousers and shirts, not the ankle-long dishdashah garment traditionally worn by Arab men. He’s middle class — and he’s filled with rage. Rage over what he sees as the close cooperation between his government and the hopelessly corrupted West. Kept from pursuing his political aims, he is often a functionary amonst his contemporaries in Arab professional associations for doctors, engineers and attorneys.
