THE BUSH administration has tolerated Egypt's brutal crackdown on domestic dissent and the broader reversal of its democratic spring of 2005 in part because President Hosni Mubarak argues that his adversaries are dangerous Islamic extremists. It's true that the largest opposition movement in Egypt is the Muslim Brotherhood; how dangerous it is can be debated.

He said the brutality he witnessed was the result of extremist Islamic teachings, in part by his own university, Al-Azhar, which he called "the other face of al-Qaeda." He compared the prophet Muhammad to Israel's Ariel Sharon. And he said Mr. Mubarak was a "symbol of tyranny."
