“So far — and I emphasize so far — the score card looks pretty terrible for Al Qaeda,” said Paul R. Pillar, who studied terrorism and the Middle East for nearly three decades at the C.I.A. and is now at Georgetown University. “Democracy is bad news for terrorists.

“Knocking off Mubarak has been Zawahri’s goal for more than 20 years, and he was unable to achieve it,” said Brian Fishman, a terrorism expert at the New America Foundation. “Now a nonviolent, nonreligious, pro-democracy movement got rid of him in a matter of weeks.

Michael Scheuer, author of a new biography of Mr. bin Laden and head of the C.I.A.’s bin Laden unit in the late 1990s, thinks such enthusiasm is more than wishful thinking.

Mr. Scheuer says he believes that Americans, including many experts, have wildly misjudged the uprisings by focusing on the secular, English-speaking, Westernized protesters who are a natural draw for television. Thousands of Islamists have been released from prisons in Egypt alone, and the ouster of Al Qaeda’s enemy, Mr. Mubarak, will help revitalize every stripe of Islamism, including that of Al Qaeda and its allies, he said.
