The fastest-growing al Qaeda operation is in Syria. Zawahiri ordered al Qaeda jihadists from around the world to go to Syria last February. They carried out seven attacks in March, and at least 66 in June. Al Qaeda won’t take over the embattled country, but it will thrive in the civil war and chaos there—and use Syria as a base for attacks in Jordan, Turkey, and Lebanon.
