So what took al-Qaeda so long to replace Osama bin Laden? It's been over six weeks since a U.S. Navy SEAL team killed the terrorist chief, and only now has al-Qaeda decided on his successor Dr. Ayman al-Zawahiri, an acerbic Egyptian physician who was bin Laden's longtime deputy.
Even for the likes of al-Qaeda, an organization not known for its warm and fuzzy side, al-Zawahiri has a reputation for obnoxiousness. One ex-militant describes al-Zawahiri, 60, as "sharp-tongued" and "arrogant." His scraggly beard, prayer callous on his forehead and thick glasses make him look more like an unpleasant and pious schoolmaster than a terrorist mastermind. Nevertheless, al-Zawahiri remains a force to be reckoned with. The Egyptian fully intends to continue waging bin Laden's war against the U.S. and its allies, his hatred sharpened by the fact that his wife and two children were killed by a U.S. air strike in October 2001 while fleeing across Afghanistan.
Despite the Egyptian's fulsome eulogy for his boss earlier this month, the take-charge deputy was often at odds with bin Laden. Hothaifa Abdullah Azzam, a Jordanian cleric who spent time in Peshawar, Pakistan, and who maintains communication with some fighters of al-Qaeda told TIME in Amman that by 2006, al-Zawahiri and his comrades were "isolating bin Laden with the excuse of protecting him." He adds, "Nobody I met liked al-Zawahiri, but he is the guy moving things." Azzam also says that bin Laden and al-Zawahiri quarreled in 2007 over the choice of a new military commander after the previous one was killed. "Al-Zawahiri got his way and bin Laden was not happy." The new commander is thought to be either Saif al-Adel, a former Egyptian commando, or a Libyan, Abu Yahya al-Libi.
Al-Zawahiri's abrasiveness is one factor to explain why he was not automatically picked to replace bin Laden by al-Qaeda's ruling council, the so-called General Command. Another is his lack of combat experience. A former surgeon and ideologue, al-Zawahiri has a reputation for leading from the rear. "He's called the 'Shadow Leader,'" says Azzam. Furthermore, a new, younger generation of combat-hardened jihadi leaders from Libya and Yemen are rising through the ranks, and their utterances on the Internet seem to have far greater impact than al-Zawahiri's oft-repeated rants against the Americans and the Jews.
Several weeks back, a few jihadi-militant websites claimed that the Egyptian al-Adel had been chosen as a "caretaker" chief, and it seemed that al-Zawahiri had been shoved aside. One Washington official who tracks al-Qaeda offered two scenarios to explain the need for a caretaker: either a succession battle was raging inside the terrorist group, or its commanders were too scattered after bin Laden's death to gather for a vote. Either way, says the official, "It underscores the fact that al-Zawahiri isn't well liked by the senior leaders or the foot soldiers."
Unlike bin Laden, who spent the past six years holed up behind the penitentiary-like walls of his Pakistan safe house, al-Zawahiri is a moving target. "His business cards are left all over the place," says South Asia expert Michael Semple, a fellow at Harvard's Kennedy School. By all accounts, the Egyptian has been moving around Pakistan's tribal borderlands and fleeing the predatory missiles of the drones.
Yet, even on the run, al-Zawahiri can't keep quiet. Since 2006, he has broadcast 22 anti-Western video sermons on the Internet, compared with a single appearance by his late boss. Earlier this month, in his first public response to bin Laden's death, al-Zawahiri proclaimed, "Today, and thanks be to God, America is not facing an individual or a group ... but a rebelling nation [a reference to the Muslim community] which has awoken from its sleep in a jihadist renaissance, challenging it wherever it is."
Al-Zawahiri is as deadly as he is elusive. Counterterrorism experts say that when bin Laden slipped into his Abbottabad villa, al-Zawahiri handled day-to-day operations for al-Qaeda and coordinated murderous attacks with the organization's Taliban allies. He roams inside a wide swath of Pakistan's mountainous border with Afghanistan, extending from Bajaur (where the widower may have married the daughter of a Pashtun chieftain) down to South Waziristan. This lawless region, says Semple, is "the world's greatest jihadi industrial park," from where al-Qaeda supplies "specialist services" to the various Pakistani and Afghan Taliban factions bent on committing spectacular suicide bombings and assassinations.
