As Assad’s army weakens, rebels and analysts warn, it is also becoming more extreme in its fight for survival. And two of the grimmest scenarios observers have long feared—that Islamic extremism could come to dominate the rebel fight, and that Assad could decide to attack with chemical weapons—now look more likely than ever to take hold. Many Sunni soldiers have left the military’s ranks, leaving behind a core of dedicated troops, most of them Alawites like Assad. Though the sect makes up a relatively small proportion of the Syrian population—around 12 percent—it has dominated the country’s political machine for decades, and Assad has painted himself as the protector of the Alawites, along with other minorities such as Christians, Druze, and Ismailis. Now, after months in which Assad’s forces have leveled cities—and during which more than 40,000 people have died, according to activist groups—many loyalist troops feel their backs against the wall. “They know that the people on the ground know who they are,” says Khalil, who finally escaped to Turkey this fall, “and they know that justice will be brought” if the rebels prevail. “Their support for the regime is getting stronger and stronger. They know they have to fight to the end.”
