More Help for Syrian Rebels There was more horror in Syria over the weekend, where scores of bodies, most of them civilians, were discovered in a Damascus suburb. The victims are believed to have died in a weeklong offensive by forces loyal to President Bashar al-Assad, who seems to have no misgivings whatever about a slaughter, including the use of airstrikes and missiles, that has claimed more than 70,000 lives so far during two-and-a-half years of war. Long after Western governments predicted he would be gone, Mr. Assad is hanging on even as his country unravels, deepening sectarian divisions, expanding the fighting across borders and forcing an estimated one million Syrians to flee to neighboring countries. There are increasing fears about whether the country can hold together, whether the fighting will destabilize its neighbors and whether, when all is said and done, extremist groups with connections to Al Qaeda who have been among the best anti-Assad fighters will emerge on top. Eager to find ways to speed Mr. Assad's fall, or at least change his calculations, President Obama is edging, cautiously but appropriately, toward greater support for the rebels. Secretary of State John Kerry said on Sunday that Washington would double aid to the opposition's military wing by providing an additional $123 million in "nonlethal" assistance like body armor and night-vision goggles. Some $385 million in humanitarian aid had already been committed. The president has wisely resisted calls to supply American weapons and to intervene directly. He should continue to do so. Nevertheless, in recent months, the C.I.A. has helped Arab governments and Turkey airlift arms and equipment to the rebels and provided training. The agency also vetted rebel groups to ensure that only moderates receive those supplies. Such caution makes sense, not least because the administration itself is not unanimous on whether more aid is a good thing. Mr. Kerry sees opportunities in the opposition, while Gen. Martin Dempsey, the chairman of the Joint Chiefs of Staff, has warned of the risks of deeper involvement with opposition groups whose loyalties to the West, and a moderate course, are suspect. A weekend meeting in Istanbul of 11 countries committed to aiding the opposition sought to address some of those problems. Mr. Kerry said donor nations agreed to funnel all aid through the rebel military council to prevent it from falling into the hands of extremist groups. The rebels also renewed their promises to embrace minorities who have backed Mr. Assad, build a pluralistic government and forgo postwar reprisals. Meanwhile, the European Union on Monday eased sanctions to allow European importers to buy oil from the Syrian opposition, which controls some territory with oil deposits. This may have little practical effect given the country's battered infrastructure, but it could boost the opposition's credibility and finances. The European Union should think twice about letting its arms embargo expire because that could open the door to Britain and France providing the rebels with lethal aid. Assisting the rebels is not the whole answer. Mr. Obama and Europe should keep trying to persuade Russia to abandon its unconscionable support for Mr. Assad and to work cooperatively to stabilize the region.
