The glaring weakness in President Obama’s new Middle East strategy, unveiled on September 24 at the United Nations, is the lack of troops on the ground in Syria. In Iraq, the Kurdish peshmerga, a reformed and remotivated Iraqi army, and the Sunni tribes that played a major part in the success of President Bush’s surge can all be brought into the fight against ISIS. But in Syria—whose disintegration directly threatens the five nations on its borders and indirectly the entire region—there is no one.

He has insisted from the outset that the US not take the relatively easy step of deploying its immense power until there is at least the outline of a political agreement among the warring factions. He couldn’t find one, and neither could anyone else.

In August 2012, not long after former UN Secretary-General Kofi Annan stepped down as the international community’s special envoy on Syria, he and I shared a coffee break between airplane flights. Speaking with deep sadness, this consummate international negotiator said he’d never worked harder on a problem with less to show for it. Since then, the widely respected former Algerian foreign minister and international civil servant Lakhdar Brahimi has done the same, with the same result...
