The sense of betrayal among nominally pro-Western factions in the opposition has grown intensely in recent days.
In the northern Syrian province of Idlib, a rebel stronghold, one commander said that the agreement Saturday proved that the United States no longer cared about helping Syrians and was leaving them at the mercy of a government backed by powerful allies in Russia and Iran.
Maysara, a commander of a battalion in Saraqeb, said in an interview that he had paid little attention to the diplomacy Saturday.
“I don’t care about deals anymore,” he said in an interview. “The Americans found a way out of the strike.”
He added: “The Russians did what they want. The Americans lied, and believed their own lie — the U.S. doesn’t want democracy in Syria. Now I have doubts about the U.S. capacities, their military and intelligence capacities. The Iranian capacity is much stronger, I guess.”
