Majed al-Muhammad, the commander of a Syrian antigovernment fighting group, slammed his hand on his desk. "Doesn't America have satellites?" he asked, almost shouting. "Can't it see what is happening?"
A retired Syrian Army medic, Mr. Muhammad had reached the rank of sergeant major in the military he now fights against. He said he had never been a member of a party, and loathed jihadists and terrorists.
But he offered a warning to the West now commonly heard among fighters seeking the overthrow of President Bashar al-Assad: The Syrian people are being radicalized by a combination of a grinding conflict and their belief that they have been abandoned by a watching world.
