From New York Times Magazine:

I found a 26-year-old American civilian named Clay Lawton standing alone, just outside the village. Square-jawed, with large eyes and bright teeth, he was a volunteer freedom fighter with the local militia. ‘‘I’m from Rhode Island,’’ he said. ‘‘You know it? Most people confuse it with Staten Island or Long Island.’’

Lawton first heard about ISIS on ‘‘The Daily Show With Jon Stewart.’’ At the time, he was lounging around Key West, driving tour boats from island to island, going to parties, talking to girls. Three months later, he ran out of things to do and bought a ticket home. He lived with his parents and took a job painting houses, thinking he would start a career as a carpenter. After high school, he spent a couple of years in the Army but never deployed. He always wished he had. When a friend from boot camp sent Lawton an email full of links to videos made by the Islamic State — the execution of James Foley, clips from the day ISIS executed 250 Syrian soldiers in the desert — Lawton looked up ‘‘how to fight ISIS’’ on his lunch break.

A Facebook page called the Lions of Rojava was recruiting foreign volunteers. It was affiliated with the People’s Protection Units, known by the Kurdish abbreviation Y.P.G., the military arm of a faction that since 2012 has controlled a sweep of land between the Islamic State’s territory in northern Syria and Turkey. Rojava, as the Kurds call it, is a place that didn’t exist until a few years ago, when civil war in Syria opened up a front for Kurdish nationalism.
