An incomplete list of authoritarian (by some definition) regimes historically and currently supported (by some definition) by the United States.

Here's an interview with a French fighter with the YPG in Syria. He contradicts himself twice (Amnesty is wrong about villages being razed by YPG... they are only razed for strategic reasons; we don't need imperialist help to defeat IS... NATO air strikes are key to our offensive), but that helps it sound less like a pure propaganda piece.

I've read interviews with a few other fighters, and this guy is definitely the most political (and optimistic). He's fighting in a communist unit, but I wonder how many of the Kurdish fighters overall hold communism to be such an important aspect of the struggle for Rojava.
