Trouble then, as now, is the various Kurdish factions couldn't agree on anything. It was like herding cats, sort of like today's GOP.
Communist Kurds in the north, always fighting Turkish forces, and more normal Kurds in the south who are always fighting Arabs and Arab terrorists. There’s probably more than that, but those were the two groups I learned about over there.
Also, I would LOVE for these ISIS clowns to go up against the Peshmerga. That would bring their campaign to a very sudden and violent end.
