There are good Kurds and bad Kurds. The PKK is a terrorist group but the Kurds in Iraq that were victims of Hussein’s are friends of the United States and the ones we armed
There are also complex tribal and family ties, which, if you study Kurds and their society for the next twenty years, you may be able to write a book that will already be out of date by the time it reaches the bookstores. Same with Arabs, Balluchis and all the others. Leonard Cohen had it right, at least vis a vis the Middle East: “When you call me brother, forgive me if I ask you, just according to whose plan? When it all comes down to dust, I will kill you if I must and help you if I can. When it all comes down to dust, I will help you if I must, and kill you if I can.”
