The Kurds were more or less allies in the Gulf war. So yeah, they were not Moslem enough apparently.
They are good fighters as evidenced recently, but in their History, they also claim Saladin.
Kurds exist in northern Iraq, Southern Turkey and Syria I think. If numbers are large enough, they threaten all these countries land mass. I do know they would like and in my opinion, deserve their own territory. That is the threat. Maybe a result of master planning after WWII? I do not know.
