The Kurd's have been basically under attack for freaking ever. Iran attacks them, Turkey attacks them, hell one of the reason we went into Iraq was becouse the Kurd's were being wiped out, including the use of gas on them. They have been our ally for a very long time in the region, even though we keep screwing them over. No surprise that they would want the US to wipe out Iran, and or. Everyone else in the region. That way, they may once again have their own country.
