Nobody's really sidled up to the Iraqi Kurds because (a) the leadership is a slippery bunch and (b) Iraqi Kurdistan is surrounded by Iraq, Syria, Iran and Turkey. Can't get to it without the consent of one of its hostile neighbors (hostile to us or hostile to Iraqi Kurdistan). Same problem we have with Afghanistan.
Ergo, it sounds like a great place for an Israeli re-fueling stop on the way to and from Iran...
