What if Turkey attacks the Kurds?

Sharon Behn of the Washington Times reports that the Kurds demand U.S. defense from the attacks that may come their way from Turkey, already enraged by the Democrats' resolution condemning the Armenian slaughter as a genocide.

Kurdish leaders said yesterday the United States is obliged by a U.N. resolution to defend them in the event that Turkish forces invade northern Iraq in pursuit of members of a Kurdish rebel movement.
So, what should we do? Are we ready to go to war with our "important ally" Turkey? Or do we abandon the Kurds who've been more supportive of the U.S. than anyone else in the Region (with the possible exception of the Israelis).
