Civil War in Iraq

It appears that the Kurds have been busy inserting thousands of militia members into Iraqi army forces, especially in Northern Iraq. They are laying the groundwork to take back the city of Kirkuk along with its oil fields. Kirkuk was a Kudish city before Saddam drove the Kurds from the city and paid arabs to settle in the city. The Peshmerga militia are an awesome military force that has been fighting since Gulf War I. If the Kurds pull off making an independent Kurdistan, does this mean war with Turkey? Then whose side would we be on?
