Kurdish Peshmerga soldiers man a checkpoint in Kirkuk, 250 km (155 miles) north of Baghdad June 29, 2011. Iraq’s Kurds may be split on everything from party politics to how to manage their region’s oil wealth, but most agree on one thing: They need U.S. troops to stay to help preserve the peace. More than eight years after the U.S. invasion, Iraqis are debating whether to ask American troops to stay on past a planned withdrawal, a sensitive question that is testing its fragile power-sharing government. Kurdistan is a potential flashpoint for tensions among ethnic Kurds, Turkmen and Iraqi Arabs, and most of its residents say U.S. troops should remain after the end of this year to keep apart rival groups making claims on the oil-wealthy territory.
