TEXT: Iraq US-5 In this Friday, Oct. 21, 2016 photo, U.S. and Iraqi forces work together at a joint base, on the outskirts of Mosul, Iraq. Reverberations from President Donald Trump's travel ban and other stances are threatening to undermine future U.S.-Iraqi security cooperation, rattling a key alliance that over the past two years has slowly beaten back the Islamic State group. Iraq's prime minister, Haider al-Abadi, has sought to contain public anger sparked by the ban and by Trump's repeated statements that the Americans should have taken Iraq's oil, as well as his hard line against Iran, a close ally of Baghdad.
