The U.S. military is “not in Iraq to seize anybody’s oil”, Defense Secretary Jim Mattis said as he arrived for talks with Iraqi leaders on Monday, distancing himself from remarks by President Donald Trump. Mattis was the highest-ranking Trump administration official to visit Iraq since Trump irked Iraqis with a temporary ban on travel to the United States and for saying America should have seized Iraq’s oil after toppling Saddam Hussein in 2003.
