U.S. air strikes and aid deliveries to Iraq will continue as long as necessary, but U.S. airstrikes have already destroyed weapons the militants of the Islamic State of Iraq and al-Sham Islamist could have used to launch new attacks, President Barack Obama said Saturday. "I don't think we're going to solve this problem in weeks," Obama said. "This is going to be a long-term project." Obama stressed that "we will not have troops again in Iraq," but he said he was determined to prevent "an act of genocide" against the minorities stranded on a mountaintop. “We feel confident we can prevent ISIS from going up the mountain and slaughtering the people who are there," he said.
