In 2015, Bush said that he does not support a further major commitment of U.S. troops in Iraq to fight the Islamic State of Iraq and the Levant (ISIS or ISIL), saying that such a deployment is not needed to defeat ISIS. He has not, however, ruled out such a deployment in the future. Bush favors building a new U.S. base in Iraq's al-Anbar province, and has said that some U.S. troops ought to be embedded with Iraqi armed forces to help train them and identify targets as joint terminal attack controllers (JTACs). Bush has not commented on adding to the approximately 3,500 U.S. troops in Iraq now.
