Senior White House and administration officials tell me Trump’s national security adviser, General H.R. McMaster, has been quietly pressing his colleagues to question the underlying assumptions of a draft war plan against the Islamic State that would maintain only a light U.S. ground troop presence in Syria. McMaster’s critics inside the administration say he wants to send tens of thousands of ground troops to the Euphrates River Valley.
The White House and administration officials say Secretary of Defense James Mattis, Chairman of the Joint Chiefs of Staff Joseph Dunford and General Joseph Votel, who is in charge of U.S. Central Command, oppose sending more conventional forces into Syria. Meanwhile, White House senior strategist Stephen Bannon has derided McMaster to his colleagues as trying to start a new Iraq War, according to these sources.
