Reuters foreign affairs and national security editor John Walcott writes about the unrest and disarray building within the WH:

• "The clash between internationalists ... and advocates of an 'America First' approach has worn down foreign policy and intelligence professionals inside the government."
• "Secretary of State Rex Tillerson has told friends he will be lucky to last a year in his job, according to a friend, while two officials said national security adviser H.R. McMaster was frustrated by what he sees as disorganization and indiscipline on key policy issues inside the White House."
• Not a good sign: "R.C. Hammond, Tillerson's spokesman, denied Tillerson was considering leaving."
• "Senior national security officials said McMaster was dismayed that his recommendations, backed by his senior director for Russia, Fiona Hill, about taking a tough stance with ... Putin, had been ignored."
