Friday's Camp David talks on Afghanistan appear to have ended without a final decision by President Trump on troop levels, as he continues to resist pressure from top cabinet officials to sign off on a massive escalation of the 16-year-old conflict with thousands of fresh troops.

Trump had initially delegated the decision to Defense Secretary James Mattis, but Mattis found a cap limiting his maximum deployment too restrictive. Now, Vice President Pence and National Security Adviser H.R. McMaster are also taking up the cause of large-scale escalation, pushing Trump to accept the recommendations of the commanders.

Pence and McMaster were at the Camp David meeting, but Blackwater founder Erik Prince, who has been pushing a "privatize the war" initiative, was blocked, apparently at the behest of McMaster. Trump aide Steve Bannon, another skeptic of military escalation, was sacked outright.
