STANDING TALL:

With Erdogan on the line, Trump asked national security adviser John Bolton, who was listening in, why American troops remained in Syria if what the Turkish president was saying was true, according to the officials. Erdogan's point, Bolton was forced to admit, had been backed up by Mattis, Pompeo, U.S. special envoy for Syria Jim Jeffrey and special envoy for the anti-ISIS coalition Brett McGurk, who have said that IS retains only 1 percent of its territory, the officials said.

Bolton stressed, however, that the entire national security team agreed that victory over IS had to be enduring, which means more than taking away its territory.

Trump was not dissuaded, according to the officials, who said the president quickly capitulated by pledging to withdraw, shocking both Bolton and Erdogan.

Caught off guard, Erdogan cautioned Trump against a hasty withdrawal, according to one official. While Turkey has made incursions into Syria in the past, it does not have the necessary forces mobilized on the border to move in and hold the large swaths of northeastern Syria where U.S. troops are positioned, the official said.
