President Trump says the US will pull back from military involvement in the Middle East and leave it to others "to figure the situation out". In a series of Twitter messages, the President defended his decision to withdraw US forces from Northern Syria to make way for Turkey to create a buffer zone south of their border. The planned military operation by Turkey would sweep away America's Kurdish allies near the Syrian border. Turkey's President Recep Tayyip Erdogan considers the Kurdish groups to be terrorists and says he will not give any timescale for millitary action. The BBC's diplomatic correspondent Paul Adams told Morning Report this could represent a significant shift in US policy, if it all happens as Mr Trump says it will.
