Don't be a fool, don't be a tough guy: Trump's bizarre letter to Turkish president

US President Donald Trump warned Turkish President Tayyip Erdogan in a letter about Turkey's incursion into Syria, "Don't be a tough guy" and "Don't be a fool!"

The October 9 letter was released by the White House on Wednesday as Trump battled to control the political damage following his decision to pull US troops out of northern Syria, clearing the way for the Turkish incursion against America's Kurdish allies.
