U.S. President Donald Trump on Monday threatened to "totally destroy and obliterate" the Turkish economy if Turkey took any action he considered "off-limits" following his decision to withdraw American forces from northeastern Syria.

The withdrawal, announced by the White House late Sunday, was swiftly condemned by a bipartisan group of lawmakers over concerns that it could open the way for a Turkish strike on Kurdish-led forces long allied with Washington.

"As I have stated strongly before, and just to reiterate, if Turkey does anything that I, in my great and unmatched wisdom, consider to be off limits, I will totally destroy and obliterate the Economy of Turkey (I've done before!)" Trump tweeted.
