President Donald Trump on Wednesday said the U.S. did not endorse Turkey’s military operation in northern Syria, a move he called a “bad idea.” Trump’s decision to withdraw U.S. troops from Syria has been met with bipartisan criticism. The president threatened Monday to “totally destroy and obliterate” Turkey’s economy if it took what he considered to be “off limits” actions. The iShares MSCI Turkey ETF TUR, -2.39% was down 2.55%, following the beginning of the Turkish military offensive.
