WASHINGTON     -     President Donald Trump lashed out Wednesday over sharp bipartisan criticism of his decision to pull back U.S. troops from northeastern Syria, saying he is focused on the “BIG PICTURE” that does not include American involvement in “stupid endless wars” in the Middle East. “Fighting between various groups that has been going on for hundreds of years. USA should never have been in Middle East,” Trump said in a series of morning tweets. “The stupid endless wars, for us, are ending!” Sen. Lindsey Graham, R-S.C., a close Trump ally, stepped up his criticism of the president Wednesday, telling “Fox & Friends” that if Trump “follows through with this, it would be the biggest mistake of his presidency.” “I hope he’s right. I don’t think so,” Graham said, comparing Trump’s views to the “pre-9/11 mentality that paved the way for 9/11.” Trump defended his unpopular decision, arguing on Twitter that “GOING INTO THE MIDDLE EAST IS THE WORST DECISION EVER MADE IN THE HISTORY OF OUR COUNTRY!” He said the U.S. went to war under a “false & now disproven premise, WEAPONS OF MASS DESTRUCTION. There were NONE!” Trump said he is “slowly & carefully” bringing home “our great soldiers & military,” in line with his campaign promise to do so. He added: “Our focus is on the BIG PICTURE! THE USA IS GREATER THAN EVER BEFORE!” But the U.S. military has kept a decades-long focus on the Middle East as part of a strategy of stopping or minimizing security threats before they spread to American and allied shores.
