Retired Marine general says Trump has 'blood' on his hands for 'abandoning' Kurdish allies

President Trump made a grave mistake by pulling back troops in Syria last week, allowing Turkey to launch a military offensive against the Kurds, a retired four-star Marine general told CNN on Sunday.

"There is blood on Trump's hands for abandoning our Kurdish allies," Gen. John Allen said. The Kurdish-led Syrian Democratic Forces worked with the United States for several years to fight the Islamic State, and controls the northeastern border area. Since the Turkish assault began last week, video footage has emerged purportedly showing Turkish-backed militia fighters shooting Kurdish prisoners. This, Allen said, is a "full-blown ethnic cleansing."

The Kurds oversee prisons holding thousands of ISIS fighters, their families, and supporters, and hundreds escaped during fighting over the weekend. Allen — the former commander of American forces in Afghanistan and former special presidential envoy for the Global Coalition to Counter ISIS during the Obama administration — said this chaos was "completely foreseeable" and "what happens when Trump follows his instincts and because of his alignment with autocrats."

Allen is also unmoved by Trump's approval of $50 million in aid to Syria. This gesture rings "hollow," he said, and there's no way to say if the money will go where it should. "Who's going to administer it and for whom?" Allen said. "Hundreds of thousands are fleeing and the relief agencies are on the move."
