[The Hill] McCain, a longtime advocate of arming Syrian rebels and removing Assad from power, also barbed Tillerson, who recently said whether Assad will stay in power "will be decided by the Syrian people." McCain called that remark "one of the more incredible statements I’ve ever heard," echoing a fiery statement he released previously."Syrian people cannot decide the fate of Assad or the future of their country when they are being slaughtered by Assad’s barrel bombs, Putin’s aircraft and Iran’s terrorist proxies," McCain said Thursday. "U.S. policy must reflect such basic facts."
Calling Assad "one of the great brutal dictators in history," McCain emphasized that leaving the Syrian president in power would contradict the United States’ duty to spread democracy throughout the world.
"These are war crimes on the scale ... almost unmatched since Nazi Germany or Pol Pot."
Although McCain expressed "confidence" in the Trump administration’s national security team, he lamented what he said was a lack of conviction in America’s policy toward the Syrian civil war.
"I don’t see any doctrine right now," he said.
