Donald Trump accused his Republican presidential rivals on Friday night of wanting to "start World War III over Syria," and suggested that the United States should instead let Russia deal with the problem. Trump has recently faced criticism for not providing details on what sort of foreign policy positions he would take as president. That lack of specifics is purposeful and strategic, Trump said during a 50-minute speech at the Great State Fair of Oklahoma on Friday night. He said Republicans who publicly share their strategic foreign policy plans are "crazy."
