Stephen Farnsworth, a political scientist at the University of Mary Washington, said public opinion in the U.S. “tends to be pretty isolationist,” and Trump himself campaigned as a critic of “endless wars.”
While presidents sometimes see a short-term spike in approval ratings after the start of military action, “that doesn’t tend to last very long,” Farnsworth said. With the election months away, he said, “there is no way to predict what the world is going to look like in October.”
