Op-edPresident Trump called for the destruction of terrorists, but he talked of them as if they were foreign invaders to be driven out of the swamp, not products of it. Like the man who only has a hammer and therefore thinks every problem is a nail, Mr. Trump believes that the Middle East's problems can be solved with terrific "deals." The Saudis, eager to buy weapons and counter Iran, are all too eager to encourage this view. What alligator doesn't want sharper teeth?
