Trump — angry, unhinged, petulant, impulsive — ventures overseas tomorrow on a trip to Israel, Saudi Arabia and the Vatican, followed by meetings in Belgium and Italy (with the Group of 7). Trump reportedly is “dreading” his trip. No wonder. This is a man who retreats to one of his resorts virtually every weekend and who had to fly home for the night during the presidential campaign. He clings to the familiar, where his ego will not be bruised, where sycophants surround him and where he feels like the big man on campus.
