"My proudest legacy will be that of a peacemaker and unifier," he told his audience at home and far beyond.

Then, a little more than a hundred days on, during his first foreign tour – which took him to three wealthy Arab states – he boasted that he was making good on that vow. "I will tell you that the world is a much safer place right now," he said in reference to Ukraine. "I think in two or three weeks we can have a much safer place."
