When Donald Trump was sworn in as US president for a second time in January, he made a promise. "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."

But how much progress is the self-styled "world's best peacemaker" really making? Is Trump turning the world into a safer, or a more dangerous, place?

There are many angles to the answer.

It is difficult to ignore the reality on the ground in perhaps the world's two most prominent conflicts.
