The first few days of Donald Trump's first trip abroad as president has revealed something troubling about him: he is weak, out of shape and easily exhausted. He has already cancelled several events on his agenda, which was already designed to allow some downtime between events, and his staff attributes the cancellations to exhaustion.
Donald Trump appears to be not only mentally unfit for his job. His performance in Saudi Arabia indicates that he is also physically weak, unfit to travel and unfit to be the President.
