Trump craved a grand ceremony another chance for him to declare himself unwanted Messiah who ended (in his words)a needless war.

He cares little for the cost, indifferent to who steps aside or what is sacrificed, as long as history grants him extra pages.

It’s not just reckless but the mark of a bully grasping at the edge of relevance.
