When he wasn't busy hitting on French president Emmanuel Macron's wife, he took in the annual Bastille Day parade, which featured tanks and fighter jets and all sorts of other awesome military stuff. Between this and his impressive handshake mindgames, Macron seems to think he has Trump all figured out.
This had been put right in July when Mr Trump visited Paris.
The most benign reason for a procession is the one Trump wants to emulate, marking a national holiday a la France's Bastille Day. It was two hours on the button, and it was military might.
"We're spending this year 700 billion, more than we've ever spent, on the military, which is good news for you 'cause we're friends", Trump told Macron.
"It was a tremendous thing, and to a large extent because of what I have seen, we may do that on July 4 down Pennsylvania Avenue in Washington", the USA president said.
"I came back and one of my early calls were, I think we are going to have to start looking at that ourselves", Trump told Macron during a meeting in NY on September 18. I don't know, we're going to have to try to top it, but we had a lot of planes going over.

The UN Security Council on Wednesday called on Myanmar to end the violence following a close-door meeting. Guterres said many women and children were arriving in Bangladesh "hungry and malnourished".
Washington already holds quite a few parades, including some with military participation that are held on Memorial Day and July 4.
"It was one of the greatest parades I have ever seen", Trump said.
"That military may come marching down Pennsylvania Avenue", he said then.
The day is a celebration of the country, in some ways similar to American Independence Day, but it begins with the world's oldest and largest military parade. But we had a lot of planes going over, and we had a lot of military might and it was really a lovely thing to see. Indeed, historically the United States has scorned the large military parades in nations like North Korea as signs of a childish nation obsessed with its own sense of military might. But it wasn't the first time Trump has talked about wanting a military parade in the streets of Washington.
