Sometimes you gotta go with the symbol you got.

President Kennedy initiated the U.S. Moon landing project, which culminated in 1969 with the famous landing where the astronauts got to talk publicly with President...Richard Nixon. I wasn't crazy about it, but it was the way it was, and represented if nothing else, continuity.

I take Al's comment that for the duration of the commemorations, the Current Occupant (Trump) represents an ally over generations. The rest of the time our currently failing and bemused and confused democracies can do as they wilt,,,which of course is watch "Game of Thrones."
