“It would be announcing to the world that he failed.“
No it wouldn’t. Trump isn’t in control of the assholes of the world. If no one wants to play there anymore or attend there anymore, cancel the 250 mil upgrade and use the building or land for something else or sell it.
Uh, not a good look. It would then be that Trump destroyed, shutdown, cancelled, screwed up, sold, etc. the living memorial to President John F. Kennedy. Not a good idea.
