It's kinda like how zionists are learning their ideology is so toxic that the best thing you can do to sabotage political obstacles is to inflate Israel's interactions on the global stage. This was attempted against Burkina Faso recently, however I don't think it was very effective.
I think either Trump himself or one of his handlers, know that if he speaks about North Korea, Libs will just thoughtlessly parrot that the DPRK is a dystopian wasteland. At a time where it's becoming more impossible to maintain that image of the DPRK, the US ruling elite are using the spectacle of their political theater to obfuscate the truth as long as possible.
