At this point I'm suspicious of any viewpoint that posits Trump as a president/person with an agenda. I'm pretty baffled by the serious policy "experts" analyzing his actions and trying to determine cause and effect.
It's pretty clear to me he's a demented old man reading off the teleprompter. I'm sure he finds all these duties of presidency pretty hard and tiring on his body and mind. I feel that all he really thinks about is golfing, his estate business, increasing his wealth through other means like crypto scams and the like, and always getting more attention which he desperately craves.
The White House administration, intelligence services and the Pentagon collectively decide what to do, be that invading Greenland, Venezuela or the like. Trump has occasional stupid demands as well, like the FIFA Peace Prize which I'm sure the admin staff find very hilarious but comply regardless to make his little boy wishes happen to preserve the status quo.
Even more spicy takes: The only reason the societal divide exists in the US today is Meta. Facebook and Instagram. When people are exposed to entirely separate spheres of content for hours a day every day their opinion changes slowly but surely and there's pretty much no escaping it.
I don't use any social media besides HN (which no doubt also does this covert influencing). I can spot a person's social media app of choice is in 5 minutes. They literally change a person's character and the way they speak.
