I feel like I have a general understanding of Trump's ideology so I tend to dismiss as hyperbole claims that he'll do something that blatantly goes against what I understand him to believe in.

Trump isn't quite an isolationist, but he's skeptical of international entanglements and foreign wars, on that part he and Tulsi see eye to eye. I just can't see him committing to what would almost certainly be another boots on the ground middle eastern bloodbath boondoggle. And given his views on mass migration, would he really want to displace another 2 million Arabs?

Likewise I think he's entirely serious about taking back the Panama Canal and willing to do it by force if he has to, because he sees a critical US strategic interest in keeping it out of China's hands, fairly serious about buying Greenland if he can get them to sell it but also willing to just buy mineral exploration rights and declare victory if that's the best deal he can get, because, again, his main interest here is in competing with China, and entirely joking about annexing Canada because, obviously, they'd never agree to that and doing it by force would be unthinkable. He's just trying to get under Trudeau's skin there.

Trump will threaten a US base in Gaza to make Egypt, Jordan, UAE, etc fall in line, and then take nominal control of the strip but in practice let regional states put forth plans for rebuilding and governing it and go with whichever one he and Netanyahu like.
