That’s being an alarmist to the point of absurdity.
Trump can say a lot of things. He can say he’ll leave NATO. He can say he’ll stop sending aid to Ukraine.
He can say whatever he wants, and I have no doubt the idiot actually believes it. After all, he said he was going to build a wall and make Mexico pay for it. He Said he was going to deport all DACA child. Hell, if I remember correctly, he said during the last campaign that he was going to leave NATO as well unless they fucking paid him, like it’s some sort of protection racket.
Despite the recent SC ruling, and despite four years of failing to actually do anything he said he could do, he still believes he’s a god-king. But with the exception of a presidential decree, which can be blocked by congress; nothing he’s fucking babbling about can just “be done” on his word. It has to pass Congress and the Senate, which will, despite the eventual winner of the presidency, remain close enough in seats for cooler heads to stop his bullshit. There are enough republicans, even in a Trump administration, that would never dream of fucking up that much.
The point is, Trump is a fucking idiot. And while the supreme court has made him effectively immune to criminal prosecution, his ability to do almost anything without eventually bumping up against the actual adults in the room is still pretty limited.
If he actually had the power to do what he says he can, he would have done it in his first term. But even in a party of of racists and MAGA, there are enough adults to keep him distracted with colouring books.
