Trump is pulling on random economic levers that haven't been pulled before and then insider trading the chaos he creates. Why would he renegotiate? Well because pulling random levers and picking absurd numbers was never going to be sustainable, it was obvious from the start that none of this was long-game and the goal was a burst of short-term chaos.

Trump has been very clear that he wants easy money to flow and printer go brrr.
You don't get that with tariffs.
What you do get with tariffs is panic and an excuse to make printer go brrr.
Powell doesn't want to play ball so now Powell has got to go.

Trump heavily leans into the fact that people think he's an idiot maniac.

POTUS wouldn't do that only an idiot maniac would do such a thing; he's bluffing!

That logic doesn't work on Trump.
Nobody knows when he's bluffing.
I mean I can see what he's doing but apparently other people in the game can't risk it.

China was the only country to be like, "lol you literally can't do this for very long," and they came up with a long-game strategy just in case they needed one. That strategy is a helluva lot better than what Trump is doing, and he can see it.

His bluffs seem to go uncalled, because even if you call them there's still hell to pay in the short term.
