There is no new world order.
What Trump and his mates are doing is essentially playing with the world stock markets for their own benefit. This will last a couple of years at most, once they've got what they can out of it they will stop playing this game and move to the next, crypto, oil, whatever.
What the world is doing wrong in my opinion is reacting exactly as they want, China retaliating and further devaluing orienatal markets was the perfect example. Trump and Musk must have been wetting themselves laughing when they saw that.
Other countries and markets are not reacting in such a kneejerk way and are planning to negotiate. This will still give Trump what he wants to a certain extent, because the markets have already reacted, but it will be a more tempered and measured gain for him and his team. Like any war, the negotiated settlement is the less painful than the absolute victory.
Trump is very clever and he will leave the White House significantly richer than he entered it, and it will be at our expense. All we can do is try to be almost as clever and limit it as much as possible and know that the next president is unlikely to continue with the policies which are simply self serving, and, again in my opinion, have no further political goals than personal financial gain.
Milei tried to be as clever in Argentina with his crypto scheme, and because he isn't as clever, made a great big balls up of it. Although he probably will still get away with it!
