This is not how the world works. We are about to enter a worldwide recession because Donald Trump hired either a BA in Economics who didn't know his qualitative analysis, or a journalism major who is running PR defense for Trump using ChatGPT.
You don't enter a TPP agreement with other countries because they outnumber you in a bloc and, therefore, can coalition-build against you. This is why the bilateral trade is better for heavyweights like your Chinas, US, and Russias size countries, vs, for example, smaller countries like Malaysia. You can bully people more in those talks like what China did to Singapore, for example. It's not fun, and I wish we didn't do it to say Lestho as a human being, but that's a valid, if unethical way to do it, but not always.
What you don't do is implement policy via algebraic equations that assume countries will sit there and do nothing, because most won't. Some of his ideas are good, I want to shoot down Russian ICBMs so a US Iron Dome equivant like 'golden dome' is a good idea, and no, China won't start a nuclear war because they comprise 1/7 to 1/8 of humanity, and thus many more people would die in China vs the US, which is why the US nukes have escalation dominance in MAD granted just because the US has more medium sized towns than Russia, and population is more spread out than China doesn't make nuclear war a great idea either, but the calculus holds. Thank all that is holy, he didn't cancel the F-47, that was such a bad move by the Air Force/Navy to even propose that.
I don't care if he gets the world to hate us if he gives us an edge in geopolitics and reverses the US GDP as a portion of the world's GDP. A growing portion of the world has the internet, and will get jealous of the US evenutally if they aren't right now unless they get a green card like how a hourly employee is jealous of a salary employee who is jealous of a millionaire who is jealous of the multi-millionaire who is jealous of the billionaire who is jealous of the mulit-billionaire.
Edit: This isn't how you make America great again.
