That's unlikely. Sovereign nations generally act in their own best interest. For a quite visual example, for most of the Ukrainian war, Ukraine worked as a key transit hub for a huge chunk of all Russian gas heading to the EU. Why? Because they assessed the billions of dollars they gained in transit fees as being more beneficial to themselves, and their war effort, than interrupting the flow would be.

Doing something self destructive to spite another country is often a sign of either incompetent leadership or of a country that's not truly sovereign - countries that end up with some major dependency (economic, military, or political) on another country can be compelled to act against their rational self interest.

So back to here, the effect of what Trump's doing is not particularly unique. The US has few, if any, allies and lots of countries that are simply nominally independent vassals. We say jump, and they only ask how high. But what he is doing that's particularly unique is making this entire charade 100% transparent and giving them absolutely 0 chance at saving face. I think he simply enjoys humiliating them, very possibly as a result of things that happened during the previous administration.

It will probably accelerate the shift to a multipolar world. I'm very much not a believer in the 5d chess stuff, but I would at least tease the possibility that this outcome might have been considered and not be seen as undesirable. If one considers the goal of solely advancing American interests, it's not clear that hegemony is beneficial. Hegemony entails endless wars and endless interventions around the world funded by endless debt. And as allies and enemies alike reach technological parity, it's becoming ever more dangerous.

And for what? How does this all positively affect the average American? In a purely transactional world, it's hard to see how America, in terms of the affects on Americans, would be worse off than in the current one where we expend just unimaginably massive amounts of resources trying to maintain hegemony.

Countries are already doing what is in their best interest, which is why all these "agreements" are essentially fake. Countries are simply saying nice things hoping to get keep tariffs low for as long as possible. But the actual plan, not even hidden, leaders from wester nations all over are saying it out loud, is to diversify trade.

Once trade is diversified, the US will be isolated naturally as it represents the least beneficial trade arrangement. Now, if MAGA is dethrowned somehow, sure, trade with the US will increase again, but the diversification you see happing now will be permanent. Things aren't going to go back to the way they were, the US has already given up it's spot as the economic leader of the west, and it's given up all its foreign soft-power, it's just a slow process to see it all play out.
