> So anybody that will follow, regardless of the person's policies won't matter fully, as that person itself will be replaced 4-8 years later.

That is the fundamental problem. The only way out, is to make changes to the constitution to specifically prohibit the executive branch from having any of this power to arbitrarily change things on a whim. That is the only way international peer could in the future trust an agreement made with the USA.

As long as the US feels it is ok to sign an agreement and immediately violate it, nobody in their right mind will bother to negotiate any future agreements. Which is not a good state to be in.

It's not only the power structure, it's also the flawed democracy that allows gerrymandering and can only have 2 parties. It's the oligarch controlled media. It's the legalised corruption.

Winner-takes-all democracies do tend to have only 2 parties.

Very few “democracies”—a term that is more strained the more the structure of the political system structurally disenfranchises rather than represents views in the electorate—are as winner-take-all as the US, combining a strong Presidential system with FPTP voting, and basically none of any significance has as strong of a duopoly as the US.

Canada typically elects 5 parties, though the Greens, NDP, and Bloc are typically sub-50 in a 338 seat house.

That won't solve anything. Congress already has this power they just abdicated it to the Executive. The only fix is better voters electing better people into Congress. -- good luck with both of those. The US is cooked.

No, it’s not good enough, you need a better system. Like in Switzerland

The Los Angeles metropolitan area has more people that Switzerland.

Population aside, there's no system that fixes what's broken in the US in the 21st century.

Trump, sadly, is the symptom of deeper structural ills that have been building in America for decades.

Congress moves a lot slower, though. Congress isn't going to change tariffs every 24 hours. It takes a lot longer to get anything through Congress.

I mean, you still have the "every 4 years", or worse, "every few months". It's not at the pace that Trump changes things, though.

Trump is using a few very specific laws. Congress could replace them if it were functional, and not ossified by Senate rules sometime allowing even 1/3 + 1 vote bloc a blocking veto.
