Except the US has only contempt for anything south of Texas. Perhaps "western countries" will be reduced to US and Canada.

Many countries in Latin America have better relations and more robust trade partnerships with China.

As for the EU, I think it will be great for it to shed its reliance on the US, and act more independently from it.

The US is talking about annexing Canada, so "western countries" means the USA, which if continuing down this path long enough will become a pariah

This always reminds me of the Fallout opening video.

Only if they do it by force.

Trump has already managed to completely destroy the US reputation within basically the entire continent¹. And he seems intent on creating a commercial war against all the countries here too.

1 - Do not capture and torture random people on the street if you want to maintain some goodwill. Even if you have reasons to capture them.

Yeah... I don't think goodwill was ever a very central part of the Monroe doctrine. Its imperial expansionism, plain n' simple. Embargo + pressure who you can, depose any governments that resist, threaten the rest into silent compliance.

Scary times.
