Is it worth diversifying and investing in any other countries or is sticking with the US the best bet?

I’ve been thinking lately that while I am diversified (s&p 500, bonds, 401k with stock index funds) it’s all purely in the American market.

Well, what if the US fails?

And I’ve done research and the other big players either don’t have markets to actually invest in via traditional means or are just are way more risky.

The first one is obviously china. The problem with them is the major demographic crisis (seriously, do a little research about it, it’s insane and they’ll have double the amount of old people compared to young soon) and the fact that they LIE an outrageous amount, and also steal IPs and designs a crazy amount.

The CCPs power is outrageous and practically owns everything over there. I’ll pass.

Next is the EU. I genuinely can’t remember the last European product I’ve bought. Other then adidas, I can think of a few companies (most are german). Mercedes, adidas, BMW, and maybe some energy companies. They own some big fashion brands like LV

But honestly? I’d rather invest in Nike, Tesla, etc. every one of those companies has an American counterpart.

They are having issues with stagnation and with their very regulation heavy economy and their big demographic issues, I’d just rather invest in the US.

Japan? Don’t get me started on Japan. What a joke of a economy with their stagnation.

I’d love to hear your guys thoughts on this.
