The reason why we talk about USA way more than other countries are not what you seem to think.
Try getting on a news feed for a day and check the river of news, often very important, that are NOT reported in the USA because they're not important.
I have a serious problem with the obsession we have in Europe for example with American politics.
We live under this assumption that what happens in the USA shapes what happens everywhere else but that is only true to a much more limited extent than what coverage and media attention might suggest.
In fact for Europe I believe that what happens in China for example is right now way more important and impactful.
Not to mention Africa (check what's happening rn in Niger, for example).
Look the problem is simple. Every country is self-centered to an extent about its own topics, issues, and problems. USA is the only country that's absolutely and utterly convinced that when it comes to its own issues, than everyone else is not talking about anything else but that.
