For the most part you have exactly the same levers to pull at people in the United States, sans voting in elections, but most Americans don’t even do that, and some specific things that require a physical presence, like protesting at the White House specifically.

Setting aside that you can do things about this and effect change, caring about something isn’t the same as being able to affect that thing, so your reasoning “people outside the US don’t care because they can’t do anything about it” is a bit off.

You can prepare for negative second-order effects. Perhaps not every individual article is helpful for that but it’s hard to say they are not in aggregate.
