Let's hold this comment until after the mid-terms. The biggest thing Americans can do to stop Trump's war mongering would be at the ballot box. Protesting is one thing, but actively voting in people with power to stop POTUS would be the most direct action they can take.

The majority of people don’t really care about the world, their country, etc.

They just care that they have what they need, that they don’t struggle too much in life.

In the US people will vote for whoever will make their life easier. To some degree there is morality/ethics/ideology but that’s usually grounded in something that effects you day-to-day

Examples from republicans: Keep out the immigrants or you won’t have a job. You don’t want trans people in the bathroom with your kid. Democrats are socialists which is morally repugnant (and will raise your taxes!)

From dems: republicans are trying to control women (reproductive rights), republicans will cut social programs, etc.

Nobody _really_ cares about wars in Iran, Ukraine, Gaza, etc aside from it effecting them at home.

(Really caring would involve donating, protesting, volunteering, etc — plenty of people talk/have opinions)
