You're focused on the wrong boogyman. We spend obscene amounts of money on military power and soft power, yes. It benefits some people outside the US, but it benefits us the most geopolitically. We should spend less, or at least not continually increase the amount, and put money into programs that help people, yes.

Isolationism and xenophobia aren't as nice as they sound to some on paper. They would not improve the condition of our country's people; in fact, they'd likely worsen many of America's ills… see Brexit as an example.

Instead of focusing on what political leaders want you to focus on—arbitrary large numbers you have no influence on or control over—maybe try understanding the world's bigger picture, the benefits and harms of an international economy, what chess pieces are on the board and why. Perhaps most importantly, focus on participating in your local government (city, county, state; not federal) to advocate for issues, or at least vote for like-minded leaders.

There are no quick fixes in such an extremely complex and interdependent system, unfortunately. Not ideal, but it is what it is.
