While you have a point here, I think you’re completely missing the original. Pax Americana is a thing, but to your point it definitely comes at a price.

The benefits the grandparent commenter pointed out aggregate to North America, Western Europe and Oceania, while the costs you point out are imposed elsewhere.

What does that have to do with their point though? They’re saying that the rest of the West enjoys their prosperity because of the American military, and I don’t think they’re wrong. The coups and corruption elsewhere around the world are what enabled the prosperity.
