The irony is that western free nations owe their safety to America’s military, and by extension this sacrifice of the American people, if you follow the post’s logic
Name three nations the US has couped to replace their democratically elected leader with a corrupt autocrat that sold gladly his people to US interest in exchange of power.
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.
This trend starting to buck has provided more military engineering jobs than any bullshit the US military has ordered in decades. Come on Europe, get afraid. Buy some more weapons. Heh.
