Your military spending for 1.5 trillion dollars on F35 is truly admirable, but this fighter is still not ready. In many cases NATO countries are forced to buy US produced weapons because of "compatibility".
Even if european countries spend 3% of their GDP on defence like in the cold war all that money would be spend on soldiers that can defend and very little on those that can attack. Not nearly enough logistics!
The US not needing defence can spend on offensive capabilities instead. This it does, plus scale benefits mean that the US is the undisputed winner in any war.
Mining tunnels is cheap compared to a real military. Pax Americana means they, like all european countries, don't spend a fraction of what we spend on defense.
