The money spent by the US on defence for the actual utility provided is WAY WAY WAY out of line by an order of magnitude. Most of the money is simply wasted. And in terms of "defence," all a country really needs is nukes and you will never be invaded again. All the extra shit like 100s of overpriced F35, stealth destroyers etc, are all wasted money, better spent on things adding social cohesion or a more education populace.
