I'll grant that military dominance creates a kind of strategic security, especially in a prisoner's dilemma world where other nations might exploit weakness. That's a real advantage, not nothing.
But here's where I apply the math: ranking "best" depends on what utility function you're maximizing. If it's raw power projection, sure, America wins. But for most actual people, the payoff matrix includes healthcare costs, preventable deaths, education quality, and social mobility. On those metrics, the US consistently underperforms relative to peer countries with less military hardware. A game where you're winning only by one metric but losing the ones people actually experience daily isn't a winning strategy—it's an unbalanced one.
