The US does 40 percent of the world's military spending. It sells hardware and sends military aid. If you direct your memories back through the mists of time into earlier this afternoon, you guys have been sperging out because you thought the US might
not have sent a country military aid.
(protip: it did)
The US doesn't maintain its military for the sake of other nations, and it does not appear to me that
@Commodore said or meant that, either. What he means is that this huge imbalance of power has the effect of preventing conflagrations from breaking out. That's a lot of lives and property saved, around the world, on a yearly basis. Even if it is not exactly the point, it has been an effect noticed and utilized by people outside the US.
Europe for instance may be moving against the dollar, but what they are not doing is creating a vast anti-US military alliance and engaging it in an arms race. Instead, they are just sitting tight with the UN's hand in our back pocket, and redirecting their own budgets to health & pensions. A
post facto indication, through peoples' deeds, that the US military deters war and has a certain trust capital. It's good to have a president for once that isn't overly violent, too.
