Europe combined has two aircraft carriers. Maybe three? the US has five. We've also got B2's, F22's, F35's, and in the planes that can fly in the rain, F-15's, A-10's, and more A-10s. A-10's are the best planes. European nations are pretty much the only ones who have armor and air capabilities comparable to America, but we've still got shittons more of them (and they'd all be the same, unlike with Europe), and the aforementioned Nimitz class aircraft carriers, which can ruin the fuck out of anything.
