Obama pointed this out during the debate:
OBAMA: But I think Governor Romney maybe hasn’t spent enough time looking at how our military works. You mentioned the Navy, for example, and that we have fewer ships than we did in 1916. Well, Governor, we also have fewer horses and bayonets, because the nature of our military’s changed. We have these things called aircraft carriers, where planes land on them. We have these ships that go underwater, nuclear submarines.
And so the question is not a game of Battleship, where we’re counting slips. It’s what are our capabilities
Watch the clip:
In other words, 1,000 1940s-era fighter planes combined can’t do what one of today’s B-2 Stealth bomber can do, the same for Navy ships in 1917 versus today.
