"If there's four Vietcong in a village with knives and punji sticks, we'll bring in a B-52. And I think, sometimes we need to learn to fight smarter instead of to fight richer. And this is what I mean, you know, education, "oh, education's expensive;" no it's not, books are cheap, (the) internet's cheap, we can fight smarter, we can learn. So, that's where resource-to-kill-ratio comes from."
