 It's changed the face of aggression. If you're an aggressor, if you've got Adolf Hitler impulses that line 2,000 tanks up and run over and steal some land that's not yours, it's just not going to work now. And there's no nukes involved. I mean, 40 years ago, they were talking about airburst nukes that would irradiate the tank crews and kill them inside the tank. But then you've started a nuclear war. There's no nuclear war anymore.
