Dear Lord, do I feel old. Thanks!
Well, we developed the first atomic bombs in the early '40s - - that's a real long time ago - - with slide-rules. When I think about the technological revolution that has transpired since then, I simply cannot imagine that the atomic bomb is still the most sophisticated weapon in our arsenal. No way. Those things are technological dinosaurs, and we have had nearly 60 secret, well-funded years to come up with:
1. A way to stop them from being used against us, and
2. Far more potent weaponry.
