War implies a contest; when you get to the point that contest is no longer involved and the outlook comes close to destruction of the enemy and suicide for ourselves-an outlook that neither side can ignore - then arguments as to the exact amount of available strength as compared to somebody else's are no longer the vital issues.

Nuclear fission. Here's the one-sentence case for nuclear power: It's the only carbon-free energy source that can reliably deliver power day and night, through every season, almost anywhere on earth, that has been proven to work on a large scale.
