I too could build both fission and fusion weapons. I've know how ever since I was in high school. Or go read the book "The Circle of Binding Energy."

'Tain't hard to build a gun-type fission weapon. And you can even trigger it with a suicide-type fanatic (I can find plenty around here who would do it because killing "Liberals" will insure their entry into Heaven, the provision of 144 wild virgin bikini dancers and an eternity of light beer).

A human-triggered fission weapon wouldn't have the yield of a well-engineered one or an implosion weapon, probably only about .8 KT and a LOT of fallout -- mind you, that's the equivalent of about 800 tons of TNT and a "dead zone" of radioactivity.

Don't go bad-mouthing BB or Don Firth -- they're dead right about building nukes.
