My dad is a nuke engineer (studied under Rickover) who hires bomb designers -- he maintains that the physics behind building a bomb is simple and easy, and far from classified. What distinguishes the really scary weapons from home-brew isn't the science behind it, but all the engineering tweaks that optimize the results. Given his background and Q clearance in DOE, even if he wasn't my dad, I'd be inclined to believe him....
