In case you weren't joking: I wouldn't worry to much about the terrorist's secret nuclear program, if i were me. Fast computers are used to help design "better" nuclear weapons,that is, to tweak the output so that a greater proportion of the weapons yield is expressed as EMP, or gamma radiation, or explosive force, and so on. They aren't needed at all to build a basic device. And military encryption, you shouldn't be to concerned about either. you'll note that $300K gets you 85th on the list... but the NSA are't really considered to be big publicity hounds. If I were you, I'd worry about more substantial dangers to our american way of life. Like people who reflexively argue for government control over anything that they don't understand.
