The process of building the bomb is a lot less complicated than you think. As I said, the enrichment process is the difficult part. After that its a matter of high school physics to get a detonation. The seperation of U-235 from U-238 is... non-trivial, but doable. It takes about 500 lbs of natural metallic uranium to yield enough 235 for one fission core.
Hell, I'd do it for the right price, after all, its not like Im benefitting from the stability of western society. Born poor, living poor, probably die poor. What's my motivation to be a good citizen again?
