Oh hell. Fifty years? Five hundred years? It's not a meaningful question.
All of Libya's purchased nuke accessories were all still sitting in crates, unopened, with their original North Korean and Pakistani packing materials, including the stuff that was stored upside down, the fragile stuff that had been repeatedly dropped, the stuff that had been damaged by sand, mold, improper storage, leaks, that had been purloined and sold for scrap, misplaced, lost, abandoned. In short, it was a giant pile of second rate junk that maybe, some country that really had a sophisticated infrastructure and the pretensions to an industrial base might have turned into the foundations of a nuclear weapon in a few decades.
Was Libya that country? Let me put it this way. They needed to import their elevator repairmen.... from Italy!
