Clinton gave them the technology for nuclear power, yet never followed up to make sure they were not enriching uranium. They trusted the NK's at face value and failed us.
No he didn't. Their nuclear reactor/reprocessing plants were home grown/Soviet derived via China. The actual reactor design, optimized to make plutonium, was copied from the British (its a British Magnox design) via Soviet versions.
Clinton promised him a nuclear power plant (a US PWR) as an incentive, not very useful for nuclear weapons production, but the US never delivered one as the NK's didn't keep their side of the bargain wrt missiles.
