Here is what the Bulletin of the Atomic Scientists has to say about the NUMEC affair: "Time for real transparency. It's fair to ask, in view of the other losses in the US nuclear weapons complex, why the CIA and others singled out NUMEC for grave suspicion as the source for Israeli bomb-grade uranium. In brief, the reasons are these: NUMEC's unexplained losses were a significantly larger proportion of its throughput of highly enriched uranium than was the case for other firms that dealt with nuclear materials. Sloppy accounting and lax security made the plant easy to rob without detection. NUMEC had commercial relationships with Israel’s defense and nuclear establishments and regularly made sizeable nuclear shipments to Israel, which at that time were not checked by the AEC. NUMEC’s owners and executives had extremely close ties to Israel, including to high Israeli intelligence and nuclear officials. Israel had strong motives to obtain the highly enriched uranium before it was producing enough plutonium for weapons. High-level Israeli intelligence operatives visited the NUMEC plant. Israeli intelligence organizations were used to running logistically complicated, risky operations to support nuclear weapons development, and it would have been very much out of character for them to pass up an opportunity like this. On top of all this, records show the CIA believed its 1968 environmental sample taken in Israel evidenced an enrichment level unique to Portsmouth." http://thebulletin.org/did-israel-steal-bomb-grade-uranium-united-states7056 http://thebulletin.org/did-israel-steal-bomb-grade-uranium-u...
