NUMEC affair

There is enormous evidence, albeit not proof, that Israel smuggled enriched uranium for it's nuclear bomb program from the NUMEC plant in Apollo, Pennsylvania.  While many redacted documents have been released, the CIA is still holding on to key details 50 years later.  Is this stonewalling really to protect "Sources and Methods" or are there possibly foreign policy considerations driving it?

It's not in the above, but somewhere I read about NRC official who went straight to President Johnson with his fears about the NUMEC diversion, and Johnson simply laughed. 

Many believe now that Israel assassinated President Kennedy precisely because he started demanding an investigation of the Israeli nuclear program in April 1963.  I think there are many other sides to the assassination, but Israel probably had one part of it, certainly if Israel knew anything about the assassination plot, which it probably did, it would not have interfered to stop or reveal it.  And then there's a long list of Jewish Mafia figures believed to be involved, including Meyer Lansky and Jack Ruby.)  Johnson immediately stopped Kennedy's effort to investigate the Israeli nuclear program, and much later ignored the Israeli bombing of the USS Liberty.  It does seem like Johnson was the first fully committed Zionist US President, and they've all remained true to Zionism first ever since.  One of Johnson's closest friends was Mathilde Krim, a very committed Zionist scientist who had smuggled weapons to the Irgun back in the day.  Johnson got closer to Krim after his long time paramour Alice Moon dumped him because of the Vietnam War.
