>olen secret nuclear program that JFK tried to shut down right before he was shot?
Oh yes, plenty of material.
The stolen plutonium from the Apollo Plant in Pennsylvania by a Mossad operative (Shapiro, Rafi Eitan).
The NUMEC affair
plenty of released CIA documents about the whole thing. OH and did you know that the CIA covered it up for many year?
Even thru the Carter Administration - many President's before him asked for a straight answer and never got one.

The Israeli plant is called Dimona - plenty of material in the JFK files as well.
Other accounts of the discovery of HEU near Dimonasaid that the isotopic “signature” of the environmental samples showed that some of the HEU was enriched at the AEC plant in Portsmouth.[8] Several of these accounts attribute the source of the Portsmouth signature information to retired Air Force General Alfred Starbird of the Energy Research and Development Administration, a predecessor of the Department of Energy, who was briefed by CIA’s Theodore Shackley in the summer of 1977 (see Document 26).
(THIS is the reference to "THE SUM OF ALL FEARS")
Our Hightly Enriched Uranium which they can signature match (like the movie) was found at Ground Zero.
