Looking back The issue of Israel's possible reprocessing of spent fuel for plutonium continued to bedev­ il U.S. intelligence throughout the 1960s. No one was sure whether Israel already had a se­ cret reprocessing site or had yet to build one. In retrospect, however, the 1963 exchange of letters between Kennedy and Ben-Gurion and Eshkol was the climax of the battle the U.S. leader waged against the Israeli nuclear project throughout his presidency. For Ken­ nedy, the stakes were higher than the status of Israel's nuclear program. At issue was the fate of his effort to halt global nuclear pro­ liferation. Israel was the first such case the Kennedy administration had to face in which it had some political leverage. If Kennedy failed to halt Israel's nuclear aspirations, how could he stop others, such as India? The reactor at Nahal Sorek. After two visiting Atomic Energy Commission scientists had inspected this small, U.S.-supplied facility, they were unexpectedly offered a sightseeing tour- that ended with a stop at Dimona. A/o11 R011
