Kennedy with Israeli Foreign Minister Golda Meir, December 27, 1962
Kennedy extended the first informal security guarantees to Israel in 1962 and, beginning in 1963, was the first US president to allow the sale to Israel of advanced US weaponry (the MIM-23 Hawk) as well as to provide diplomatic support for Israeli policies, which were opposed by Arab neighbors; those policies included Israel's water project on the Jordan River.[245]
As a result of this newly created security alliance, Kennedy also encountered tensions with the Israeli government over the production of nuclear materials in Dimona, which he believed could instigate a nuclear arms-race in the Middle East. After the existence of a nuclear plant was initially denied by the Israeli government, David Ben-Gurion stated in a speech to the Israeli Knesset on December 21, 1960, that the purpose of the nuclear plant at Beersheba was for "research in problems of arid zones and desert flora and fauna".[246] When Ben-Gurion met with Kennedy in New York, he claimed that Dimona was being developed to provide nuclear power for desalinization and other peaceful purposes "for the time being".
