President Kennedy gave a public speech in West Berlin. He reiterated the American commitment to Germany and criticized communism, and was met with an ecstatic response from a massive audience.[227] Kennedy used the construction of the Berlin Wall as an example of the failures of communism: "Freedom has many difficulties, and democracy is not perfect. But we have never had to put a wall up to keep our people in, to prevent them from leaving us." The speech is known for its famous phrase "Ich bin ein Berliner" ("I am a citizen of Berlin"). A million people were on the street for the speech.[227] Kennedy remarked to Ted Sorensen afterwards: "We'll never have another day like this one, as long as we live."[228] See also: Tear down this wall! Israel In 1960, Kennedy stated, "Israel will endure and flourish. It is the child of hope and the home of the brave. It can neither be broken by adversity nor demoralized by success. It carries the shield of democracy and it honors the sword of freedom."[229] As president, Kennedy initiated the creation of security ties with Israel, and he is credited as the founder of the US-Israeli military alliance, which would be continued under subsequent presidents. Kennedy ended the arms embargo that the Eisenhower and Truman administrations had enforced on Israel. Describing the protection of Israel as a moral and national commitment, he was the first to introduce the concept of a "special relationship" (as he described it to Golda Meir) between the US and Israel.[230] 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.[231] 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".[232] 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".[232] In 1963 the Kennedy administration was engaged in a now declassified diplomatic standoff with the Israel.[233][234] In a May 1963 letter to Ben-Gurion, Kennedy wrote that he was skeptical and stated that American support to Israel could be in jeopardy if reliable information on the Israeli nuclear program was not forthcoming, Ben-Gurion repeated previous reassurances that Dimona was being developed for peaceful purposes. The Israeli government resisted American pressure to open its nuclear facilities to International Atomic Energy Agency (IAEA) inspections. In 1962 the US and Israeli governments had agreed to an annual inspection regime. A science attaché at the embassy in Tel Aviv concluded that parts of the Dimona facility had been shut down temporarily to mislead American scientists when they visited.[235] According to Seymour Hersh, the Israelis set up false control rooms to show the Americans. Israeli lobbyist Abe Feinberg stated: "It was part of my job to tip them off that Kennedy was insisting on [an inspection]."[235] Hersh contends that the inspections were conducted in such a way that it "guaranteed that the whole procedure would be little more than a whitewash, as the president and his senior advisors had to understand: the American inspection team would have to schedule its visits well in advance, and with the full acquiescence of Israel."[236] Marc Trachtenberg argued that "[a]lthough [he was]
