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 Berliner"), which Kennedy himself had begun to try out in preparation for the trip.[241] Kennedy remarked to Ted Sorensen afterwards: "We'll never have another day like this one, as long as we live."[242]

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."[243]
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.
