The speech is considered one of Kennedy’s best, both a notable moment of the Cold War and a high point of the New Frontier. It was a great morale boost for West Berliners, who lived in an enclave deep inside East Germany and feared a possible East German occupation. Speaking from a platform erected on the steps of Rathaus Schöneberg for an audience of 450,000, Kennedy said: Two thousand years ago, the proudest boast was civis romanus sum [“I am a Roman citizen”]. Today, in the world of freedom, the proudest boast is “Ich bin ein Berliner!“… All free men, wherever they may live, are citizens of Berlin, and therefore, as a free man, I take pride in the words “Ich bin ein Berliner!”.
Kennedy used the phrase twice in his speech, including at the end, pronouncing the sentence with his Boston accent and reading from his note “ish bin ein Bearleener”, which he had written out using English spelling habits to indicate an approximation of the German pronunciation. Another phrase in the speech was also spoken in German, “Lass’ sie nach Berlin kommen” (“Let them come to Berlin”), addressed at those who claimed “we can work with the Communists”.
While the immediate response from the West German population was positive, the Soviet authorities were less pleased with the combative Lass sie nach Berlin kommen. Only two weeks before, Kennedy had spoken in a more conciliatory tone, speaking of “improving relations with the Soviet Union”: in response to Kennedy’s Berlin speech, Nikita Khrushchev, days later, remarked that “one would think that the speeches were made by two different Presidents”.
Kennedy held the speech on 26 June 1963, less then 3 months later he was killed.
