Don't forget JFK: we're all the better for US leadership "WE will never have another day like this one," said John F. Kennedy as he slumped, exhausted, into his chair on Air Force One and it took off for Dublin. Sadly, he was right. His visit to Berlin in June 1963 was his last great hurrah. He was assassinated a few months later. Next week is the 50th anniversary of one of the most famous and significant speeches of the post-war era. Standing on the steps of City Hall in West Berlin, Kennedy issued a challenge to those who doubted the value and durability of freedom: "Lass' sie nach Berlin kommen." Let them come to Berlin. And he finished his short address with the celebrated words with which he will always be associated: "Ich bin ein Berliner."
