These are JFK’s last words, written for the end of a speech that he planned to give at an Austin, Texas banquet on the evening of November 22, 1963 :
“Neither the fanatics nor the faint-hearted are needed. And our duty as a Party is not to our party alone, but to the nation, and, indeed, to all mankind. Our duty is not merely the preservation of political power but the preservation of peace and freedom.
So let us not be petty when our cause is so great. Let us not quarrel amongst ourselves when our Nation’s future is at stake.”
