President's speech:
President John F. Kennedy
Delivered in person before a joint session of Congress
May 25, 1961
Mr. Speaker, Mr. Vice President, my co-partners in Government, gentlemen and ladies:
The Constitution imposes upon me the obligation to "from time to time give to the Congress information of the State of the Union." While this has traditionally been interpreted as an annual affair, this tradition has been broken in extraordinary times.
These are extraordinary times. And we face an extraordinary challenge. Our strength as well as our convictions have imposed upon this nation the role of leader in freedom's cause.
No role in history could be more difficult or more important. We stand for freedom.
That is our conviction for ourselves--that is our only commitment to others. No friend, no neutral and no adversary should think otherwise. We are not against any man--or any nation--or any system--except as it is hostile to freedom. Nor am I here to present a new military doctrine, bearing any one name or aimed at any one area. I am here to promote the freedom doctrine.
