[The Constitution] is the keystone of our nation. It is the guarantee of our liberty. That original document, with the Bill of Rights, constitutes the charter of our freedom. Through all of the years that have followed we have had some ambitious men who have sought to subvert the great principles of the Constitution, but somehow we have endured one crisis after another. We have been involved in terrible wars during this, the bloodiest of all centuries in the history of man. All of this is part of the miracle that is America, the struggle, the travail, the bitterness, the jealousies, the cynicism, and the criticism. But beyond and above it all is the wonder of a nation that for more than two centuries has remained free and independent and strong, the envy of the world, the hope of the world, the protection of free men everywhere, the manifestation of the power of the Almighty.
