BY THE PRESIDENT OF THE UNITED STATES OF AMERICA
A PROCLAMATION
WHEREAS the peace of the world and the security of the United States and of all American States
are endangered by reason of the establishment by the Sino-Soviet powers of an offensive military
capability in Cuba, including bases for ballistic missiles with a potential range covering most of
North and South America;
WHEREAS by a Joint Resolution passed by the Congress of the United States and approved on
October 3, 1962, it was declared that the United is determined to prevent by whatever means may be
necessary, including by the use of arms the Marxist-Leninist regime in Cuba from extending, by force
or the threat of force, its aggressive or subversive activities to any part of the hemisphere, and
to prevent in Cuba the creation or use of an externally supported military capability endangering
the security of the United States; and
WHEREAS the Organ of Consultation of the American Republics meeting in Washington on
October 23, 1962, recommended that the Member States, in accordance with
Article 6 and 8 of the Inter-American Treaty of Reciprocal Assistance, take all measures,
individually and collectively, including the use of armed force, which they may deem necessary to
ensure that the Government of Cuba cannot continue to receive from the Sino-Soviet powers military
material and related supplies which may threaten the peace and security of the Continent and to
prevent the missiles in Cuba with offensive capability from ever becoming an active threat to the
peace and security of the Continent;
NOW, THEREFORE, I, JOHN F. KENNEDY, President of the United States of
America, acting under and by virtue of the authority conferred upon me by the
Constitution and statues of the United States, in accordance with the aforementioned resolutions of the
United States Congress and of the Organ of Consultation of the American Republics, and to defend the
security of the United States, do hereby proclaim that the forces under my command are ordered, beginning at
2:00 P.M. Greenwich time October 24, 1962, to interdict, subject to the instructions herein contained,
the delivery of offensive weapons and associated material to Cuba.
For the purpose of the Proclamation, the following are declared to be

and guided missiles; warheads for any of the above weapons; mechanical or electronic equipment to
support or operate the above items; and any other classes of material hereafter designated by the
Secretary of Defense for the purpose of effectuating this Proclamation.
To enforce their order, the Secretary of Defense shall take appropriate
measures to prevent the delivery of prohibited material to Cuba, employing the land, sea and air
forces of the United States in cooperation with any forces that may be made available by the American

All vessels or craft taken into custody shall be sent into a port of the United Sates for appropriate

In carrying out this order, force shall not be used except in case of

or in case of self-defense. In any case, force shall be used only to the extent necessary.
IN WITNESS WHEREOF, I have hereunto set my hand and caused the seal of the
United States of America to be affixed.
