The Parties to this Treaty,

Reaffirming their desire to live in peace with all peoples and all governments, and desiring to strengthen the fabric of peace in the Pacific area,

Desiring to declare publicly and formally their common determination to defend themselves against external armed attack so that no potential aggressor could be under the illusion that either of them stands alone in the Pacific area,

Desiring further to strengthen their efforts for collective defense for the preservation of peace and security pending the development of a more comprehensive and effective system of regional security in the Pacific area,

Have agreed as follows:

ARTICLE I

The Parties undertake to settle any international disputes in which they may be involved by peaceful means in such a manner that international peace and security and justice are not endangered and to refrain in their international relations from the threat or use of force in any manner inconsistent with the Purposes of the United Nations, or obligations assumed by and Party toward the United Nations.

ARTICLE II

The Parties will consult together whenever, in the opinion of either of them, the political independence or security of either of the Parties is threatened by external armed attack. Separately and jointly, by self help and mutual aid, the Parties will maintain and develop appropriate means to deter armed attack and will take suitable measures in consultation and agreement to implement this Treaty and to further its purposes.

ARTICLE III

Each Party recognizes that an armed attack in the Pacific area on either of the Parties in territories now under their respective administrative control, or hereafter recognized by one of the Parties as lawfully brought under the administrative control of the other, would be dangerous to its own peace and safety and declares that it would act to meet the common danger in accordance with its constitutional processes.

ARTICLE IV

The Republic of Korea grants, and the United States of America accepts, the right to dispose United States land, air and sea forces in and about the territory of the Republic of Korea as determined by mutual agreement.

ARTICLE V

This Treaty shall be ratified by the United States of America and the Republic of Korea in accordance with their respective constitutional processes and will come into force when instruments of ratification thereof have been exchanged by them at Washington.

ARTICLE VI

This Treaty shall remain in force indefinitely. Either Party may terminate it one year after notice has been given to the other Party.

IN WITNESS WHEREOF the undersigned Plenipotentiaries have signed this Treaty.

DONE in duplicate at Washington, in the English and Korean languages, this first day of October 1953.
