Memorandum by Mr. Carlton Savage, Member of the Policy Planning Staff, to Mr. Paul H. Nitze, Director of the Policy Planning Staff

top secret

The attached paper concerning the conditions which might call for a U.S. declaration of war has a direct bearing on the questions of mobilization and execution of war plans. It seems to me that the subject is appropriate for consideration in connection with them.

The paper embodies suggestions made by George Kennan and he concurs in the conclusions and recommendations. The legal aspects of the paper were gone over by Mr. Yingling, a senior officer of “L”, and it embodies some suggestions made by him.

Possible Generalization of Hostilities

With the possibility of the enlargement of hostilities in Korea and of the inauguration of hostilities elsewhere, there has been raised the question under what conditions a U.S. declaration of war would be called for. It is appropriate, therefore, to reexamine the implications of such an act.

In the two world wars of this century we have not “declared war”, but the Congress by joint resolution has recognized that a state of war has been thrust upon us. Typical of these resolutions is the following of December 8, 1941:

“Whereas the Imperial Government of Japan has committed unprovoked acts of war against the Government and the people of the United States of America: Therefore be it

Resolved by the Senate and House of Representatives of the United States of America in Congress assembled, That the state of war between the United States and the Imperial Government of Japan which has thus been thrust upon the United States is hereby formally declared; and the President is hereby authorized and directed to employ the entire naval and military forces of the United States and the resources of the government to carry on war against the Imperial Government [Page 359] of Japan; and, to bring the conflict to a successful termination, all of the resources of the country are hereby pledged by the Congress of the United States.”

Two points should be noted in this resolution: (1) the initiative does not come from the United States;

(2) “all of the resources” of the United States are pledged to the successful termination of the conflict.

The state of war established by resolution is customarily terminated by peace treaty. There has been no peace treaty between the United States and Japan nor between the United States and Germany; a technical state of war exists with those countries, although the President has proclaimed the cessation of hostilities (see L memo attached.)2

The consequences of the declaration of a state of war are clear from the terms of the resolution. With its approval by the President, we start down a road from which there is no turning back. We pledge all our resources, human and material, to winning the war. We will to fight until one of the parties capitulates or there is a negotiated peace.

What would be the outcome if the United States entered into a state of war against the Soviet Union? While it is assumed that the Soviet Union could not now win a war against the United States, it is improbable that the United States could now fight a war against the Soviet Union to the point of the latter’s unconditional surrender. This is recognized in NSC 20/4,3 which states that we should endeavor in such a war to accomplish our objectives “without a predetermined requirement for unconditional surrender”. It should be a war of limited objectives, and one which might be terminated without a peace treaty.

With this in mind, and realizing that since it is not Communist practice to issue a declaration of war the initiative would have to come from us, we should use the device of recognition of a state of war only as a final resort. We should not thus generalize hostilities and restrict our freedom of action unless the Soviet Union affronts us in such a manner that no other course is possible, or unless we decide that a generalization of hostilities is in our National interest.

We should leave ourselves free to take limited military action against Soviet forces without a declaration, if this seems advisable. We have considerable maneuverability for this purpose.

The President’s Proclamation of unlimited national emergency of May 27, 1941 is still in effect. In it the President (1) proclaims that [Page 360] the emergency requires U.S. military, naval, air and civilian defenses be put on the basis of readiness to repel acts or threats of aggression directed toward the Western Hemisphere; (2) calls upon citizens engaged in production for defense to give precedence to the needs of the nation; (3) calls for cooperation to assure internal security; and (4) calls upon all “loyal citizens to place the nation’s needs first in mind and in action to the end that we may mobilize and have ready for instant defensive use all of the physical powers, all of the moral strength and all of the material resources of this nation.” There are also some hundred war-time statutes still in effect.

The United Nations Charter does not require the member nations to enter into a state of war in case of aggression, but merely to take such military action as is necessary to “maintain or to restore international peace and security,” as is now being done in the case of the conflict in Korea. The Charter leaves each nation free to determine how it will carry out its obligations under the Charter. Consequently, it is a domestic matter whether we carry them out with or without a declaration of war.

The Atlantic Treaty is in effect a defensive military alliance, but it does not require the parties to enter into a state of war as did the Anglo-Japanese Alliance of 1902 and the United Nations Declaration of 1941. It merely provides that in case of an attack on one of the parties, the others will assist that party with appropriate action including the use of armed force. If Russia or a Russian satellite attacks one of the nations party to the Atlantic Treaty, our coming to its assistance would not necessarily call for a U.S. declaration of war. However, if there was a resultant generalization of hostilities, a declaration almost certainly would be required.

conclusions

1.
Extensive hostilities can be carried on by the United States without a formal declaration of a state of war.
2.
Such a declaration should be made only when required by overwhelming National interest.
3.
The National interest might require that we carry on limited hostilities against the military forces of the Soviet Union without a declaration.

recommendation

The Secretary should discuss this matter with the President.
