No. 499
The Acting Assistant Secretary of State for Far Eastern Affairs (Allison) to the Assistant to the Secretary of Defense for International Security Affairs (Nash)

top secret

Dear Mr. Nash: We have been discussing an Interim Policy Guidance and an Interim Directive to the Commander in Chief, Far East setting forth preliminary United States policies with respect to Japan in the post-Treaty period. In the course of these discussions we have agreed that it will be desirable to push ahead with the preparation of a National Security Council paper on Japan.

I have asked the Office of Northeast Asian Affairs to prepare a draft of such an NSC paper which can then be started through the normal NSC processes. However in commencing their consideration of such a paper, they have discovered the desirability of a military estimate of certain factors regarding the security of Japan, in order to make possible a more intelligent approach to some of the major problems of policy. Enclosed are four copies of a list of questions, the answers to which would lay a firm groundwork for the NSC paper.

I realize that some of these questions have already been the subject of considerable study, and that some of the answers have been communicated to the Department in Mr. Lovett’s letter of January 10.1 The questions are included at this time, however, partly for the sake of completeness and partly to be sure that we have the benefit of your latest thinking. Other questions listed in the enclosure it may not be possible to answer, but to the extent that even tentative answers are possible we will all have a better basis for considering what our policies toward Japan should be.

In case you believe discussion of some of these points between Defense and State representatives will be fruitful, Mr. McClurkin of the Office of Northeast Asian Affairs will be glad to consult with anyone whom you may designate.

Sincerely yours,

John M. Allison

Problems To Be Clarified Prior to Preparation of NSC Paper

I. The effective potential over the next few years of United States and Japanese military forces in Japan in resisting attack.

A.
To what extent is it possible and desirable from a military point of view to defend Japan against attack?
1.
How much of Japan can be held against attack?
2.
To what extent can Japanese production facilities remain in operation in the event of hostilities in the Japan area?
3.
Is it expected that adequate shipping will be available to supply United States and Japanese military forces in Japan and Japanese industrial and civilian requirements? Can this shipping be adequately protected against attack?
B.
Consistent with the answers to the foregoing, what is the estimated strength of United States air, naval and ground forces required to defend Japan effectively?
1.
Consistent with Japanese resources, to what extent is it proposed to create Japanese ground forces, i.e., magnitude, character and timing, as a means of strengthening the defense of the area and of eventually releasing United States forces for duty elsewhere?
2.

Is it contemplated that approval would be given to the creation of Japanese—

a.
naval forces,
b.
tactical air force,
c.
strategic bombing force,

and if so, to what extent?

C.
Consistent with the estimates made in response to B above, what will be the approximate costs of maintaining United States and Japanese forces in Japan for each of the next three years, broken down as follows:
1.
Total costs of maintaining United States forces in Japan.
a.
Costs to be borne by the United States.

(1) Approximately what portion of this will be expended in Japan?

b.
Costs to be borne by the Japanese Government.
2.
Total costs of maintaining Japanese forces.
a.
Dollar expenditures of the United States for military equipment, etc.

(1)What portion of this, if any, will be expended in Japan?

b.
Costs to be borne by the Japanese Government.

(1) To what extent would this involve expenditure of foreign exchange by Japan?

c.
What proportion of the total costs for maintaining Japanese forces would be required for—
(1)
Light military equipment,
(2)
Heavy military equipment.

II. Development and use of Japanese industrial capacity for the production of military supplies and implements of war.

A.
To what extent will scarcities and delays in United States industrial production have an effect on the ability of the United States to supply U.S. and Japanese forces in Japan?
1.
To what extent will such shortages be a limiting factor upon the desired development of Japanese forces until alternative supplies of such resources can be made available?
2.
Is there a critical year involved?
B.
Mindful of the current scarcities of certain vital materials, the present and potential capabilities of Japanese industries, the alternate uses of those industrial resources, the present and future impact on the Japanese economy, the possibility of a loss of Japan in the event of a general war, and the shipping requirements to supply necessary imports for Japanese industry during a war, what are the views of Defense with respect to the development and use of industrial capacity in Japan for the production of military supplies and equipment for—
1.
United States forces in Japan.
2.
United States forces stationed elsewhere.
3.
Japanese security forces, and
4.
Other friendly forces in Asia.
C.
Specifically, what are the views of Defense with reference to the types of military supplies and equipment which Japan should produce?

1. Should a distinction be made between encouragement of Japanese heavy and light armament industries?

  1. Reference uncertain. Possibly pertains to a letter of Jan. 10 signed on behalf of Lovett by Col. K.R. Kreps, USAF, Deputy Director of the Executive Office of the Secretary of Defense, enclosing a JCS memorandum of Dec. 12, 1951. For text of the latter memorandum, see Foreign Relations, 1951, vol. vi, Part 1, p. 1432.
