117. Memorandum From the President's Assistant for National Security Affairs (Kissinger) to President Nixon 1


  • Our Present Course on Vietnam

I have become deeply concerned about our present course on Vietnam. This memorandum is to inform you of the reasons for my concern. It does not discuss alternative courses of action, but is provided for your background consideration. You know my recommendations.

While time acts against both us and our enemy, it runs more quickly against our strategy than against theirs. This pessimistic view [Page 371]is based on my view of Hanoi's strategy and the probable success of the various elements of our own.

I. U.S. Strategy

In effect, we are attempting to solve the problem of Vietnam on three highly interrelated fronts: (1) within the U.S., (2) in Vietnam, and (3) through diplomacy. To achieve our basic goals through diplomacy, we must be reasonably successful on both of the other two fronts.

a. U.S.

The pressure of public opinion on you to resolve the war quickly will increase—and I believe increase greatly—during the coming months. While polls may show that large numbers of Americans now are satisfied with the Administration's handling of the war, the elements of an evaporation of this support are clearly present. The plans for student demonstrations in October are well known, and while many Americans will oppose the students' activities, they will also be reminded of their own opposition to the continuation of the war.2 As mentioned below, I do not believe that “Vietnamization” can significantly reduce the pressures for an end to the war, and may, in fact, increase them after a certain point. Particularly significant is the clear opposition of many “moderate” leaders of opinion, particularly in the press and in the East (e.g., Life Magazine). The result of the recrudescence of intense public concern must be to polarize public opinion. You will then be somewhat in the same position as was President Johnson, although the substance of your position will be different. You will be caught between the Hawks and the Doves.

The effect of these public pressures on the U.S. Government will be to accentuate the internal divisiveness that has already become apparent to the public and Hanoi. Statements by government officials which attempt to assuage the Hawks or Doves will serve to confuse Hanoi but also to confirm it in its course of waiting us out.

b. Vietnam

Three elements on the Vietnam front must be considered—(1) our efforts to “win the war” through military operations and pacification, (2) “Vietnamization,” and (3) the political position of the GVN.

I do not believe that with our current plans we can win the war within two years, although our success or failure in hurting the enemy remains very important.3
“Vietnamization” must be considered both with regard to its prospects for allowing us to turn the war over to the Vietnamese, and with regard to its effect on Hanoi and U.S. public opinion. I am not optimistic about the ability of the South Vietnamese armed forces to assume a larger part of the burden than current MACV plans allow. These plans, however, call for a thirty-month period in which to turn the burden of the war over to the GVN. I do not believe we have this much time.

In addition, “Vietnamization” will run into increasingly serious problems as we proceed down its path.

  • —Withdrawal of U.S. troops will become like salted peanuts to the American public: The more U.S. troops come home, the more will be demanded. This could eventually result, in effect, in demands for unilateral withdrawal—perhaps within a year.
  • —The more troops are withdrawn, the more Hanoi will be encouraged—they are the last people we will be able to fool about the ability of the South Vietnamese to take over from us. They have the option of attacking GVN forces to embarrass us throughout the process or of waiting until we have largely withdrawn before doing so (probably after a period of higher infiltration).
  • —Each U.S. soldier that is withdrawn will be relatively more important to the effort in the south, as he will represent a higher percentage of U.S. forces than did his predecessor. (We need not, of course, continue to withdraw combat troops but can emphasize support troops in the next increments withdrawn. Sooner or later, however, we must be getting at the guts of our operations there.)
  • —It will become harder and harder to maintain the morale of those who remain, not to speak of their mothers.
  • —”Vietnamization” may not lead to reduction in U.S. casualties until its final stages, as our casualty rate may be unrelated to the total number of American troops in South Vietnam. To kill about 150 U.S. soldiers a week, the enemy needs to attack only a small portion of our forces.
  • —“Vietnamization” depends on broadening the GVN, and Thieu's new government is not significantly broader than the old (see below). The best way to broaden the GVN would be to create the impression that the Saigon government is winning or at least permanent. The more uncertainty there is about the outcome of the war, the less the prospect for “Vietnamization.”

(3) We face a dilemma with the GVN: The present GVN cannot go much farther towards a political settlement without seriously endangering its own existence; but at the same time, it has not gone far enough to make such a settlement likely.

[Page 373]

Thieu's failure to “broaden” his government is disturbing, but not because he failed to include a greater variety of Saigon's Tea House politicians. It is disturbing because these politicians clearly do not believe that Thieu and his government represent much hope for future power, and because the new government does not offer much of a bridge to neutralist figures who could play a role in a future settlement.4 This is not to mention his general failure to build up political strength in non-Catholic villages. In addition, as U.S. troops are withdrawn, Thieu becomes more dependent on the political support of the South Vietnamese military.

c. Diplomatic Front

There is not therefore enough of a prospect of progress in Vietnam to persuade Hanoi to make real concessions in Paris. Their intransigence is also based on their estimate of growing U.S. domestic opposition to our Vietnam policies. It looks as though they are prepared to try to wait us out.

II. Hanoi's Strategy

There is no doubt that the enemy has been hurt by allied military actions in the South, and is not capable of maintaining the initiative on a sustained basis there. Statistics on enemy-initiated activities, as well as some of Giap's recent statements, indicate a conscious decision by Hanoi to settle down to a strategy of “protracted warfare.” This apparently consists of small unit actions with “high point” flurries of activity, and emphasis on inflicting U.S. casualties (particularly through rocket and mortar attacks). This pattern of actions seems clearly5 to indicate a low-cost strategy aimed at producing a psychological, rather than military, defeat for the U.S.

This view of their strategy is supported by our estimates of enemy infiltration. They could infiltrate more men, according to intelligence estimates, despite growing domestic difficulties. The only logical reason for their not having done so is that more men were not needed in the pipeline—at least for a few months—to support a lower-cost strategy of protracted warfare. It seems most unlikely that they are attempting to “signal” to us a desire for a de facto mutual withdrawal, although this cannot be discounted.6 There is no diplomatic sign of this—except in Xuan Thuy's linkage of points two and three of the PRG program— and I do not believe they trust us enough to “withdraw” a larger percentage of their men than we have of ours, as they would be doing.

[Page 374]

Hanoi's adoption of a strategy designed to wait us out fits both with its doctrine of how to fight a revolutionary war and with its expectations about increasingly significant problems for the U.S.7

III. Conclusion

In brief, I do not believe we can make enough evident progress in Vietnam to hold the line within the U.S. (and the U.S. Government), and Hanoi has adopted a strategy which it should be able to maintain for some time—barring some break like Sino-Soviet hostilities. Hence my growing concern.
