McCone Memo to Top Officials on Effectiveness of Air War
Memorandum from John A. McCone, Director of Central Intelligence, to Secretary Rusk, Secretary McNamara, McGeorge Bundy and Ambassador Taylor, April 2, 1965, as provided in the body of the Pentagon’s study. Paragraphs in italics are the study’s paraphrase or explanation.
McCone did not inherently disagree with the change in the U.S. ground-force role, but felt that it was inconsistent with the decision to continue the air strike program at the feeble level at which it was then being conducted. McCone developed his argument as follows:
I have been giving thought to the paper that we discussed in yesterday’s meeting, which unfortunately I had little time to study, and also to the decision made to change the mission of our ground forces in South Vietnam from one of advice and static defense to one of active combat operations against the Viet Cong guerrillas.
I feel that the latter decision is correct only if our air strikes against the North are sufficiently heavy and damaging really to hurt the North Vietnamese. The paper we examined yesterday does not anticipate the type of air operation against the North necessary to force the NVN to reappraise their policy. On the contrary, it states, “We should continue roughly the present slowly ascending tempo of ROLLING THUNDER operations——,” and later, in outlining the types of targets, states, “The target systems should continue to avoid the effective GCI range of MIG’s,” and these conditions indicate restraints which will not be persuasive to the NVM and would probably be read as evidence of a U.S. desire to temporize.
I have reported that the strikes to date have not caused a change in the North Vietnamese policy of directing Viet Cong insurgency, infiltrating cadres and supplying material. If anything, the strikes to date have hardened their attitude.
I have now had a chance to examine the 12-week program referred to by General Wheeler and it is my personal opinion that this program is not sufficiently severe and [words illegible] the North Vietnamese to [words illegible] policy.
On the other hand, we must look with care to our position under a program of slowly ascending tempo of air strikes. With the passage of each day and each week, we can expect increasing pressure to stop the bombing. This will come from various elements of the American public, from the press, the United Nations and world opinion. Therefore time will run against us in this operation and I think the North Vietnamese are counting on this.
Therefore I think what we are doing is starting on a track which involves ground force operations, which, in all probability, will have limited effectiveness against guerrillas, although admittedly will restrain some VC advances. However, we can expect requirements for an ever-increasing commitment of U.S. personnel without materially improving the chances of victory. I support and agree with this decision but I must point out that in my judgment, forcing submission of the VC can only be brought about by a decision in Hanoi. Since the contemplated actions against the North are modest in scale, they will not impose unacceptable damage on it, nor will they threaten the DRV’s vital interests. Hence, they will not present them with a situation with which they cannot live, though such actions will cause the DRV pain and inconvenience.
I believe our proposed track offers great danger of simply encouraging Chinese Communists and Soviet support of the DRV and VC cause, if for no other reason than the risk for both will be minimum. I envision that the reaction of the NVN and Chinese Communists will be to deliberately, carefully, and probably gradually, build up the Viet Cong capabilities by covert infiltration on North Vietnamese and, possibly, Chinese cadres and thus bring an ever-increasing pressure on our forces. In effect, we will find ourselves mired down in combat in the jungle in a military effort that we cannot win, and from which we will have extreme difficulty in extracting ourselves.
Therefore it is my judgment that if we are to change the mission of the ground forces, we must also change the ground rules of the strikes against North Vietnam. We must hit them harder, more frequently, and inflict greater damage. Instead of avoiding the MIG’s, we must go in and take them out. A bridge here and there will not do the job. We must strike their airfields, their petroleum resources, power stations and their military compounds. This, in my opinion, must be done promptly and with minimum restraint.
If we are unwilling to take it this kind of a decision now, we must not take the actions concerning the mission of our ground forces for the reasons I have mentioned [words illegible].

April, ’65, Order Increasing Ground Force and Shifting Mission
National Security Action Memorandum 328, April 6, 1965, signed by McGeorge Bundy and addressed to the Secretary of State, the Secretary of Defense and the Director of Central Intelligence.
On Thursday, April 1, The President made the following decisions with respect to Vietnam:
1. Subject to modifications in light of experience, to coordination and direction both in Saigon and in Washington, the President approved the 41-point program of non-military actions submitted by Ambassador Taylor in a memorandum dated March 31, 1965.
2. The President gave general approval to the recommendations submitted by Mr. Rowan in his report dated March 16, with the exception that the President withheld approval of any request for supplemental funds at this time—it is his decision that this program is to be energetically supported by all agencies and departments and by the reprogramming of available funds as necessary within USIA.
3. The President approved the urgent exploration of the 12 suggestions for covert and other actions submitted by the Director of Central Intelligence under date of March 31.
4. The President repeated his earlier approval of the 21-point program of military actions submitted by General Harold K. Johnson under date of March 14 and re-emphasized his desire that aircraft and helicopter reinforcements under this program be accelerated.
5. The President approved an 18-20,000 man increase in U.S. military support forces to fill out existing units and supply needed logistic personnel.
6. The President approved the deployment of two additional Marine Battalions and one Marine Air Squadron and associated headquarters and support elements.
7. The President approved a change of mission for all Marine Battalions deployed to Vietnam to permit their more active use under conditions to be established and approved by the Secretary of Defense in consultation with the Secretary of State.
8. The President approved the urgent exploration, with the Korean, Australian, and New Zealand Governments, of the possibility of rapid deployment of significant combat elements from their armed forces in parallel with the additional Marine deployment approved in paragraph 6.
9. Subject to continuing review, the President approved the following general framework of continuing action against North Vietnam and Laos:
We should continue roughly the present slowly ascending tempo of ROLLING THUNDER operations being prepared to add strikes in response to a higher rate of VC operations, or conceivably to slow the pace in the unlikely event VC slacked off sharply for what appeared to be more than a temporary operational lull.
The target systems should continue to avoid the effective GGI range of MIGs. We should continue to vary the types of targets, stepping up attacks on lines of communication in the near future, and possibly moving in a few weeks to attacks on the rail lines north and northeast of Hanoi.
Leaflet operations should be expanded to obtain maximum practicable psychological effect on North Vietnamese population.
Blockade or aerial mining of North Vietnamese ports need further study and should be considered for future operations. It would have major political complications, especially in relation to the Soviets and other third countries, but also offers many advantages.
Air operation in Laos, particularly route blocking operations in the Panhandle area, should be stepped up to the maximum remunerative rate.
10. Ambassador Taylor will promptly seek the reactions of the South Vietnamese Government to appr
opriate sections of this program and their approval as necessary, and in the event of disapproval or difficulty at that end, these decisions will be appropriately reconsidered. In any event, no action into Vietnam under paragraphs 6 and 7 above should take place without GVN approval or further Presidential authorization.
11. The President desires that with respect to the actions in paragraphs 5 through 7, premature publicity be avoided by all possible precautions. The actions themselves should be taken as rapidly as practicable, but in ways that should minimize any appearance of sudden changes in policy, and official statements on these troop movements will be made only with the direct approval of the Secretary of Defense, in consultation with the Secretary of State. The President’s desire is that these movements and changes should be understood as being gradual and wholly consistent with existing policy.

Taylor Cable to Washington on Step-Up in Ground Forces
Cablegram April 17, 1965, from Ambassador Maxwell D. Taylor in Saigon to Secretary of State Dean Rusk, with a copy to the White House for the attention of McGeorge Bundy.
This message undertakes to summarize instructions which I have received over the last ten days with regard to the introduction of third-country combat forces and to discuss the preferred way of presenting the subject to the GVN.
As the result of the meeting of the President and his advisors on April 1 and the NSC meeting on the following day, I left Washington and returned to Saigon with the understanding that the reinforcement of the Marines already ashore by two additional BLT’s and a F-4 squadron and the progressive introduction of IIAWPNPPP support forces were approved but that decision on the several proposals for bringing in more U.S. combat forces and their possible modes of employment was withheld in an offensive counterinsurgency role. State was to explore with the Korean, Australian and New Zealand govts the possibility of rapid deployment of significant combat elements in parallel with the Marine reinforcement.
Since arriving home, I have received the following instructions and have taken the indicated actions with respect to third-country combat forces.
April 6 and 8. Received GVN concurrence to introduction of the Marine reinforcements and to an expanded mission for all Marines in Danang-Phu Bai area.
April 8. Received Deptel 2229 directing approach to GVN, suggesting request to Australian govt for an infantry battalion for use in SVN. While awaiting a propitious moment to raise the matter, I received Deptel 2237 directing approach be delayed until further orders. Nothing further has been received since.
April 14. I learned by JCS 009012 to Cincpac of apparent decision to deploy 173rd airborne brigade immediately to Bien Hoa-Vung Tau. By Embtel 3373, delay in this deployment was urgently recommended but no reply has been received. However, Para 2 of Doc 152339 apparently makes reference to this project in terms which suggest that is something less than as an approved immediate action. In view of the uncertainty of its status, I have not broached the matter with Quat.
April 15. Received Deptel 2314 directing that embassy Saigon discuss with GVN introduction of Rok regimental combat team and suggest GVN request such a force Asap. Because of Quat’s absence from Saigon, I have not been able to raise matter. As matter of fact, it should not be raised until we have a clear concept of employment.
April 16. I have just seen state-defense message Dod 152339 cited above which indicates a favorable attitude toward several possible uses of U.S. combat forces beyond the NSC decisions of April 2. I am told to discuss these and certain other non-military matters urgently with Quat. The substance of this cable will be addressed in a separate message. I can not raise these matters with Quat without further guidance.
Faced with this rapidly changing picture of Washington desires and intentions with regard to the introduction of third-country (as well as U.S.) combat forces, I badly need a clarification of our purposes and objectives. Before I can present our case to GVN, I have to know what that case is and why. It is not going to be easy to get ready concurrence for the large-scale introduction of foreign troops unless the need is clear and explicit.
Let me suggest the kind of instruction to the AMB which it would be most helpful to receive for use in presenting to GVN what I take to be a new policy of third-country participation in ground combat.
“The USG has completed a thorough review of the situation in SVN both in its national and international aspects and has reached certain important conclusions. It feels that in recent weeks there has been a somewhat favorable change in the overall situation as the result of the air attacks on DRV, the relatively small but numerous successes in the field against the VC and the encouraging progress of the Quat govt. However, it is becoming increasingly clear that, in all probability, the primary objective of the GVN and the USG of changing the will of the DRV to support the VC insurgency can not be attained in an acceptable time-frame by the methods presently employed. The air campaign in the North must be supplemented by signal successes against the VC on the South before we can hope to create that frame of mind in Hanoi which will lead to the decisions we seek.
“The JCS have reviewed the military resources which will be available in SVN by the end of 1965 and have concluded that even with an attainment of the highest feasible mobilization goals, ARVN will have insufficient forces to carry out the kind of successful campaign against the VC which is considered essential for the purposes discussed above. If the ground war is not to drag into 1966 and even beyond, they consider it necessary to reinforce GVN ground forces with about 23 battalion equivalents in addition to the forces now being recruited in SVN. Since these reinforcements can not be raised by the GVN, they must inevitably come from third-country sources.
“The USG accepts the validity of this reasoning of the JCS and offers its assistance to the GVN to raise these additional forces for the purpose of bringing the VC insurgency to an end in the shortest possible time. We are prepared to bring in additional U.S. ground forces provided we can get a reasonable degree of participation from other third countries. If the GVN will make urgent representations to them, we believe it entirely possible to obtain the following contributions; Korea, one regimental combat team; Australia, one infantry battalion; New Zealand, one battery and one company of tanks; PI, one battalion. If forces of the foregoing magnitude are forthcoming, the USG is prepared to provide the remainder of the combat reinforcements as well as the necessary logistic personnel to support the third-country contingents. Also it will use its good offices as desired in assisting the GVN approach to these govts.
“You (the Ambassador) will seek the concurrence of the GVN to the foregoing program, recognizing that a large number of questions such as command relationships, concepts of employment and disposition of forces must be worked out subsequently.” Armed with an instruction such as the foregoing, I would feel adequately equipped to initiate what may be a sharp debate with the GVN. I need something like this before taking up the pending troop matters with Quat.

Johnson’s Message to Taylor on the May 10 Halt in Bombing
Message from President Johnson to Ambassador Taylor, May 10, 1965, as provided in the body of the Pentagon study.
I have learned from Bob McNamara that nearly all ROLLING THUNDER operations for this week can be completed by Wednesday noon, Washington time. This fact and the days of Buddha’s birthday seem to me to provide an excellent opportunity for a pause in air attacks which might go into next week and which I could use to good effect with world opinion.
My plan is not to announce this brief pause but simply to call it privately to the attention of Moscow and Hanoi as soon as possible and tell them that we shall be watching closely to see whether they respond in any way. My current plan is to report publicly after the pause ends on what we have done.
Could you see Quat right away on Tuesday and see if you can persuade him to concur in this plan. I would like to associate him with me in this decision if possible, but I would accept a simple concurrence or even
willingness not to oppose my decision. In general, I think it important that he and I should get together in such matters, but I have no desire to embarrass him if it is politically difficult for him to join actively in a pause over Buddha’s birthday.
[Words illegible] noted your [words illegible] but do not yet have your appreciation of the political effect in Saigon of acting around Buddha’s birthday. From my point of view it is a great advantage to use Buddha’s birthday to mask the first days of the pause here, if it is at all possible in political terms for Quat. I assume we could undertake to enlist the Archbishop and the Nuncio in calming the Catholics.
You should understand that my purpose in this plan is to begin to clear a path either toward restoration of peace or toward increased military action, depending upon the reaction of the Communists. We have amply demonstrated our determination and our commitment in the last two months, and I now wish to gain some flexibility.
I know that this is a hard assignment on short notice, but there is no one who can bring it off better.
I have kept this plan in the tightest possible circle here and wish you to inform no one but Alexis Johnson. After I have your report of Quat’s reaction I will make a final decision and it will be communicated promptly to senior officers concerned.

Rostow Memorandum on “Victory and Defeat in Guerrilla Wars”
Memorandum from Walt W. Rostow, chairman of the State Department’s Policy Planning Council, for Secretary of State Rusk, “Victory and Defeat in Guerilla Wars: The Case of South Vietnam,” May 20, 1965, as provided in the body of the Pentagon’s study.
In the press, at least, there is a certain fuzziness about the possibility of clear-cut victory in South Viet-nam; and the President’s statement that a military victory is impossible is open to misinterpretation.
