B. PRESENT MILITARY SITUATION IN NORTH VIETNAM.
1. Physical consequences of bombing
a. The DRV has suffered some physical hardship and pain, raising the cost to it of supporting the VC.
b. Best intelligence judgment is that:
(1) Bombing may or may not—by destruction or delay—have resulted in net reduction in the flow of men or supplies to the forces in the South;
(2) Bombing has failed to reduce the limit on the capacity of the DRV to aid the VC to a point below VC needs;
(3) Future bombing of North Vietnam cannot be expected physically to limit the military support given the VC by the DRV to a point below VC needs.
2. Influence consequences of bombing
a. There is no evidence that bombings have made it more likely the DRV will decide to back out of the war.
b. Nor is there evidence that bombings have resulted in an increased DRV resolve to continue the war to an eventual victory. [Fisher’s draft had read “There is some evidence that bombings. . . .”]
C. FUTURE OF A BOMBING STRATEGY
Although bombings of North Vietnam improve GVN morale and provide a counter in eventual negotiations (should they take place) there is no evidence that they meaningfully reduce either the capacity or the will for the DRV to support the VC. The DRV knows that we cannot force them to stop by bombing and that we cannot, without an unacceptable risk of a major war with China or Russia or both, force them to stop by conquering them or “blotting them out.” Knowing that if they are not influenced we cannot stop them, the DRV will remain difficult to influence. With continuing DRV support, victory in the South may remain forever beyond our reach.
Having made the case against the bombing, the memo then spelled out the case for an anti-infiltration barrier:
II. SUBSTANCE OF THE BARRIER PROPOSAL
A. That the U.S. and GVN adopt the concept of physically cutting off DRV support to the VC by an on-the-ground barrier across the Ho Chi Minh Trail in the general vicinity of the 17th Parallel and Route 9. To the extent necessary the barrier would run from the sea across Vietnam and Laos to the Mekong, a straightline distance of about 160 miles.
B. That in Laos an “interdiction and verification zone,” perhaps 10 miles wide, be established and legitimated by such measures as leasing, international approval, compensation, etc.
C. That a major military and engineering effort be directed toward constructing a physical barrier of minefields, barbed wire, walls, ditches and military strong points flanked by a defoliated strip on each side.
D. That such bombing in Laos and North Vietnam as takes place be narrowly identified with interdiction and with the construction of the barrier by
1. Being within the 10-mile-wide interdiction zone in Laos, or
2. Being in support of the construction of the barrier, or
3. Being interdiction bombing pending the completion of the barrier.
E. That, of course, intensive interdiction continues at sea and from Cambodia.
(It might be stated that all bombings of North Vietnam will stop as soon as there is no infiltration and no opposition to the construction of the verification barrier.)

Johnson’s Remarks to Officials of U.S. and Saigon at Honolulu
Excerpts from remarks by President Johnson to senior United States and South Vietnamese after the issuance of a joint communiqué at their Honolulu conference, Feb. 9, 1966, as provided in the body of the Pentagon study. The paragraph in italics is the study’s explanation.
(The Vietnamese then thanked the Americans for the conference, and in turn some of the senior members of the American delegation—in order, Admiral Sharp, Leonard Marks, General Wheeler, Ambassador Lodge, Ambassador Harriman—made brief statements about the meaning of the conference. The President then made his final statement:
. . . Preserve this communiqué, because it is one we don’t want to forget. It will be a kind of bible that we are going to follow. When we come back here 90 days from now, or six months from now, we are going to start out and make reference to the announcements that the President, the Chief of State and the Prime Minister made in paragraph 1, and what the leaders and advisors reviewed in paragraph 2. . . . You men who are responsible for these departments, you ministers, and the staffs associated with them in both governments, bear in mind we are going to give you an examination and the finals will be on just what you have done.
In paragraph 5; how have you built democracy in the rural areas? How much of it have you built, when and where? Give us dates, times, numbers.
In paragraph 2; larger outputs, more efficient production to improve credit, handicraft, light industry, rural electrification—are those just phrases, high-sounding words, or have you coon-skins on the wall. . . .
Next is health and education, Mr. Gardner. We don’t want to talk about it; we want to do something about it. “The President pledges he will dispatch teams of experts.” Well, we better do something besides dispatching. They should get out there. We are going to train health personnel. How many? You don’t want to be like the fellow who was playing poker and when he made a big bet they called him and said “what have you got?” He said “aces” and they asked “how many” and he said “one aces”. . . .
Next is refugees. That is just as hot as a pistol in my country. You don’t want me to raise a white flag and surrender so we have to do something about that. . . .
Growing military effectiveness: we have not gone in because we don’t want to overshadow this meeting here with bombs, with mortars, with hand grenades, with “Masher” movements. I don’t know who names your operations, but “Masher.” I get kind of mashed myself. But we haven’t gone into the details of growing military effectiveness for two or three reasons. One, we want to be able honestly and truthfully to say that this has not been a military build-up conference of the world here in Honolulu. We have been talking about building a society following the outlines of the Prime Minister’s speech yesterday.
Second, this is not the place, with 100 people sitting around, to build a military effectiveness.
Third, I want to put it off as long as I can, having to make these crucial decisions. I enjoy this agony. . . . I don’t want to come out of this meeting that we have come up here and added on X divisions and Y battalions or Z regiments or D dollars, because one good story about how many billions are going to be spent can bring us more inflation that we are talking about in Vietnam. We want to work those out in the quietness of the Cabinet Room after you have made your recommendations, General Wheeler, Admiral Sharp, when you come to us. . . .

Memo on Pentagon Meeting Following up Honolulu Session
Excerpts from memorandum by Richard C. Steadman, special assistant to Secretary of Defense McNamara, Feb. 9, 1966, summarizing a Pentagon meeting after the Honolulu talks. According to Mr. Steadman the participants included the Secretary, his deputies, the secretaries of each of the armed services and other Defense Department officials.
. . . 3. Southeast Asia Program Office. It is essential that the Department of Defense has at all times a readily available and centralized bank of information with respect to the Southeast Asia build-up. To this end. Dr. Enthoven is to establish a Southeast Asia Program Office which is to be able to furnish Mr. McNamara and Mr. Vance all information that may be required with respect to Southeast Asia. Among other things, this unit is to be able to provide immediate information on what overseas units are being depleted in order to accommodate Southeast Asia needs. If there is any drawdown anywhere, Mr. McNamara wants to know it promptly. We must know the full price of what we are doing and propose to do.
Mr. McNamara suggested that each Service Secretary establish a similar Southeast Asia Program Unit to bring together and keep current data relating to that Service involving Southeast Asia, and that the Joint Staff might establish a similar set-up.
Mr. McNamara said that it was mandatory that the situation be brought under be
tter control. For example, the Southeast Asia construction program was $1.2-billion in the FY 66 Supplement; yesterday at Honolulu the figure of $2.5-billion was raised. Yet there is only the vaguest information as to how these funds will be spent, where, on what, and by whom. This is part of the bigger problem that there is no proper system for the allocation of available resources in Vietnam. McGeorge Bundy is to help organize the country team to deal with this problem, including reconciling military and non-military demands.
4. Manpower Controls. Mr. McNamara designated Mr. Morris as the person to be responsible for the various manpower requirements. He is either to insure that the requirements are met or to let Mr. McNamara know if they are not being met. Mr. McNamara wants a written statement whenever we have been unable to do something that General Westmoreland says he needs for full combat effectiveness. (In this regard, General Westmoreland recognizes that it is not possible to have 100 percent combat effectiveness for all the 102 battalions. For example, there are not sufficient helicopter companies. Roughly, he estimates he will get 96 battalion combat effectiveness out of the 102 battalions.)
At this point there was a brief discussion concerning the use of U.S. troops for pacification purposes. Mr. Nitze indicated that in his view the Marines were doing this to some degree. The point was disputed. At any rate, Mr. McNamara said that the 102 combat battalions contemplated under Case 1 were not to be used for pacification but only for defense of base areas and offensive operations. Mr. McNamara outlined briefly the South Vietnamese Government’s plan for pacification. It will affect some 235,000 people in the whole country. The major allocation of resources and personnel will be to four very limited areas, one of which is near Danang. There will also be a general program extending throughout the country involving some 900 hamlets.
5. Call-Up of Reserves. Mr. McNamara said that it was important that everyone understand why a Reserve call-up is receiving such careful study. There are at least two important considerations. First, the problem is a very complicated one and we do not yet have all the facts. Mr. Morris and others will amass the necessary data as soon as possible. Second, the political aspects of a Reserve call-up are extremely delicate. There are several strong bodies of opinion at work in the country. Look, for example, at the Fulbright Committee hearings. One school of thought, which underlies the Gavin thesis, is that this country is over-extended economically and that we cannot afford to do what we are doing. Another school of thought feels that we plain should not be there at all, whether or not we can afford it. A third school of thought is that although we are rightly there, the war is being mismanaged so that we are heading straight toward war with China. Furthermore, there is no question but that the economy of this country is beginning to run near or at its capacity with the resulting probability of a shortage of certain skills and materials. If this continues we may be facing wage and price controls, excess profits taxes, etc., all of which will add fuel to the fire of those who say we cannot afford this. With all these conflicting pressures it is a very difficult and delicate task for the Administration to mobilize and maintain the required support in this country to carry on the war properly. The point of all this is to emphasize that a call-up of the Reserves presents extremely serious problems in many areas and a decision cannot be made today.
General Johnson said he wished to add three additional considerations. First, a Reserve call-up might be an important factor in the reading of the North Vietnamese and the Chinese with respect to our determination to see this war through. Second Reserve call-ups are traditionally a unifying factor. Third, as a larger problem, a hard, long-term look should be taken at the degree to which we as a government are becoming committed to a containment policy along all the enormous southern border of China. Mr. McNamara said he would ask for a JCS study of this last point and discussed it briefly.
During the course of the meeting, General Johnson also pointed out that with respect to overseas deployment, the Army is already shortchanging certain overseas areas so as to increase the training cadres in CONUS. He pointed out that because of the effect on the strategic reserve of deployments already made, the quality of new units will be lower than at present. He raised certain additional points affecting the Army. Mr. McNamara, Mr. Vance, Mr. Resor and General Johnson will discuss these problems further. . . .

Rostow’s Memo on Bombing of Hanoi’s Petroleum Facilities
Excerpt from memorandum from Walt W. Rostow, Presidential assistant for national security, to Secretary of State Rusk and Secretary of Defense McNamara, May 6, 1966, as provided in the body of the Pentagon study. Paragraphs in italics are the study’s paraphrase or explanation.
Rostow developed his argument for striking the petroleum reserves on the basis of U.S. experience in the World War II attacks on German oil supplies and storage facilities. His reasoning was as follows:
From the moment that serious and systematic oil attacks started, front line single engine fighter strength and tank mobility were affected. The reason was this: It proved much more difficult, in the face of general oil shortage, to allocate from less important to more important uses than than the simple arithmetic of the problem would suggest. Oil moves in various logistical channels from central sources. When the central sources began to dry up the effects proved fairly prompt and widespread. What look like reserves statistically are rather inflexible commitments to logistical pipelines.
‘The same results might be expected from heavy and sustained attacks on the North Vietnamese oil reserves,
With an understanding that simple analogies are dangerous, I nevertheless feel it is quite possible the military effects of a systematic and sustained bombing of POL in North Vietnam may be more prompt and direct than conventional intelligence analysis would suggest.
I would underline, however, the adjectives “systematic and sustained.” If we take this step we must cut clean through the POL system—and hold the cut—if we are looking for decisive results. . . .

Joint Chiefs’ Order to Begin Bombing of Hanoi’s Oil Facilities
Joint Chiefs of Staff’s cablegram to Adm. U. S. Grant Sharp, commander in chief of Pacific forces, June 22, 1966, as provided in the body of the Pentagon study.
Strikes to commence with initial attacks against Haiphong and Hanoi POL on same day if operationally feasible. Make maximum effort to attain operational surprise. Do not conduct initiating attacks under marginal weather conditions but reschedule when weather assures success. Follow-on attacks authorized as operational and weather factors dictate.
At Haiphong, avoid damage to merchant shipping. No attacks authorized on craft unless U.S. aircraft are first fired on and then only if clearly North Vietnamese. Piers servicing target will not be attacked if tanker is berthed off end of pier.
Decision made after SecDef and CJCS were assured every feasible step would be taken to minimize civilian casualties would be small [sic]. If you do not believe you can accomplish objective while destroying targets and protecting crews, do not initiate program. Take the following measures; maximum use of most experienced ROLLING THUNDER personnel, detailed briefing of pilots stressing need to avoid civilians, execute only when weather permits visual identification of targets and improved strike accuracy, select best axis of attack to avoid populated areas, maximum use of ECM to hamper SAM and AAA fire control, in order to limit pilot distraction and improve accuracy, maximum use of weapons of high precision delivery consistent with mission objectives, and limit SAM and AAA suppression to sites located outside populated areas.
Take special precautions to insure security. If weather or operational considerations delay initiation of strikes, do not initiate on Sunday, 26 June.

August McNamara Memo to Chiefs Challenging Troop Request
Memorandum, “CINCPAC CY 1966 Adjusted Requirements & CY 1967” from Secretary McNamara to the Joint Chiefs of Staff Aug. 5, 1966, as provided in the body of the Pentagon study.
&n
bsp; As you know, it is our policy to provide the troops, weapons, and supplies requested by General Westmoreland at the times he desires them, to the greatest possible degree. The latest revised CINCPAC requirements, submitted on 18 June 1966, subject as above, are to be accorded the same consideration: valid requirements for SVN and related tactical air forces in Thailand will be deployed on a schedule as close as possible to CINCPAC/ COMUSMACV’s requests.
Nevertheless, I desire and expect a detailed, line-by-line analysis of these requirements to determine that each is truly essential to the carrying out of our war plan. We must send to Vietnam what is needed, but only what is needed. Excessive deployments weaken our ability to win by undermining the economic structure of the RVN and by raising doubts concerning the soundness of our planning.
In the course of your review of the validity of the requirements, I would like you to consider the attached Deployment Issue Papers which were prepared by my staff. While there may be sound reasons for deploying the units questioned, the issues raised in these papers merit your detailed attention and specific reply. They probably do not cover all questionable units, particularly for proposed deployments for the PACOM area outside of SVN. I expect that you will want to query CINCPAC about these and other units for which you desire clarification.
I appreciate the time required to verify the requirements and determine our capability to meet them, but decisions must be made on a timely basis if units are to be readied and equipment and supplies procured. Therefore I would appreciate having your recommended deployment plan, including your comments on each of the Deployment Issue Papers, no later than 15 September 1965.
