INTRODUCTION Any military commander who's honest with himself will admit that he has
made mistakes in the application of military power. He's killed people,
unnecessarily; his own troops or other troops, through mistakes, through
errors of judgment. A hundred, or a thousand, or tens of thousands, maybe
even a hundred thousand, but he hasn't destroyed nations... and the
conventional wisdom is 'don't make the same mistake twice, learn from your
mistakes'. And we all do. Maybe we make the same mistake three times, but
hopefully not four or five.
There will be no learning period with nuclear weapons. You make one
mistake and you're gonna destroy nations.

The atomic bombs that the United States dropped on Hiroshima and Nagasaki on
August 6 and August 9, 1945 had not the sole consequence of definitively ending World
War II, but also propelled the world into a new era. In time, nuclear weapons
dramatically changed the way great power confrontations would be handled. The first
years of the Nuclear era witnessed a preponderance of the classic military techniques
applied to nuclear weapons 2
. The Doctrine of strategic bombardment applied to nuclear
weapons would quickly lead the United States to develop war plans envisioning a level
of destructiveness without precedent.
3
Soon enough, the political establishment and to
some extent the military started to understand that nuclear weapons made military
victory impossible. In a hypothetical nuclear confrontation, both adversaries could only

achieve limited political goals, allowing space only for political victory.
4
By the early
1960s, the Cold War confrontation reached a stage were both adversaries possessed
immensely powerful weapons, but were mutually vulnerable to each other's attack. This
stage of nuclear confrontation took the somehow unfortunate name of MAD – Mutual
Assured Destruction 5
.
The process leading from Hiroshima and Nagasaki to MAD embodies both the history
of the Cold War – and therefore international relations – and the history of American
policy-making on nuclear weapons. In this dissertation, I focus on the role of “civilian
advisors” in shaping American nuclear policies. The term “civilian advisors” refers to
all the people that offered their counsel or their services in correlation with nuclear
weapons to the administration, but that were neither military professionals nor elected
officials. This category includes, for example, scientists, businessmen, administrators
and private citizens. The origins of their influence on nuclear policies can be traced
back to the Wartime Manhattan Project, the massive American effort towards the
development of a nuclear bomb.
The three-year-long effort of the Manhattan Project that culminated in the delivery of a
functional atomic bomb had mobilized an array of civilians, mostly scientists, to work
on the construction of the bomb. These civilians soon became aware of the
revolutionary nature of the work they were doing. They realized that atomic weapons
would have an incredible destructive power and would carry revolutionary changes in a
number of fields, not only in war-making. They therefore became engaged in a lobbying
effort to try to advise and influence the Administration's actions regarding nuclear
energy and atomic weapons.
The actions of the Manhattan scientists represented the first effort by civilian advisors to
influence the Government's policy on nuclear weapons. It is unsurprising that this effort
came from them, as they were the only people outside the military and the highest
echelons of the Administration to be aware of the atomic project. Slowly but steadily,
information about nuclear power and its military and civilian applications became
available. Therefore, a great number of civilians, not only scientists, became interested
in nuclear issues and decided to offer their contribution to the Administration. Whether
by informal advice or formal participation in governmental institutions, civilian advisors

5 On MAD, see Jervis (1989), op. cit., 74-106

were at the forefront in the formulation of nuclear policies throughout the Nuclear era.
This dissertation will try to analyze the role of these advisors during the first three
Administrations of the Nuclear Era – namely the Truman, Eisenhower and Kennedy
Administrations. This time-frame covers the events leading from the use of the first
nuclear bomb on Hiroshima on August 6, 1945 to the signing of the Limited Test Ban
Treaty in August 1963. There are four major reasons to justify the decision to limit the
analysis to these 18 years. These reasons are inextricably linked to events and choices
occurred during the Kennedy Administration:
1. Kennedy brought civilian advice from the sidelines of Government directly to
the center of decision-making. The appointment of Robert McNamara and others
to central positions of power within the administration took the relationship
between policy-making and civilian advisors to a whole other level than his
predecessors, and Kennedy's example will be followed by his successors;
2. The 1963 Test Ban Treaty was the first meaningful agreement between the
superpowers on the limitation of the use of nuclear weapons. While some
authors argue that the LTBT was a missed opportunity for détente 6
, I tend to
consider this treaty as the first stepping stone into a new era of East-West
relations;
3. The Cold War confrontation changed its focus from military power to
ideological influence. Kennedy's “New Frontier” signaled that the United States
had decided to respond to Soviet efforts in the third world by engaging in
limited, local and delegate warfare to counter Soviet ideological expansion.
American involvement in Laos and Vietnam, and the Bay of Pigs fiasco are
evidence of this new effort. The war was again to be fought on the battleground;
4.The Cuban missile crisis led the world to the brink of nuclear war and utter
destruction. Consequently, both the United States and the Soviet Union became
more conscious about the risks of nuclear warfare and about the need to avoid a
nuclear escalation at any cost.
The analysis will revolve around some of the major turning points in the history of
nuclear weapons. In dealing with the Truman Administration, we will describe the
administration's efforts to gain international control of atomic energy and the role of the

Manhattan scientists in proposing it. We will see how internal control of atomic energy
was delegated to a civilian rather than military authority and how this affected policy-
making thereafter. We will then analyze the American reaction to the loss of their atomic
monopoly in 1949 and the controversial decision to proceed with the development and
testing of the thermonuclear bomb. During the Eisenhower administration, we will see
how new efforts towards and international agreement on nuclear weapons originated
from civilian advisors, but were sidetracked to suit the interests of some members of the
Administration. We will then examine the infamous Oppenheimer hearing and its
consequences on scientific advice. Finally, we will see how the technological evolution
of the American nuclear arsenal was lead by civilian advisors. Regarding Kennedy, we
will explore the origins of the new strategy of flexible response and investigate the
process that led to the signing of the LTBT.
In all of these events, the analysis will focus first on the decision-making process that
led to important policy choices, and then on the consequences of these choices on the
international environment of the Cold War. I will make substantial use of primary
sources, such as the documents collected in Foreign Relations of the United States,
unclassified documents available on-line and personal accounts of the persons involved.
Where possible, I will use quotations to convey the original sense of the words as they
were intended by the authors. Lastly, I also referred to the works of qualified scholars to
address interpretative issues.
Obviously, the scope of this work required difficult choices on which issues should be
included and which should not. My goal is not that of offering a complete and thorough
analysis of the role of every civilian advisor, but to analyze single relevant episodes and
highlight the influence civilian advisors have had. In the conclusions, I will offer a
tentative categorization of the relationship of each President to civilian advice. I will
also try to explain the nature and the reasons for the changes that incurred in the
relationship between civilian advisors and policy-making in the 18 years I examined.

CHAPTER 1:
THE TRUMAN ADMINISTRATION When Harry S. Truman succeeded Franklin Delano Roosevelt and became the 33
rd
President of the United States of America, he had very limited knowledge of the
existence of the atomic bomb project. After the first cabinet meeting, the new President
was approached by Secretary of War Henry L. Stimson, who asked to speak with him
urgently. Stimson felt he had to inform him of “an immense project... looking to the
development of a new explosive of almost unbelievable power”; Truman already knew
that “something unusually important was brewing in our war plants”: when he was the
Chairman of the Special Committee to Investigate the National Defense Program, he
was approached by Stimson and asked not to investigate certain plants were “the
greatest project in the history of the world” was underway 1
. Nonetheless, Stimson's
briefing, along with Byrnes' the next day, left the President puzzled.
Only two weeks later, on April 25, did the President receive a full briefing on the matter
by Secretary of War Stimson and General Leslie R. Groves, the director of the
Manhattan Project. The Secretary of War stated that “w ithin four months we shall in all
probability have completed the most terrible weapon ever known in human history, one
bomb of which could destroy a whole city.” Furthermore, he described a series of
implications the development of the A-bomb would have on national and international
politics. First of all, Stimson warned that the imminent possession of the atomic weapon
had to be considered a momentary advantage, since other nations would sooner or later
be willing and able to build one of their own – Russia above all. Second, he noted how
“the question of sharing it [the A-bomb] with other nations and, if so shared, upon what
terms, becomes a primary question of our foreign relations”; similarly, any approach to
a world peace organization such as the United Nations could not disregard the role of
1 Truman, Harry S. (1955), Memoirs by Harry S. Truman, Vol. 1: Year of Decisions, Garden City :

7
atomic weapons, their destructiveness and the need to control them in the interest of
peace. Third, Stimson recognized that the development of the bomb by the United
States “has placed a certain moral responsibility upon us” and that the way the US
would handle it could either bring the world to disaster or save civilization.
2
The points made in Stimson's April 25
th briefing to the President provided a very sound
analysis of the situation the United States faced and described the conflicting issues that
Truman would have to deal with throughout his two terms: the need felt by the scientific
community to share information about atomic energy; the arms race that could develop
with the Russians; the possibility to stop this arms race through an international
arrangement of some sort and the implications that the President's choices would have
not only on American people, but on civilization as a whole.
During Truman's eight years in office, the United States faced four fundamental turning
points that decisively shaped American policy towards the atomic bomb: 1) The quest
for international control and the failure of the Baruch Plan; 2) The struggle for domestic
legislation; 3) The H-Bomb decision and the policy review resulting in NSC-68 and 4)
The decision to test the H-bomb. Each one of these turning points saw the intervention
of civilian advisors as proponents of policy or as in opposition to it.
1.1 BIRTH AND DEMISE OF INTERNATIONAL CONTROL The Struggle for international control started during the Roosevelt Administration and
was tightly intertwined with the issue of the relationship of the United States with their
allies. Roosevelt had decided early on to exclude the Russians from participation in –
and even knowledge about – the whole Manhattan project. The relationship with them
was already uneasy in 1941: the Soviet position in the war and their role as potential
liberators of Europe from the Nazi regime clashed with the signing of the Molotov-
Ribbentrop Pact two years earlier. Moreover, Stalin's voluble personality and the
dictatorial nature of his government could not reassure Roosevelt about the future
intentions of the Soviet dictator, especially if he could gain access to a weapon of mass

8
destruction. On the other hand, Roosevelt decided to keep a tighter relationship with
Great Britain and Canada. The United States carried on a policy of complete
interchange of information about nuclear research with Great Britain up until December
27, 1942, when word reached Roosevelt of a loosely framed agreement between Great
Britain and the Soviet Union that called for the exchange of new weapons. This event
embittered Anglo-American relations and also strengthened the position of two of
Roosevelt's most important advisers on atomic matters: Vannevar Bush and James B.
Conant.
Vannevar Bush, director of the Office of Scientific Research and Development (OSRD)
and President of the Carnegie Foundation, had been the driving force responsible for the
development of the atomic project. Bush had convinced Roosevelt to invest on atomic
energy research and the potential military uses of it 3
; he was therefore considered “the
leading administrator of science in the country” 4
, the liaison between the scientific
community and the decision-making levels of government together with his close
colleague James B. Conant, President of Harvard University and director of the National
Defense Research Committee (NDRC).
Bush and Conant “did not want British industry to benefit from American nuclear
research and feared that Roosevelt might be exceeding his constitutional authority by
sharing those secrets that the British could exploit only after the end of the war” 5
.
Reason for this was that it would have been easier to maintain secrecy if only the
information strictly necessary for nuclear materials’ basic production were shared. All
the information regarding the design of the bomb, then, would be kept secret 6
.
The December 28, 1942 decision to limit scientific interchange seemed to favor the
Bush-Conant position. However, the scientists were soon to be disappointed by the
signing of the Quebec Agreement on August 19, 1943, that mandated yet again a policy
of full interchange of technology between the three signatories, the U.S., Great Britain
and Canada, and the continuation of the secrecy policy towards the Soviet Union. After

the signing of the agreement, Bush and Conant were excluded from the governmental
decision-making process and were precluded direct access to the President.
Consequently, no presidential advisor was left to push for a long-term approach to
nuclear matters, while Roosevelt focused only on the war effort and on how to use the
Bomb effectively.
The first person to bring Roosevelt's attention back to postwar planning was
distinguished Nobel laureate in physics Niels Bohr, who approached Churchill and
Roosevelt between May and August 1944 with a plan to reveal the project of the bomb
to Stalin and start negotiations on international control. Although Roosevelt expressed
interest in the Plan in a meeting with the scientist, he actually moved towards a firmer
Anglo-American nuclear monopoly.
7
Bohr's plan was probably too ambitious to have
any possibility of being accepted, but the rationale behind his idea was appealing to
Bush and Conant, who were also thinking that an overture to the Russians was
necessary. Since they had had no access to the President in the preceding year, they
decided to change their approach strategy: instead of reaching out directly to the
President, they would try to influence Secretary of War Stimson by drafting
memoranda for him, with the ultimate goal of convincing him to support their view in
the highest echelons of government.
The new Bush-Conant strategy bore the first fruits during Stimson's meeting with
Roosevelt on March 15, 1945. During this meeting, which happened to be the last time
Stimson ever saw the President, the Secretary of War had the chance to illustrate the
timetable for the bomb and point out how a decision about the future of atomic energy
had to be made as soon as possible. Stimson argued that there were two schools of
thought on the matter. The first one favored continuation of secrecy and an attempt by
the U.S. and Great Britain at retaining a monopoly on nuclear weapons; The other called
for free interchange of scientific information based on the internationalization of nuclear
weapons. Roosevelt agreed with Stimson's analysis, yet failed to respond to it 8
; it was a
partial victory for Bush and Conant, but it was a short lived one: Roosevelt died few
weeks later, on April 12, 1945, apparently leaving the two scientists at the starting point
again.

10
Truman's installation as the new President did not, in fact, interrupt Bush and Conant's
initiative. As recalled before, Stimson briefed the new President on April 25, 1945
pointing out the key questions raised by atomic energy. Truman appreciated the analysis
offered by the Secretary of War, but also appreciated the position held by another
member of his cabinet, the soon to become secretary of state Byrnes, who thought that
the bomb could “put us in a position to dictate our own terms at the end of the war” 9
.
Hence a tension arose between two different approaches inside the administration: on
one side, Stimson's ideas about international control and the moral responsibility of the
United States; on the other, Byrnes' proposal to use atomic diplomacy to gain an
advantage in postwar negotiations. Considering these different points of view, Truman
decided to endorse Stimson's proposal to establish an Interim committee that would
study “temporary war controls and... postwar research, development and controls” 10
.
The Committee, chaired by Stimson himself, also included George Harrison, an
assistant to the Secretary of War; Conant; Bush; Karl Compton, president of MIT; Ralph
Bard, undersecretary of the navy; William L. Clayton, undersecretary of state; and
James F. Byrnes, special representative to the President and soon to become secretary of
state. The Committee immediately decided to nominate an advisory scientific Panel
composed of J. Robert Oppenheimer, director of the Los Alamos laboratory; Arthur
Compton, director of the Chicago Metallurgic Laboratory; Ernest Lawrence; and Enrico
Fermi.
The issues discussed by the Interim committee were essentially four
11
:
1. The possible use of the atomic bomb against Japan;
2. The decision to inform the Soviet Union;
3. Domestic legislation;
4.Possible measures of international control.
The advisability of informing the Soviet Union and the possibility of devising measures
of International control were tightly related issues. They first surfaced during the May
18 meeting, as the Committee discussed the Bush-Conant estimates on the time needed
by the Soviet Union to catch up on the U.S. and build a bomb on their own. The
scientists argued that three to four years would have been sufficient for the Soviets to

political and economic matters, U.S. Government Printing Office, 1967 (hereafter, FRUS with
appropriate year, volume, and page numbers), 11-12
11
catch up, while General Groves considered twenty years a more realistic figure.
12
If the
Soviet Union was lagging far behind, as suggested by Groves, there would be no
incentive to reveal any information to the Soviets; on the other hand, if Moscow was
only a couple of years away from their own bomb, an effort towards Soviet-American
cooperation had to be taken into consideration. The Committee's decision to trust
General Groves' estimates, rather than Bush and Conant's, put a momentary halt to any
proposal to approach the Russians.
13
The issue resurfaced on May 31, when the advisory scientific panel was invited to
attend the Interim Committee meeting. The discussion initially focused on the
consequences of the use of an atomic weapon during the war and the subsequent issue
of maintaining secrecy about its development. Arthur Compton reported that “the
members of the Scientific Panel were unanimous in the opinion that so many persons
already knew about the wartime atomic studies that soon after the war it would be
common knowledge that nuclear energy could be released and that it could not be long
before an atomic explosion would somewhere be tried”.
14
Oppenheimer took the opportunity to propose once again free interchange of
information with other nations, in order to create a free and co-operative international
community of scientists. He was convinced that the Americans were prejudging the
Soviet attitude and that cooperation with the Russians was possible. Byrnes intervened
resolutely at this point, arguing that the greatest risk for the U.S. was that if the Russians
were informed, Stalin would ask to join the partnership. He insisted that the only
possible strategy was to push research and production and make sure the U.S. stayed
ahead.
15
The logical consequence of the Committee's discussions was the recommendation
delivered June 6 to the President that no information should be disclosed to the Russians
until the first bomb was dropped. Moreover, a scantily framed proposal for international
control was presented, calling for an international control committee that would inspect
nuclear plants all over the world and ensure transparency of each Country's research and
facilities.
16
The recommendation reflected Stimson's and Byrnes' persistent wariness

12
about Stalin's intentions, while basically ignoring the scientists' point of view.
The Committee's decision was soon challenged by a report drafted by a group of
scientists working at the Chicago Metallurgical Project known as the Franck Report.
The scientists' argument rested on two propositions:
17
1. Maintaining secrecy about scientific information and controlling the supply of
raw materials would not stop a nuclear arms race;
2. When such an arms race would occur – that is, as soon as the first nuclear bomb
is used - the United States would be at a disadvantage in comparison to other
nations whose population and industry were less centralized.
The consequence of these propositions provided that the only hope to avoid an arms
race lied in International control. To achieve this, though, the United States would have
to renounce the direct military use of nuclear weapons:
the military advantages and the saving of American lives, achieved by the sudden
use of atomic bombs against Japan, may be outweighed by the ensuing loss of
confidence and wave of horror and repulsion, sweeping over the rest of the world,
and perhaps dividing even the public opinion at home. From this point of view a
demonstration of the new weapon may best be made before the eyes of
representatives of all United Nations, on the desert or a barren island.
18
The Report was submitted to Arthur Compton on June 11 and was in turn discussed by
the members of the scientific Panel. The Report never reached the Interim Committee
directly and never received the careful consideration it required 19
. However, Compton
got a chance to present its content to the Committee on June 21, but was met by
skepticism. Regarding the proposal of a demonstrative strike, the scientific panel
declared that they could “propose no technical demonstration likely to bring an end to
the war” and could “see no acceptable alternative to direct military use” 20
; thus the
Committee reaffirmed the need for a timely and effective strike without warning.
On the other hand, the recommendation to inform the allies before using the bomb
found a more welcoming audience in the scientific Panel and especially in Bush and

Conant; after a lengthy discussion, the Committee agreed that informing Stalin about
the A-bomb in the coming Big Three meeting would have been advantageous for the
United States and might produce Soviet cooperation.
21
Stimson, who had not been present at the June 21 meeting, was readily briefed by
Harrison on June 26. Stimson in turn briefed the President on the recommendations
delivered by the Interim Committee, particularly stressing the need to tell Stalin that the
United States were working on the bomb.
On July 24 Truman approached Stalin during the Potsdam conference and “casually
mentioned that we had a new weapon of unusual destructive force”. The Russian
dictator didn't show much interest, probably because he already knew about the bomb
through his spies 22
, but said “he was glad to hear it and hoped we would make 'good use
of it against the Japanese' ”.
23
The exceptionally indirect way in which Truman decided
to pass this fundamental piece of information to Stalin is puzzling. Scholars
substantially agree that Truman decided to take the minimal step, revealing only enough
information to avoid Soviet accusations of being non-collaborative after the bomb was
dropped, but failed to take the chance and lay the ground for future cooperation;
24
Truman's failure to follow Stimson's advice can be considered a missed opportunity to
start an effort aimed at international control of atomic energy, but it is nonetheless
doubtful that Stalin would have agreed with it.
August 6 and August 9, 1945 are two dates forever inscribed in human history. The only
atomic bombs ever used in combat were dropped on the cities of Hiroshima and
Nagasaki, causing hundreds of thousands of Japanese civilian casualties and forcing
Japan to finally surrender. The successful completion and delivery of the atomic bomb
meant the end of a bloody war that could have been even costlier if US troops were
forced to invade the Japanese mainland, but it also meant that a wartime project now
had to find its peacetime role. The future of the atomic bomb was now the present and
the administration had no plan about peacetime control. Thus a new sense of urgency
arose in the members of the Administration to develop a coherent strategy to deal with
the issue.
