CHURCH COMMITTEE REPORTS

E. DIEM
1. SU~nIARY
South Vietnamese President Ngo Dinh Diem and his brother, Ngo
Dinh Nhu, were assassinated during a coup by Vietnamese generals on
November 2, 1963. Evidence before the Committee indicates that the
United States government offered encouragement for the coup, but
neither desired nor was involved in the assassinations. Rather, Diem's
assassination appears to have been a spontaneous act by Vietnamese
generals, engendered by anger at Diem for refusing to resign or put
himself in the custody of the leaders of the coup.
On one occasion, General Duong Van Minh ("Big Minh") outlined
to a CIA officer the possible assassination of Nhu and another brother,
Ngo Dinh Can, as one of three methods being considered for changing
the government in the near future. Ambassador Henry Cabot Lodge
and Deputy Chief of Mission ·William Trueheart 1 were informed of
this possibility by the Saigon Chief of Station, who recommended that
"we do not set ourselves irrevocably against the assassination plot,
since the other two alternatives mean either a bloodbath in Saigon or a
protracted struggle which would rip the Army and the country
assunder." (CIA cable, Saigon Station to DCI. 10/5/63) Upon being
informed, Director McCone sent two cables. The first stated "[w]e
cannot be in the position of stimulating, approving, or supporting assassination,"
and the second directed that the recommendation be withdrawn
because "we cannot be in position actively condoning such
course of action and thereby engaging OUr responsibility therefor."
(CIA cable, DCI to Saigon, 10/5/63; CIA cable, Dei to Saigon,
10/6/63)
2. THE ABORTIVE COUP OF AUGUST 19t>3
On May 8, 1963, South Vietnamese troops in the City of Hue fired
on Buddhists celebratin!! Buddha's birthday (and carrying the Buddhist
flag contrary to edicts proscribing the flying of religIOUS flags)
killing nine and wounding fourteen. This incident triggered a nationwide
Buddhist protest and a sharp loss of popular confidence in the
Diem regime.2
On May 18, United States Ambassador Frederick E. Nolting met
with Diem and outlined steps which the United States desired him to
take to redress the Buddhist grievances and recapture public confi-

dence. These steps included admitting responsibility for the Hue incident,
compensating the victims, and reaffirming religious equality
in the country. On June 8, Madame Nhu, the wife of Diem's brother,
Nhu, publicly accused the Buddhists of being infiltrated with Communist
agents. Trueheart, in the absence of Ambassador Nolting protested
her remarks to Diem and threatened to disassociate the United
States from any repressive measures against the Buddhists in the future.
(Pentagon Papers, p. 308) Shortly thereafter, Madame Nhu commented
on the self-immolation of Quang Duc and other Buddhist
monks by stating that she would like to furnish mustard for the monks'
barbecue. On June 12, Trueheart told Diem that Quang Due's suicide
had shocked the world and again warned that the United States would
break with his government if he did not solve the Buddhist problem.
(Pentagon Papers, p. 208) .
Lucien Conein, a CIA officer in Saigon,l testified that the Buddhist
uprisings were the catalyst that ultimately brought down the D!em
regime. (Conein, 6/20/75, pp. 42-44) These events led the Umted
States to apply "direct, relentless, and tablehammering pressure on
Diem such as the United States has seldom before attempted with a
sovereign friendly government." (Mecklin, p.169)
By July 4,1963, Generals Minh, Don, Kim, and Khiem had agreed
on ,the necessity for a coup.2
In his final meeting on August 14 with Ambassador Nolting, Diem
agreed to make a public statement offering concessions to the Buddhists.
This statement took the form of an interview with the columnist,
Marguerite Higgins, in which Diem asserted. that his poUcy toward
the Buddhists had always been conciliatory and asked for harmony and
support of the government.
Shortly after midnight on August 21, 1963, Nhu ordered forces loyal
to him to attack pagodas throughout Vietnam, arresting monks and
sacking the sacred buildings. Over thirty monks were injured and
1,400 arrested. The American Embassy was taken by surprise and
viewed the attacks as a shattering repudiation of Diem's promises to
Nolting. (Pentagon Papers, p. 210)3
On August 24, 1963, the State Department sent a cable (Deptel 243 )
to the new Ambassador in Vietnam, Henry Cabot Lodge. The telegram
was prepared by Roger Hilsman, Assistant Secretary of State
for Far Eastern Affairs, and Under Secretary of State Averell Harriman,
and was approved by President Kennedy. (Pentagon Papers, p.
235) Deptel 243 told Lodge to press Diem to take "prompt dramatic
actions" to redress the grievances of the Buddhists:
We must at same time also tell key military leaders that US would find it
impossible to continue support GVN [South Vietnamese Government] militarily
and economically unless above steps are taken immediately which we recognize re-
1 Conein testified that he had known the generals involved In the coup "for many
years. Some of them I had known back even In World War II. Some of them were in
powerful positions, and I was able to talk to them on a person to person basis, not as a
government official." (Coneln, 6/20/75, p. 17.)
2 Conein'~ After-Action R~port stated that: "The majority of the officers, Including
General MInh, desired President Diem to have honorable retirement from the political
scene In South Vietnam aad exile. As to Ngo Dinh Nhu and Ngo Dlnh Can, there was
never dissention. The attitude was that their deaths, along with Madame Ngo Dinh Nhu,
would be welcomed" (Coneln After-Action Report, 11/1/63, p. 10.)
3 Coneln testified that the raids might have been timed to occur when no American
Ambassador was In Vietnam (Nolting had left a few days before and his replacement
Henry Cabot Lodge, had not yet arrived) (Conein, 6/20/75, p. 21). '
219
quires removal of the Nhus from the scene. We wish give Diem reasonable
opportunity to remove Nhus but if he remains obdurate, then we are prepared to
accept the obvious implication that we can no longer support Diem. You may also
tell appropriate military commanders we will give them direct support in any
interim period of breakdown central government mechanism * * *. Concurrently
with above, Ambassador and country teams should urgently examine all possible
aIte-mati'Ve leadeI"Ship and make detailed plans as to how we mIght bring about
Diem's replacement if this shou'ld become necessary.
A cable on August 25 reported the result of a conference among
a station representati"e, Lodge, Trueheart, General Harkins [Commander,
Milit:<ry Assistance Cummand, Vietnam (MACV)] and
General Weede (Chief of Staff, MACV). They accepted Deptel 243
"as a basic decision from 1Vashington and would proceed to do their
best to carry out instructions," (I.G. Report, C, pp. 7-8) but believed
that Diem would refuse to remove his brother from his position in the
government.
Early in the morning of August 26, 1963, the Voice of America in
South Vietnanl placed the blame on Nhu for the August 21 raids and
absolved the army. The broadcast also reported speculation that the
Fnited States contemplated suspending aid to the South Vietnamese
Government.1 (Pentagon Pa-pers, p. 212) Later on that same day,
Lodge presented his credentials to Diem. CI<A officer O:mmn and
another CIA officer were told to see Generals Khiem and Khanh,
respectively, and to convey to them the substance of Deptel 243, but
to remind them that "We cannot be of any help during initial action
of assuming power of state. Entirely their own action, win or lose."
(DCI to Saigon, 8/26/63). .
A. message from the White House on August 29 authorized Harkins
to confirm to the Vietnamese generals that the United States would
support a coup if it had a good chance of succeeding, but did not
involve Fnited States armed forces. Lodge was authorized to suspend
United States 'aid at his discretion. (DepOOl 272, 8/00/63) A ooble
from the President to Lodge on the same day stated:
I have approved all the messages you are receiVing from others today, and I
emphasize that everything in these messages has my full support. We will do
all 'that we can to hel,p you oonclude this operation successfully. Until tJhe very
matnent of the go signal for the operation by the Generals, I must reserve a
contJingent right to ch'ange course a:nd reverse previous inmrncifJion'S. While fully
aWlI;re of your assessment of the consequences of such a revergal, I kn:ow from
experien'ce that faIlure is more destructive than an appeal"ance of indecisllon.
I would, of course, accept full responsibility for any such change as I must also
bear the full responsibility for this operation and its consequences. (Cablp,
President Kennedy to Lodge 8/29/63)
In a reply cable, Lodge stated:
1. I fully under;:tand that you have the right and re;:ponsibility to change
course at any time. Of course I will always re;:pect that right.
2. To be successful, this operation must be essentially a Vietnamese affair
with a momentum of its own. Should this happen you may not be able to control
it, I.e., the "go signal" may be given by the generals. (OIlIble, Lodge to President
Kennedy, 8/30/63)
1 In a cable to Harriman, Lodge complained that the VOA broadcast had "complicated
our alread~' difficult problem" by eliminating "the possibility of the generals' ell'ort achievIng
surprise." Lodge further warned that "the US must not appear publicly In the matter.
thus giving the 'kiss of death' to its friends" (Cable, Lodge to Harriman. 1S/26/63J.
220
A cable from Saigon dated August 31, 1963, stated:
This particU'tar coup is finished. ~neral[s did not feel ready and d'id not have
sufficient balance of forces. There is little doubt that GVN [South Vietnamese
Government] aware US role and may have considerable detaH. (CIA Gable, Sta.
to Hq. 8/31/63)
Deptel 243 and the VOA broadcast set the tone for later relations
between the United States representatives and the generals. Big Minh,
who had initial doubts about the strength of American support, grew
in confidence.
3. THE NOVEMBER 1963 COUP
American dissatisfaction with the Diem regime became increasingly
apparent. On September 8, AID Director David Bell, in a televisIOn
interview, stated that Congress might cut aid to South Vietnam if
the Diem government did not change its course. (Pentagon Papers,
p. 214) Lodge suggested a study to determine the most effective methods
of cutting aid to topple the regime. (Pentagon Papers, p.
214) On September 12, with White House approval, Senator Church
introduced a resolution in the Senate condemning the South Vietnamese
Government for its repressive handling of the Buddhist problem
and calling for an end to United States aId unless the oppressive
measures were curtailed. (Pentagon Papers, pp. 214-215)
In mid-September 1963, two proposals for dealing with Diem were
considered by the Administration. The first contemplated increasingly
severe pressure to bring Diem in line with American policy; the second
involved acquiescing m Diem's actions, recognizing that Diem and
Nhu were inseparable, and attempting to salvage as much as possible.
It was decided to adopt the first proposal, and to send Secretary of
Defense McNamara and General Taylor on a fact-finding mission to
Vietnam. (Pentagon Papers, p. 215)
On October 2, McNamara and Taylor returned to Washington and
presented their findings to the NatIOnal Security Council. Their report
confirmed that the military effort was progressing favorably, but
warned of the dangers inherent in the political turmoil and recommended
bringing pressure against Diem. This pressure would include
announcing the withdrawal of 1,000 American troops by the end of
the year, ending support for the forces responsible for the pagoda
raids, and continuing Lodge's policy of remaining aloof from the
regime. The report recommended against a coup, but suggested that
alternative leadership should be identified and cultivated. The recommendations
were promptly approved by the President. (Pentagon
Papers, pp. 215-216)
On October 3, Conein contacted Minh. Minh explained that a coup
was being planned, and requested assurances of American support if
it were successful. Minh outlined three courses of action lone of which
was the assassination of Diem's brothers, Nhu and Can. ('Gonein,
6/20/75, p. 25; cable, Saigon to Director, 10/5/63) The Station
cabled on October 5 that it had recommended to Lodge that "we do
not set ourselves irrevocably against the assassination plot, since the
other two alternatives mean either a blood bath in Saigon or a protracted
struggle." (Cable, Saigon to Director, 10/5/63)
1 The other courses of action were the encirclement of Saigon by various military units
and direct confrontation between military units involved in the coup and loya1!st units.
221
A cable from the CIA Director to Saigon responded that:
(W)e certainly eannot be in the position of stimUlating, approving, or supporting
assassination, but on the other hand, we are in no wa~' responsible for stopping
every such threat of whieh we might rec-eive even partial knowledge. We
certainly would not favor assassination of Diem. "'e believe engaging ourselves
by taking position on this matter opens door too easily for probes of our position
re others, re support of regime, et cetera. Consequently believe best approach is
hands off. "Rowever, we naturall~' interested in intelligence Oil any such plan." J
McCone testified that he met privately with the President and the
Attorney General, taking the position that "our role was to assemble
all information on intelligence as to what was going on and to report
it to the appropriate authorities. but to not attempt to direct it."
(McCone. fi/fi/7i). p. fi2) He belien~d the United States should maintain
a "hands off attitu(Ie." pfcCone. fi/6/75, p. (2) McCone testified:
I ft'It that tht' President agreed with my position, df>spite the fact that he had
great rt'sNvations ('oneNning Diem and his conduet. I urged him to try to hring
all the llressure Ive ('ould on Diem to change his ways, to encourage more support
throughout the coulltry. My preeise words to the President, and I remember them
very clearlJ', was that "Mr. President, if I was manager of a baseball team, I had
one pitcher, I'd keep him in the box whether he was a good pitcher or not." By
that I was saying that, if Diem was removed we would have not one coup but we
would have a succession of coups and political disorder in Vietnam and it might
last several years ann indeed it did. (MCCone, 6/6/7'5, pop. 62--63)
McCone stated that he did not discuss assassination with the President,
but rather "whether we should let the coup go or use our influences
not to." He left the meeting believing that the President agreed
with his "hands-off" recommendation. (McCone, 6/6/75, pp. 62-(3)
McCone cabled the Station on October 6 :
:\IcCone directs that you withdraw recommendation to ambassador (concerning
assassination plan) under McCone instructions, as we cannot be in position actively
condoning such course of action and thereby engaging our responsibility
therefore (Oahle, CIA to Saigon, 10/6/63)
In response, the CIA St,ation in Saigon cabled Headquarters:
Action taken as directed. In addition. since DUM Trueheart was also present
when original recommendation was made. specific withdrawal of recommendation
at :\IeCone's instruction was also conveyed to Trueheart. Ambassador Lodge commented
that he shares McCone's opinion. (Cable, Saigon to CIA, 10/7/63)
Conein, the CIA official who dealt directly with the Generals,2
testified that he was first told of McCone's response to the assassination
alternatiYe by Ambassador Lodge around October 20. (Conein,
6/20/75. p. 35) Conein testified (but did not so indicate in his detailed
After-Action Report) that he then told General Don that the United
States opposed assassination, and that the General responded, "AlriRht.
you don't like it, we \\,on't talk about it anymore." (Conein,
6/20/75, p. :16)
1 Colby, who was then Chief, Far Eastern Division. drafted this cable for McCone.
Colby testified:
"Q. 80 ~'ou were on notice as of that date that the Director personally opposed an~'
Inolvement by the CIA In an assassination?
"COLBY. I certainly was." (Colby. 6/20/i5. p. '57)
2 Coneln described his role as follows: "lily job was to convey the orders from my Ambassador
and the Instructions from my Ambassador to the people who were planning the
couP. to monitor those individuals who were planning the coup, to get as much Information
so that our government would not be caught with their pants down." (Coneln, 6/20/75,
pp. 38-39)
222
The United States increased pressure on Diem to mend his ways.
On October 17, General Richard Stillwell (MACV operations chief)
informed Secretary TIman that the United States was suspending aid
to the Special Forces units responsible for the pagoda raids until they
were transferred to the field and placed under ,Toint General Staff
(JGS) command. (Pentagon Papers, p. 217) On October 27, Lodge
traveled to Dalat with Diem, but did not receive any commitment from
Diem to comply with American requests. (Pentagon Papers, p. 219)
On October 28, Conein met with General Don, who had received
assurance from Lodge that Conein spoke for the United States. Don
said that he would make the plans for the coup available to the Ambassador
four hours before it took place, and suggested that Lodge not
change his plans to go to the United States on October 31. (I.G. Report,
C, p. 37; Pentagon Pa;pers, p. 219)
On October 30, Lodge reported to Washington that he was powerless
to stop the coup, and that the matter was entirely in Vietnamese
hands. General Harkins disagreed and cabled his opposition to the
coup to General Taylor. (Pentagon Papers, p. 220) A cable from
Bundy to Lodge dated October 30 expressed White House concern
and stated that" [w]e cannot accept conelusion that we have no power
to delay or discourage a coup." (Cable, Bundy to Lodge, 10/30/63)
A subsequent cable on that same day from Washington instructed
Lodge to intercede with the Generals to call off the coup if he did
not believe it would succeed. The instructions prescribed "strict noninvolvement
and somewhat less strict neutrality." (Pentagon Papers,
p.220)
Late in the morning of November 1, the first units involved in the
coup began to deploy around Saigon. The Embassy was given only
four minutes warning before the coup began. (Cable, MACV to Joint
Chiefs of Staff, 11/1/63) An aide to Don told Conein to bring all
available money to the Joint General Staff headquarters. Conein
brought 3 million piasters (approximately $42,000) to the headquarters,
which was given to Don to procure food for his troops and to pay
death benefits to those killed in the coup. (Conein, 6/20/75, p. 72)1
Conein was at the Joint General Staff headquarters during most of
the coup. (I.G.Report, C, pp. 41-42) At 'I :40 p.m., the Generals proposed
that Diem resign immediately, and guaranteed him and Nhu safe
departure. (Conein After-Action Report, p. 15) The palace was surrounded
shortly afterwards, and at 4 :30 p.m. the Generals announced
the coup on the radio and demanded the resignation of Diem and Nhu.
Diem called Lodge and inquired about the United States' position.
Lodge responded that the United States did not yet have a view, and
expressed concern for Diem's safety. (Pentagon Papers, p. 221)
According to Conein's report, Minh told Khu that if he and Diem
did not resign within five minutes, the palace would be bombed. Minh
then phoned Diem. Diem refused to talk with him and Minh ordered
the bombing of the palace. Troops moved in on the palace, but Diem
still refused to capitulate. Minh offered Diem a second chance to sur-
1 PassIng money to the coup leaders was consIdered sometime prIor to the coup. On
October 29. Lodge cabled that a request for funds should be anticipated. (Cables, Lodge to
State, 10/29/63, and 10/30/63) Coneln receIved the money on October 24, and kept It In a
safe in his house.

render half an hour later, teJJing him that if he refused he would be
"blasted off of the earth." Shortly before nightfall an air assault was
launched on the Presidential Guard's barracks. (Conein Aft~r-Action
Report, 1l/1/6:~,pp.17-18)
At 6 :20 on the morning of November 2, Diem called General Don
at the Joint General Staff headquarters and offered to surrender if he
and Nhu were ginn safe conduct to an airport. Shortly afterwards,
Diem offered to surrender unconditionally and ordered the Presidential
Guard to cease firing. According to Conein, an escort for Diem
appeared in front of the palace at 8 :00 a.m., but Diem and Nhu were
not pre~ent. (Conein After-Action Report, 11/1/63, p. ¥4)
.. Canem testIfied that he left the .TGS headquarters amIdst preparations
by the Vietnamese generals to house Diem and Nhu there under
proper security. After his return home he received a telephone call
and was told to come to the Embassy. At the Embassy he was told that
orders had come from the President of the United States to locate
Diem. He .further testified that he returned to JGS headquarters about
10 :00 a.m. and asked General Big Minh where Diem was. After some
discussion, Conein stated, Minh said that they were behind the General
Staff Headquarters, but professed that they had died by their own
hand. Minh offered to show the bodies to Conein but Conein declined
because he feared that doing so might damage United States interests.
(Conein, 6/20/75, pp. 55-57).
The details of Diem's and Nhu's deaths are not known.l There is
no available evidence to give any indication of direct or indirect involvement
of the United States.2
1 Coneln speculated that Diem and Nhu escaped through a tunnel from the palace and
fled to a Catholic Ohurch In Cholon. He opined that an informant must have identified
them and called the General Staff headquarters. (Coneln After-Action Report. 1/11/63.
p. 23) A CIA source stated that Diem and Nhu had left the palace the previous
evening with a Chinese businessman and arrived at the church at 8 :00 on the morning
of November 2. Ten minutes later they were picked up by soldiers and forced Into an army
vehicle. (Cable, Saigon to State, 11/2/63) Minh originally told Conein tbat Diem and
Nhu had committed suicide, hut Coneln doubted that Catholics would have taken their
own lives in a churcll. (Coneln, 6/20/75, p. 56) The Inspector General's Report states
that on November 16, 1963, a field-grade officer of unknown reliability gave the CIA two
photographs of the bodies of Diem and Nhu In Which it appeared their hands were tied
behind their backs. (I.G. Report, C. pp. 43-44) The source reported that Diem and Nhu had
been shot and stabbed while being conveyed to the Joint General Staff headquarters.
2 It must be noted that on October 30, 1963. Ambassador Lodge notified Washington
that there might be a request by key leaders for evacuation, and suggested saigon as a
point for evacuation. (Cable, Saigon to Washington, 10/30/63) Coneln was charl;ed
with obtaining the airplane. Between 6 :00 and 7 :00 on the morning of November 2, Minh
and Don asked Conein to procure an aircraft. Coneln relayed the request to a Station
Officer at the Embassy who replied that It would not be possible to get an aircraft for
the next twenty-four hours, since It would have to be flown from Guam. Coneln testified
that a Station representative told him that Diem could be flown only to a country that
offered him asylum and that the plane could not land In any other country. There were
no aircraft Immediately available that had sufficient range to reach a potential country
of asylum. (Coneln, 6/20/75, p. 54)
