The sixtieth anniversary of Hiroshima seems to be shaping up as a
subdued affair--though not for any lack of significance. A survey of
news editors in 1999 ranked the dropping of the atomic bomb on August
6, 1945, first among the top one hundred stories of the twentieth
century. And any thoughtful list of controversies in American history
would place it near the top again. It was not always so. In 1945, an
overwhelming majority of Americans regarded as a matter of course that
the United States had used atomic bombs to end the Pacific war. They
further believed that those bombs had actually ended the war and saved
countless lives. This set of beliefs is now sometimes labeled by
academic historians the "traditionalist" view. One unkindly dubbed it
the "patriotic orthodoxy."

But in the 1960s, what were previously modest and scattered challenges
of the decision to use the bombs began to crystallize into a rival
canon. The challengers were branded "revisionists," but this is inapt.
Any historian who gains possession of significant new evidence has a
duty to revise his appreciation of the relevant events. These
challengers are better termed critics.

The critics share three fundamental premises. The first is that
Japan's situation in 1945 was catastrophically hopeless. The second is
that Japan's leaders recognized that fact and were seeking to
surrender in the summer of 1945. The third is that thanks to decoded
Japanese diplomatic messages, American leaders knew that Japan was
about to surrender when they unleashed needless nuclear devastation.
The critics divide over what prompted the decision to drop the bombs
in spite of the impending surrender, with the most provocative
arguments focusing on Washington's desire to intimidate the Kremlin.
Among an important stratum of American society--and still more perhaps
abroad--the critics' interpretation displaced the traditionalist view.

These rival narratives clashed in a major battle over the exhibition
of the Enola Gay, the airplane from which the bomb was dropped on
Hiroshima, at the Smithsonian Institution in 1995. That confrontation
froze many people's understanding of the competing views. Since then,
however, a sheaf of new archival discoveries and publications has
expanded our understanding of the events of August 1945. This new
evidence requires serious revision of the terms of the debate. What is
perhaps the most interesting feature of the new findings is that they
make a case President Harry S. Truman deliberately chose not to make
publicly in defense of his decision to use the bomb.

When scholars began to examine the archival records in the 1960s, some
intuited quite correctly that the accounts of their decision-making
that Truman and members of his administration had offered in 1945 were
at least incomplete. And if Truman had refused to disclose fully his
thinking, these scholars reasoned, it must be because the real basis
for his choices would undermine or even delegitimize his decisions. It
scarcely seemed plausible to such critics--or to almost anyone
else--that there could be any legitimate reason that the U.S.
government would have concealed at the time, and would continue to
conceal, powerful evidence that supported and explained the
president's decisions.

But beginning in the 1970s, we have acquired an array of new evidence
from Japan and the United States. By far the most important single
body of this new evidence consists of secret radio intelligence
material, and what it highlights is the painful dilemma faced by
Truman and his administration. In explaining their decisions to the
public, they deliberately forfeited their best evidence. They did so
because under the stringent security restrictions guarding radio
intercepts, recipients of this intelligence up to and including the
president were barred from retaining copies of briefing documents,
from making any public reference to them whatsoever at the time or in
their memoirs, and from retaining any record of what they had seen or
what they had concluded from it. With a handful of exceptions, they
obeyed these rules, both during the war and thereafter.

Collectively, the missing information is known as The Ultra Secret of
World War II (after the title of a breakthrough book by Frederick
William Winterbotham published in 1974). Ultra was the name given to
what became a vast and enormously efficient Allied radio intelligence
organization, which secretly unveiled masses of information for senior
policymakers. Careful listening posts snatched copies of millions of
cryptograms from the air. Code breakers then extracted the true text.
The extent of the effort is staggering. By the summer of 1945, Allied
radio intelligence was breaking into a million messages a month from
the Japanese Imperial Army alone, and many thousands from the Imperial
Navy and Japanese diplomats.

All of this effort and expertise would be squandered if the raw
intercepts were not properly translated and analyzed and their
disclosures distributed to those who needed to know. This is where
Pearl Harbor played a role. In the aftermath of that disastrous
surprise attack, Secretary of War Henry Stimson recognized that the
fruits of radio intelligence were not being properly exploited. He set
Alfred McCormack, a top-drawer lawyer with experience in handling
complex cases, to the task of formulating a way to manage the
distribution of information from Ultra. The system McCormack devised
called for funneling all radio intelligence to a handful of extremely
bright individuals who would evaluate the flood of messages, correlate
them with all other sources, and then write daily summaries for
policymakers.

By mid-1942, McCormack's scheme had evolved into a daily ritual that
continued to the end of the war--and is in essence the system still in
effect today. Every day, analysts prepared three mimeographed
newsletters. Official couriers toting locked pouches delivered one
copy of each summary to a tiny list of authorized recipients around
the Washington area. (They also retrieved the previous day's
distribution, which was then destroyed except for a file copy.) Two
copies of each summary went to the White House, for the president and
his chief of staff. Other copies went to a very select group of
officers and civilian officials in the War and Navy Departments, the
British Staff Mission, and the State Department. What is almost as
interesting is the list of those not entitled to these top-level
summaries: the vice president, any cabinet official outside the select
few in the War, Navy, and State Departments, anyone in the Office of
Strategic Services or the Federal Bureau of Investigation, or anyone
in the Manhattan Project building the atomic bomb, from Major General
Leslie Groves on down.

The three daily summaries were called the "Magic" Diplomatic Summary,
the "Magic" Far East Summary, and the European Summary. ("Magic" was a
code word coined by the U.S. Army's chief signal officer, who called
his code breakers "magicians" and their product "Magic." The term
"Ultra" came from the British and has generally prevailed as the
preferred term among historians, but in 1945 "Magic" remained the
American designation for radio intelligence, particularly that
concerning the Japanese.) The "Magic" Diplomatic Summary covered
intercepts from foreign diplomats all over the world. The "Magic" Far
East Summary presented information on Japan's military, naval, and air
situation. The European Summary paralleled the Far East summary in
coverage and need not detain us. Each summary read like a
newsmagazine. There were headlines and brief articles usually
containing extended quotations from intercepts and commentary. The
commentary was critical: Since no recipient retained any back issues,
it was up to the editors to explain how each day's developments fitted
into the broader picture.

When a complete set of the "Magic" Diplomatic Summary for the war
years was first made public in 1978, the text contained a large number
of redacted (literally whited out) passages. The critics reasonably
asked whether the blanks concealed devastating revelations. Release of
a nonredacted complete set in 1995 disclosed that the redacted areas
had indeed contained a devastating revelation--but not about the use
of the atomic bombs. Instead, the redacted areas concealed the
embarrassing fact that Allied radio intelligence was reading the codes
not just of the Axis powers, but also of some 30 other governments,
including allies like France.

The diplomatic intercepts included, for example, those of neutral
diplomats or attachés stationed in Japan. Critics highlighted a few
nuggets from this trove in the 1978 releases, but with the complete
release, we learned that there were only 3 or 4 messages suggesting
the possibility of a compromise peace, while no fewer than 13 affirmed
that Japan fully intended to fight to the bitter end. Another page in
the critics' canon emphasized a squad of Japanese diplomats in Europe,
from Sweden to the Vatican, who attempted to become peace
entrepreneurs in their contacts with American officials. As the
editors of the "Magic" Diplomatic Summary correctly made clear to
American policymakers during the war, however, not a single one of
these men (save one we will address shortly) possessed actual
authority to act for the Japanese government.

An inner cabinet in Tokyo authorized Japan's only officially
sanctioned diplomatic initiative. The Japanese dubbed this inner
cabinet the Big Six because it comprised just six men: Prime Minister
Kantaro Suzuki, Foreign Minister Shigenori Togo, Army Minister
Korechika Anami, Navy Minister Mitsumasa Yonai, and the chiefs of
staff of the Imperial Army (General Yoshijiro Umezu) and Imperial Navy
(Admiral Soemu Toyoda). In complete secrecy, the Big Six agreed on an
approach to the Soviet Union in June 1945. This was not to ask the
Soviets to deliver a "We surrender" note; rather, it aimed to enlist
the Soviets as mediators to negotiate an end to the war satisfactory
to the Big Six--in other words, a peace on terms satisfactory to the
dominant militarists. Their minimal goal was not confined to
guaranteed retention of the Imperial Institution; they also insisted
on preservation of the old militaristic order in Japan, the one in
which they ruled.

The conduit for this initiative was Japan's ambassador in Moscow,
Naotake Sato. He communicated with Foreign Minister Togo--and, thanks
to code breaking, with American policymakers. Ambassador Sato emerges
in the intercepts as a devastating cross-examiner ruthlessly unmasking
for history the feebleness of the whole enterprise. Sato immediately
told Togo that the Soviets would never bestir themselves on behalf of
Japan. The foreign minister could only insist that Sato follow his
instructions. Sato demanded to know whether the government and the
military supported the overture and what its legal basis was--after
all, the official Japanese position, adopted in an Imperial Conference
in June 1945 with the emperor's sanction, was a fight to the finish.
The ambassador also demanded that Japan state concrete terms to end
the war, otherwise the effort could not be taken seriously. Togo
responded evasively that the "directing powers" and the government had
authorized the effort--he did not and could not claim that the
military in general supported it or that the fight-to-the-end policy
had been replaced. Indeed, Togo added: "Please bear particularly in
mind, however, that we are not seeking the Russians' mediation for
anything like an unconditional surrender."

This last comment triggered a fateful exchange. Critics have pointed
out correctly that both Under Secretary of State Joseph Grew (the
former U.S. ambassador to Japan and the leading expert on that nation
within the government) and Secretary of War Henry Stimson advised
Truman that a guarantee that the Imperial Institution would not be
eliminated could prove essential to obtaining Japan's surrender. The
critics further have argued that if only the United States had made
such a guarantee, Japan would have surrendered. But when Foreign
Minister Togo informed Ambassador Sato that Japan was not looking for
anything like unconditional surrender, Sato promptly wired back a
cable that the editors of the "Magic" Diplomatic Summary made clear to
American policymakers "advocate[s] unconditional surrender provided
the Imperial House is preserved." Togo's reply, quoted in the "Magic"
Diplomatic Summary of July 22, 1945, was adamant: American
policymakers could read for themselves Togo's rejection of Sato's
proposal--with not even a hint that a guarantee of the Imperial House
would be a step in the right direction. Any rational person following
this exchange would conclude that modifying the demand for
unconditional surrender to include a promise to preserve the Imperial
House would not secure Japan's surrender.

Togo's initial messages--indicating that the emperor himself endorsed
the effort to secure Soviet mediation and was prepared to send his own
special envoy--elicited immediate attention from the editors of the
"Magic" Diplomatic Summary, as well as Under Secretary of State Grew.
Because of Grew's documented advice to Truman on the importance of the
Imperial Institution, critics feature him in the role of the sage
counsel. What the intercept evidence discloses is that Grew reviewed
the Japanese effort and concurred with the U.S. Army's chief of
intelligence, Major General Clayton Bissell, that the effort most
likely represented a ploy to play on American war weariness. They
deemed the possibility that it manifested a serious effort by the
emperor to end the war "remote." Lest there be any doubt about Grew's
mindset, as late as August 7, the day after Hiroshima, Grew drafted a
memorandum with an oblique reference to radio intelligence again
affirming his view that Tokyo still was not close to peace.

Starting with the publication of excerpts from the diaries of James
Forrestal in 1951, the contents of a few of the diplomatic intercepts
were revealed, and for decades the critics focused on these. But the
release of the complete (unredacted) "Magic" Far East Summary,
supplementing the Diplomatic Summary, in the 1990s revealed that the
diplomatic messages amounted to a mere trickle by comparison with the
torrent of military intercepts. The intercepts of Japanese Imperial
Army and Navy messages disclosed without exception that Japan's armed
forces were determined to fight a final Armageddon battle in the
homeland against an Allied invasion. The Japanese called this strategy
Ketsu Go (Operation Decisive). It was founded on the premise that
American morale was brittle and could be shattered by heavy losses in
the initial invasion. American politicians would then gladly negotiate
an end to the war far more generous than unconditional surrender.
Ultra was even more alarming in what it revealed about Japanese
knowledge of American military plans. Intercepts demonstrated that the
Japanese had correctly anticipated precisely where U.S. forces
intended to land on Southern Kyushu in November 1945 (Operation
Olympic). American planning for the Kyushu assault reflected adherence
to the military rule of thumb that the attacker should outnumber the
defender at least three to one to assure success at a reasonable cost.
American estimates projected that on the date of the landings, the
Japanese would have only three of their six field divisions on all of
Kyushu in the southern target area where nine American divisions would
push ashore. The estimates allowed that the Japanese would possess
just 2,500 to 3,000 planes total throughout Japan to face Olympic.
American aerial strength would be over four times greater.

>From mid-July onwards, Ultra intercepts exposed a huge military
buildup on Kyushu. Japanese ground forces exceeded prior estimates by
a factor of four. Instead of 3 Japanese field divisions deployed in
southern Kyushu to meet the 9 U.S. divisions, there were 10 Imperial
Army divisions plus additional brigades. Japanese air forces exceeded
prior estimates by a factor of two to four. Instead of 2,500 to 3,000
Japanese aircraft, estimates varied between about 6,000 and 10,000.
One intelligence officer commented that the Japanese defenses
threatened "to grow to [the] point where we attack on a ratio of one
(1) to one (1) which is not the recipe for victory."

Concurrent with the publication of the radio intelligence material,
additional papers of the Joint Chiefs of Staff have been released in
the last decade. From these, it is clear that there was no true
consensus among the Joint Chiefs of Staff about an invasion of Japan.
The Army, led by General George C. Marshall, believed that the
critical factor in achieving American war aims was time. Thus,
Marshall and the Army advocated an invasion of the Home Islands as the
fastest way to end the war. But the long-held Navy view was that the
critical factor in achieving American war aims was casualties. The
Navy was convinced that an invasion would be far too costly to sustain
the support of the American people, and hence believed that blockade
and bombardment were the sound course.

The picture becomes even more complex than previously understood
because it emerged that the Navy chose to postpone a final showdown
over these two strategies. The commander in chief of the U.S. fleet,
Admiral Ernest King, informed his colleagues on the Joint Chiefs of
Staff in April 1945 that he did not agree that Japan should be
invaded. He concurred only that the Joint Chiefs must issue an
invasion order immediately to create that option for the fall. But
King predicted that the Joint Chiefs would revisit the issue of
whether an invasion was wise in August or September. Meanwhile, two
months of horrendous fighting ashore on Okinawa under skies filled
with kamikazes convinced the commander in chief of the Pacific Fleet,
Admiral Chester Nimitz, that he should withdraw his prior support for
at least the invasion of Kyushu. Nimitz informed King of this change
in his views in strict confidence.

In August, the Ultra revelations propelled the Army and Navy towards a
showdown over the invasion. On August 7 (the day after Hiroshima,
which no one expected to prompt a quick surrender), General Marshall
reacted to weeks of gathering gloom in the Ultra evidence by asking
General Douglas MacArthur, who was to command what promised to be the
greatest invasion in history, whether invading Kyushu in November as
planned still looked sensible. MacArthur replied, amazingly, that he
did not believe the radio intelligence! He vehemently urged the
invasion should go forward as planned. (This, incidentally, demolishes
later claims that MacArthur thought the Japanese were about to
surrender at the time of Hiroshima.) On August 9 (the day the second
bomb was dropped, on Nagasaki), King gathered the two messages in the
exchange between Marshall and MacArthur and sent them to Nimitz. King
told Nimitz to provide his views on the viability of invading Kyushu,
with a copy to MacArthur. Clearly, nothing that had transpired since
May would have altered Nimitz's view that Olympic was unwise. Ultra
now made the invasion appear foolhardy to everyone but MacArthur. But
King had not placed a deadline on Nimitz's response, and the Japanese
surrender on August 15 allowed Nimitz to avoid starting what was
certain to be one of the most tumultuous interservice battles of the
whole war.

What this evidence illuminates is that one central tenet of the
traditionalist view is wrong--but with a twist. Even with the full
ration of caution that any historian should apply anytime he ventures
comments on paths history did not take, in this instance it is now
clear that the long-held belief that Operation Olympic loomed as a
certainty is mistaken. Truman's reluctant endorsement of the Olympic
invasion at a meeting in June 1945 was based in key part on the fact
that the Joint Chiefs had presented it as their unanimous
recommendation. (King went along with Marshall at the meeting,
presumably because he deemed it premature to wage a showdown fight. He
did comment to Truman that, of course, any invasion authorized then
could be canceled later.) With the Navy's withdrawal of support, the
terrible casualties in Okinawa, and the appalling radio-intelligence
picture of the Japanese buildup on Kyushu, Olympic was not going
forward as planned and authorized--period. But this evidence also
shows that the demise of Olympic came not because it was deemed
unnecessary, but because it had become unthinkable. It is hard to
imagine anyone who could have been president at the time (a spectrum
that includes FDR, Henry Wallace, William O. Douglas, Harry Truman,
and Thomas Dewey) failing to authorize use of the atomic bombs in this
circumstance. Japanese historians uncovered another key element of the
story. After Hiroshima (August 6), Soviet entry into the war against
Japan (August 8), and Nagasaki (August 9), the emperor intervened to
break a deadlock within the government and decide that Japan must
surrender in the early hours of August 10. The Japanese Foreign
Ministry dispatched a message to the United States that day stating
that Japan would accept the Potsdam Declaration, "with the
understanding that the said declaration does not comprise any demand
which prejudices the prerogatives of His Majesty as a Sovereign
Ruler." This was not, as critics later asserted, merely a humble
request that the emperor retain a modest figurehead role. As Japanese
historians writing decades after the war emphasized, the demand that
there be no compromise of the "prerogatives of His Majesty as a
Sovereign Ruler" as a precondition for the surrender was a demand that
the United States grant the emperor veto power over occupation reforms
and continue the rule of the old order in Japan. Fortunately, Japan
specialists in the State Department immediately realized the actual
purpose of this language and briefed Secretary of State James Byrnes,
who insisted properly that this maneuver must be defeated. The
maneuver further underscores the fact that right to the very end, the
Japanese pursued twin goals: not only the preservation of the imperial
system, but also preservation of the old order in Japan that had
launched a war of aggression that killed 17 million.

This brings us to another aspect of history that now very belatedly
has entered the controversy. Several American historians led by Robert
Newman have insisted vigorously that any assessment of the end of the
Pacific war must include the horrifying consequences of each continued
day of the war for the Asian populations trapped within Japan's
conquests. Newman calculates that between a quarter million and
400,000 Asians, overwhelmingly noncombatants, were dying each month
the war continued. Newman et al. challenge whether an assessment of
Truman's decision can highlight only the deaths of noncombatant
civilians in the aggressor nation while ignoring much larger death
tolls among noncombatant civilians in the victim nations.

There are a good many more points that now extend our understanding
beyond the debates of 1995. But it is clear that all three of the
critics' central premises are wrong. The Japanese did not see their
situation as catastrophically hopeless. They were not seeking to
surrender, but pursuing a negotiated end to the war that preserved the
old order in Japan, not just a figurehead emperor. Finally, thanks to
radio intelligence, American leaders, far from knowing that peace was
at hand, understood--as one analytical piece in the "Magic" Far East
Summary stated in July 1945, after a review of both the military and
diplomatic intercepts--that "until the Japanese leaders realize that
an invasion can not be repelled, there is little likelihood that they
will accept any peace terms satisfactory to the Allies." This cannot
be improved upon as a succinct and accurate summary of the military
and diplomatic realities of the summer of 1945.

The displacement of the so-called traditionalist view within important
segments of American opinion took several decades to accomplish. It
will take a similar span of time to displace the critical orthodoxy
that arose in the 1960s and prevailed roughly through the 1980s, and
replace it with a richer appreciation for the realities of 1945. But
the clock is ticking.
