Description:

In Day of Deceit, Robert Stinnett delivers the definitive final chapter on America's greatest secret and our worst military disaster. Drawing on twenty years of research and access to scores of previously classified documents, Stinnett proves that Pearl Harbor was not an accident, a mere failure of American intelligence, or a brilliant Japanese military coup. By showing that ample warning of the attack was on FDR's desk and, furthermore, that a plan to push Japan into war was initiated at the highest levels of the U.S. government, he ends up profoundly altering our understanding of one of the most significant events in American history.

Review

On the night of December 8, 1941, Edward R. Murrow left the White House after a midnight meeting with Franklin Roosevelt and told his wife, "It's the biggest story of my life, but I don't know if it's my duty to tell it or forget it." Murrow never did tell it. Robert Stinnett spent seventeen years trying, and Day of Deceit is the result — a book that makes an explosive, meticulously documented argument that Pearl Harbor was not a failure of American intelligence but a success of presidential strategy. What Stinnett has assembled is not merely another entry in the long tradition of Pearl Harbor revisionism; it is the most archivally substantive brief for the prosecution that the "foreknowledge" thesis has ever received, and it demands to be reckoned with even where it overreaches.

The book's central claim is that FDR, constrained by an American public that was 88 percent opposed to entering the European war, approved a deliberate program of provocations designed to force Japan into committing "the first overt act." The documentary linchpin is Lieutenant Commander Arthur H. McCollum's eight-action memo of October 7, 1940, reproduced in full in Appendix A. McCollum, head of the Office of Naval Intelligence's Far East desk, proposed an interlocking series of provocations — arranging British base access in the Pacific, denying Japan Dutch East Indies oil, retaining the U.S. fleet at Pearl Harbor, instituting a full trade embargo, and running "pop-up" cruiser incursions into Japanese home waters, among others. His reasoning was stark: "It is not believed that in the present state of political opinion the United States government is capable of declaring war against Japan without more ado." Captain Dudley Knox endorsed the memo with "I concur in your courses of action." Stinnett presents evidence that FDR approved it the following day — October 8, 1940 — the same day he clashed with and ultimately fired Admiral James O. Richardson for opposing the fleet's retention at Pearl Harbor. The eight actions were implemented systematically over the next fourteen months. By the time Admiral Harold Stark sent his revised war warning on November 28, 1941, the instruction to Pacific commanders was explicit: "IF HOSTILITIES CANNOT REPEAT CANNOT BE AVOIDED THE UNITED STATES DESIRES THAT JAPAN COMMIT THE FIRST OVERT ACT." The directive, Stinnett argues, came from Roosevelt himself.

What distinguishes Day of Deceit from earlier works in this tradition — John Toland's Infamy, for instance, or the various congressional dissents — is the depth of Stinnett's archival excavation. Through Freedom of Information Act requests spanning more than a decade, he pried loose Navy routing slips, intercept station logs, and the internal communications of a signals-intelligence apparatus that was, by any measure, extraordinary. The book maps a 22-station Pacific network — Stations US, HYPO, H, CAST, SAIL, FIVE, KING, BAKER, ITEM, plus British and Dutch counterparts — that Stinnett calls "the splendid arrangement." This network was, he demonstrates, reading Japanese diplomatic and naval traffic at a depth that earlier histories either minimized or denied. The Purple diplomatic code had been broken by William Friedman's Army Signal Intelligence Service by September 1940. Agnes Meyer Driscoll's civilian Navy team solved the Japanese 5-Num naval operations code — the principal Imperial Navy cipher, designated JN-25 by American cryptographers — the same fall. Rear Admiral Royal Ingersoll's October 4, 1940 letter to Admirals Richardson and Thomas Hart acknowledged the system was "99 percent readable." By the following spring, Purple machines had been delivered to Churchill at Bletchley Park and to Station CAST on Corregidor.

Stinnett's reconstruction of what American intelligence knew in the weeks before December 7 is the book's strongest contribution and the section where his methodology is most persuasive. He compiles 129 Japanese naval intercepts between November 15 and December 6, 1941 — 60 from Vice Admiral Chuichi Nagumo, 24 from Tokyo to the First Air Fleet, 20 from the carriers themselves — that directly contradict the postwar claim, maintained by Pacific Fleet intelligence officer Edwin Layton and others, that the Japanese task force maintained "super radio silence." The evidence includes a November 18 plain-language dispatch naming "HITOKAPPU BAY" as the anchorage; Admiral Isoroku Yamamoto's thirteen dispatches from Hitokappu Bay; and, most dramatically, the "CLIMB MOUNT NIITAKA 1208" war-start order, intercepted at Station H in Heeia, Hawaii by radioman Joseph Christie Howard on December 2 — five days before the attack. Howard, who outlived Layton by fifteen years, contradicted Layton's multiple accounts of whether the message was ever received. Stinnett further documents the so-called "bomb plot" messages: Foreign Minister Shigenori Togo's September 24, 1941 instruction to Japanese spy Tadashi Morimura requesting a grid of Pearl Harbor berthing positions, and Morimura's reply identifying Battleship Row by the code designation "FG." On December 6, Morimura sent his final PA-coded message: "THERE ARE NO BARRAGE BALLOONS UP AND THERE IS AN OPPORTUNITY LEFT FOR A SURPRISE ATTACK AGAINST THESE PLACES." It was intercepted but, Stinnett argues, never forwarded to Admiral Husband Kimmel or General Walter Short.

The climactic sequence is devastating. On the evening of December 6, Lieutenant Francis Brotherhood at Station SAIL decoded Togo's instruction that Ambassador Kichisaburo Nomura deliver Japan's 14-part ultimatum "AT 1:00 P.M. ON THE 7TH YOUR TIME" — which was 7:30 a.m. in Hawaii. FDR read the memorandum at 9:45 p.m. and told his naval aide, Lieutenant Lester Schulz, "This means war." General George Marshall did not send his warning to Hawaii until late morning on December 7, transmitting it by Western Union and RCA commercial cable rather than the Navy scrambler telephone — a fifteen-hour delay that the Army Pearl Harbor Board later concluded constituted a failure of command. Meanwhile, the Navy had cleared the North Pacific of merchant shipping, rerouting vessels through the Torres Strait in what Stinnett calls the "Vacant Sea" order, designed to give Nagumo's carrier force an unobstructed approach. Rear Admiral Richmond Kelly Turner later admitted it bluntly: "We sent the traffic down via Torres Strait, so that the track of the Japanese task force would be clear of any traffic." At 6:45 a.m. on December 7, the destroyer USS Ward sank a Japanese midget submarine outside the harbor's entrance — the first overt act had already occurred. Thirty-seven minutes later, the attack began.

Stinnett is at his best as an investigative journalist excavating the institutional mechanics of the post-attack cover-up. The narrative of concealment begins on December 11, 1941, when Rear Admiral Leigh Noyes issued his directive to subordinates: "Destroy all notes or anything in writing." It hardened into permanent policy under Fleet Admiral Ernest King, who classified the very existence of the 165-member "On The Roof Gang" of Navy cryptographers as TOP SECRET, threatening imprisonment and loss of veterans' benefits to anyone who disclosed the codebreaking successes. None of these 165 personnel ever testified before any of the nine successive Pearl Harbor investigations. The 39 volumes of the 1945-46 Joint Congressional Investigation constituted, in Stinnett's view, "a total sham" — the crucial Japanese military intercepts, housed in the Station US Papers at the National Archives, were never shown to Congress. When Senator Homer Ferguson requested access to the 5-Num intercepts, the "Winds Code" controversy — an apparent red herring about a weather-report code — was fed to the press, derailing the inquiry. Sixty-five COMSUMs (Communication Summaries) had their radio-direction-finder pages physically cut out before being presented to the 1945 hearings. The pattern holds through to 1995, when the Pentagon's Dorn investigation failed to call surviving intercept operators Homer Kisner, who had written a suppressed war-warning report on December 6, 1941, or Duane Whitlock, who could testify to Station CAST's codebreaking achievements.

The May 2000 FOIA release that Stinnett documents in the paperback Afterword confirmed, at least, that Station CAST had solved the Japanese naval operations code by November 16, 1941 — three weeks before the attack. This alone vindicates a central pillar of his argument and exposes the postwar denials as false. The 4,000-plus communications intelligence documents released included Admiral Osami Nagano's November 5 radio messages setting the first week of December for the war's start. Stinnett's finding that 151 Navy routing slips trace intelligence delivery from McCollum's "F-2" desk directly to Roosevelt from February 1940 onward is a piece of archival detective work that future historians cannot ignore, whatever they make of his conclusions.

Yet the book's strength — its prosecutorial focus — is also its vulnerability. Stinnett builds a powerful case that American intelligence could have warned Pearl Harbor and that Washington did pursue a strategy of provocation. It is a further step to argue that the two facts are causally connected — that the intelligence was deliberately withheld in order to achieve the provocation. Here the evidence becomes circumstantial, and Stinnett's treatment of it sometimes shades from the forensic into the tendentious. The "first overt act" strategy is well-documented, but strategic provocations and a willingness to sacrifice 2,476 American lives are categories of different moral magnitude. The book does not quite bridge the gap between McCollum's memo and the claim that FDR knowingly allowed the fleet to be destroyed. Stinnett concedes that his case is interpretive, but the momentum of his narrative often treats inference as established fact. The mutilated COMSUMs are suspicious; they are not, in themselves, a smoking gun. The radio-direction-finder bearings that Robert Ogg plotted in San Francisco's Twelfth Naval District, showing Japanese warships in the North Pacific, are suggestive but technically contested. The missing Yamamoto SMS messages numbered 607-619 — held back by the NSA from the 1979 Carter administration release — remain a lacuna that can sustain multiple interpretations.

The treatment of certain figures also raises questions. Joseph Rochefort, the Station HYPO commander, is presented as complicit in the cover-up, his postwar remark that the attack was "a pretty cheap price to pay for unifying the country" offered as Exhibit A. But Rochefort was the officer most responsible for the intelligence triumph at Midway six months later, and reading his entire career through the lens of Pearl Harbor may flatten a complicated man. Edwin Layton's multiple contradictory accounts of the NIITAKA message are genuinely damaging to his credibility, but Stinnett's relentless pursuit of him reads at times like personal animus. The book's framing of the Japanese-American community in Hawaii — citing FDR's 1936 secret memorandum calling for concentration camp lists and noting that dual citizen Richard Kotoshirodo was interned at Topaz — opens a racial dimension to the surveillance state that the book acknowledges but does not fully explore. The apparatus Stinnett documents was not merely reading Japanese naval traffic; it was wiretapping the Japanese consulate, surveilling Japanese nationals through the FBI and ONI, and routing commercial RCA cable traffic to Navy intelligence. This was ethnic surveillance at scale, and Stinnett, focused on the operational story, does not pause to examine what it meant for the democratic norms the war was ostensibly fought to defend.

Day of Deceit sits at the intersection of investigative journalism and revisionist historiography, and it is stronger in the first register than the second. As a piece of archival journalism, it is a triumph — a demonstration that the American security state did not suddenly learn to keep secrets after 1945; it was already expert at it by 1941. The book's contribution to the long Pearl Harbor controversy lies less in its verdict than in its evidence. It forces any serious reader to concede that the standard narrative — a sleeping giant caught off guard by a perfidious enemy — cannot survive contact with the intercept logs Stinnett has published. The question is no longer whether Washington knew an attack was coming, but exactly what it knew, when it knew it, and what it did with the knowledge. That the answer remains contested after six decades of classification and nine investigations is itself the most damning evidence Stinnett presents.

The book will not convince readers who demand a signed confession from FDR, and it may alienate those who find its argument too sweeping. But for anyone willing to follow the documentary trail — the bomb-plot grids, the "all clear" messages, the routing slips, the mutilated COMSUMs, the gags on the 165 cryptographers who took their secrets to the grave — Day of Deceit makes the official version difficult to sustain. Stinnett's own prediction, that the facts he uncovered would be argued over "for many years by people of good faith and from all political persuasions," is the right measure of his accomplishment. He did not settle the argument. He made it impossible to have honestly without his evidence in hand. That is what investigative journalism at its best does, and it is enough.
