Mallary A. Silva-Grondin (2010): Nonetheless, anti-conspiracy theorist’s retaliations against conspiracy theories have not invalidated the claim of one. The evidence of prior knowledge to the attack is astonishing and believable. A few of the Pearl Harbor files became declassified in the early 1990s and provided evidence supporting the conspiracy. Only when the files become completely declassified in the future will the public know the full truth.60 Without question, Pearl Harbor was the event which lead the U.S into WWII, and there is enough evidence, although circumstantial, to illustrate the United State’s provocation of the Japanese into an act of aggression. FDR’s motives could have not only lead to the deception of the American people, but also lead the United States into WWII through the backdoor of Japan” (Mallary A. Silva-Grondin , “Conspiracy: did FDR deceive the American people in a push for war?”, Inquiries, volume 2 (1), 2010: http://www.inquiriesjournal.com/articles/136/3/conspiracy-did-fdr-deceive-the-american-people-in-a-push-for-war ).
James Perloff (2015): “On Sunday, December 7, 1941, Japan launched a sneak attack on the U.S. Pacific Fleet at Pearl Harbor, shattering the peace of a beautiful Hawaiian morning and leaving much of the fleet broken and burning. The destruction and death that the Japanese military visited upon Pearl Harbor that day — 18 naval vessels (including eight battleships) sunk or heavily damaged, 188 planes destroyed, over 2,000 servicemen killed — were exacerbated by the fact that American commanders in Hawaii were caught by surprise. But that was not the case in Washington. Comprehensive research has shown not only that Washington knew in advance of the attack, but that it deliberately withheld its foreknowledge from our commanders in Hawaii in the hope that the "surprise" attack would catapult the U.S. into World War II. Oliver Lyttleton, British Minister of Production, stated in 1944: "Japan was provoked into attacking America at Pearl Harbor. It is a travesty of history to say that America was forced into the war." Although FDR desired to directly involve the United States in the Second World War, his intentions sharply contradicted his public pronouncements. A pre-war Gallup poll showed 88 percent of Americans opposed U.S. involvement in the European war. Citizens realized that U.S. participation in World War I had not made a better world, and in a 1940 (election-year) speech, Roosevelt typically stated: "I have said this before, but I shall say it again and again and again: Your boys are not going to be sent into any foreign wars." But privately, the president planned the opposite. Roosevelt dispatched his closest advisor, Harry Hopkins, to meet British Prime Minister Winston Churchill in January 1941. Hopkins told Churchill: "The President is determined that we [the United States and England] shall win the war together. Make no mistake about it. He has sent me here to tell you that at all costs and by all means he will carry you through, no matter what happens to him — there is nothing he will not do so far as he has human power”…
The foregoing represents just a sampling of evidence that Washington knew in advance of the Pearl Harbor attack. For additional evidences, see Infamy: Pearl Harbor and Its Aftermath by Pulitzer Prize-winning historian John Toland, and Day of Deceit: The Truth about FDR and Pearl Harbor by Robert Stinnett. So certain was the data that, at a private press briefing in November 1941, General George Marshall confidently predicted that a Japanese-American war would break out during the "first ten days of December". However, none of this information was passed to our commanders in Hawaii, Kimmel and Short, with the exception of Ambassador Grew's January warning, a copy of which reached Kimmel on February 1st. To allay any concerns, Lieutenant Commander McCollum — who originated the plan to incite Japan to war — wrote Kimmel: "Naval Intelligence places no credence in these rumors. Furthermore, based on known data regarding the present disposition and deployment of Japanese naval and army forces, no move against Pearl Harbor appears imminent or planned for in the foreseeable future"…
The Roberts Commission, assigned to investigate the Japanese attack, consisted of personal cronies of Roosevelt and Marshall. The Commission fully absolved Washington and declared that America was caught off guard due to "dereliction of duty" by Kimmel and Short. The wrath of America for these two was exceeded only by its wrath for Tokyo. To this day, many believe it was negligence by the Hawaii commanders that made the Pearl Harbor disaster possible” (James Perloff, “Pearl Harbor: Hawaii was surmised; FDR was not”, New American, 7 December 2015: http://www.thenewamerican.com/culture/history/item/4740-pearl-harbor-hawaii-was-surprised-fdr-was-not ).
