Chapter 6 Superb acting "actor"

As for Tojo and Yamamoto's worries, in fact, even though the Nanyun Fleet was already in sight, no one in the United States believed that Pearl Harbor was in danger. Is the US intelligence agency paralyzed?of course not. After World War II, Japan was surprised to find that the then U.S. government had cracked almost all encrypted telegrams from the Japanese Ministry of Foreign Affairs.Especially in the four months before the attack on Pearl Harbor, 108 of the top-secret telegrams exchanged between the Japanese Ministry of Foreign Affairs and embassies abroad were deciphered by the United States.

Roosevelt personally ordered the implementation of the US intelligence war against Japan.Cryptanalysis experts imitated the guessing machine invented in Germany, and successfully manufactured a machine specially designed to decipher Japanese diplomatic codes, calling it "Purple" and code-named "Magic".The report written based on the deciphering results is called "magic intelligence". Roosevelt has long learned from "magic intelligence" that if the Japan-US negotiations fail to succeed, Japan will launch an attack on the United States after December 1.To this end, he held a meeting at the White House and reminded everyone: "December 1 is the most dangerous day. Japan is accustomed to surprise attacks, and it is necessary to step up research on countermeasures."

There were no troubles on December 1, but Roosevelt believed that Japan would do it sooner or later.According to the rules of war, it is always the most beneficial for the two countries to fight first, but the US public opinion at this time does not allow the government to do so.So in the end Roosevelt came to the conclusion that the first shot should not be fired, and Japan should be the first to attack. Where will Japan attack first? Through the analysis of "magic intelligence", the US government believes that Southeast Asia, including the Philippines, is the first target.Americans rely on "magic" so much that they don't know that it can sometimes create illusions in reverse and obscure their vision.

Tojo was neither stupid nor stupid. When he discovered that the United States knew his country's foreign policy well, he immediately realized that the coded telegram of the Ministry of Foreign Affairs might no longer be a secret to Americans. The Japanese government then made a rule that it is not allowed to use the Ministry of Foreign Affairs code to send highly confidential external telegrams.In this way, although Roosevelt obtained a lot of "magic information", the value of this information has been greatly reduced, and there is not even a single word about the attack on Pearl Harbor.

Yoshikawa, who served as a spy, sent a total of no less than 50 telegrams to the Naval Intelligence Bureau, of which only 3 were deciphered by the US side, and in all these telegrams, there was no word about the attack. Yamamoto was even worse. Before the war, he simply formulated a new set of combat codes for the United Fleet. Its composition was very complicated. The code used for sending messages alone had 100,000 words, and "magic" could not decipher it in a short period of time. They are all millennium-old foxes, so the level of playing "Liao Zhai" is naturally better than the other.In addition to strictly preventing the telegram from leaking, Tojo and Yamamoto racked their brains to resort to a series of blindfolds.

When the Nanyun Fleet was secretly assembled, the Tojo Cabinet sent the diplomat Saburo Kurusu as a special envoy to the United States to participate in the negotiations.Before Laiqi left, Tojo didn't tell him that the navy and army had actually started to act.This is actually done to make the trick more realistic, so that the United States can relax its vigilance. Laixi was pressed under the tank alone, and because he didn't know the truth, the performance was very down-to-earth.On the first day he came to the United States, a reporter asked him whether there would be a war between Japan and the United States, and he immediately replied confidently: "Japan will not do such a foolish thing!"

During the negotiations, Laiqi's attitude towards the United States was completely "it rains and the earth is gentle, and the young couple quarrels without holding grudges." Laixi's acting skills, which are enough to compete with an Oscar winner, made the Americans distraught.In fact, Laiqi really didn't know anything at the time, and he acted in his true colors. Afterwards, Akira Muto, director of the Military Affairs Bureau of the Japanese Army Ministry, revealed quite proudly: "When Special Envoy Kusu set off, our determination and preparations for the war were completed. The dispatch of Special Envoy Kusu was to cover up the intention of war. Now it seems that , received a great effect."

Tojo is a selected actor, while Yamamoto is also a director and starring role. Although all the telegram codes of the United Fleet have been changed, no matter what code is used, as long as the radio waves are sent out, the other party can quickly determine the location of the ship by measuring the radio position. what to do?Yamamoto made the Nanyun Fleet pretend to be dumb, and after all the radios were turned off, they only received and did not send.At the same time, he left all the radio stations and communications officers on the warships to the reserve coaching brigade, instructing the coaching brigade to frequently send out old codes, and some said a lot of them, thus concocting a large number of fake telegrams.

The Americans were really fooled. On the day the Nanyun Fleet set off, the U.S. Naval Intelligence Agency thought they were anchored in the southern inland sea of ​​Japan.Despite all his efforts, Yamamoto still determined that there was only a 50% chance of achieving the purpose of the sneak attack in this operation.In addition to factors such as bad weather and encounters with merchant ships, Yamamoto was most worried about one person—the opponent's leader Kimmel.
