There are two theories about the Japanese attack on Pearl Harbor. One is that Pearl Harbor was a real attack. The second is the conspiracy of the United States to deliberately make the sneak attack successful. The first is, of course, the accepted history, and the second is circulating among some military fans, especially some Japanese who have always insisted that Pearl Harbor was a huge conspiracy. Why? Because the Japanese raid seemed to be very successful, but some inexplicable coincidences made none of the strategic intentions of the Japanese army come true.
At the beginning of World War II, the United States, as a neutral country, did not participate in the war, but made a fortune from the war. During the war, people at the time were confused about the behavior of the United States.
Pearl Harbor was one of its important military ports at the time, with at least three carrier fleets deployed. However, shortly before the Japanese attack on Pearl Harbor, the three carrier fleets at Pearl Harbor were sent to the Atlantic. At the same time, the United States stockpiled a large amount of medical supplies near Pearl Harbor and sent excellent sailors elsewhere.
Although the United States suffered heavy losses after the Japanese attack on Pearl Harbor, it did not hurt the bones of the United States, but gave the United States an excuse to join the war.
At that time, the United States was already at the forefront of the world in terms of economy, but what the United States had been worried about was that many powerful countries at that time did not recognize the political status of the United States, so the United States did not have much say in the international arena at that time, which can be seen from the fact that he was one of the victorious countries after World War I and did not get what he wanted.
The United States therefore desperately needs to gain international political standing, and war can best help it achieve it. However, the United States, as a neutral country at the time, may win this war for no reason, but it will be like a war, so there is an urgent need for an excuse to join the war, and the Japanese attack on Pearl Harbor is the best excuse.
The United States should have cracked Japan's military telegram intending to attack Pearl Harbor before, which is why the United States did so. Pearl Harbor, though attacked by Japan, did not damage the foundations of its navy and helped to demonstrate its naval might to other countries in World War II.
The United States successfully intercepted and translated the Japanese attack on Pearl Harbor.
On August 1, 1940, the United States announced an embargo on Japan, freezing Japanese bank deposits in the United States. At that time, the Japanese Ministry of Foreign Affairs intensively sent secret telegrams to all embassies and consulates in the southwest Pacific, including the Philippines, Annam, Siam (Thailand), Yangon, Malaysia, Indonesia, Singapore and other islands, ordering the destruction of codebooks at all levels except LA password. At the same time, many code words were also issued, such as "tight west wind" indicating tensions with the United States, "northern qing" indicating easing relations with the Soviet Union, "southeast rain" indicating tension in China's battlefield, "daughter wanting to return to her mother's home" indicating the withdrawal of overseas Chinese, and "east wind and rain" indicating war with the United States. There are as many as a dozen code words. It is clearly stipulated that these code words will be broadcast on the radio when necessary, and embassies are required to listen to them at all times. For a while, there was a big trend of "doing what the future is for".
Chibuzhou, who has been following Japanese intelligence, found that since May 1941, there had been a sudden increase in secret telegrams between the Japanese Ministry of Foreign Affairs and its Consulate General in Honolulu (now the capital of Hawaii, USA), which was mixed with military intelligence in addition to expatriates and businesses. He stepped up his code-breaking work to study some of the situations of the US military. He was surprised to find that the content of the Japanese code mainly included the names, numbers, equipment, berthing locations, entry and exit times, and vacation time of the officers and men of Pearl Harbor. The Foreign Ministry also repeatedly asked which day of the week there were the most ships moored, and the consul general of Honolulu called back: "After many investigations and observations, it is Sunday." This was an important basis for the Japanese attack on Pearl Harbor on Sunday, December 8.
In particular, the weather in Hawaii is frequently mentioned in the news: the area is said to have never had a storm in 30 years, and the weather is mainly sunny. On December 3, 1941, Ikebusu intercepted a special secret telegram sent by the Japanese Ministry of Foreign Affairs to The Japanese Ambassador to the United States, Nomura, asking him: First, immediately burn all kinds of secret codebooks, leaving only one ordinary codebook, and burn all confidential documents at the same time. 2. Notify the depositors concerned to transfer their deposits to the bank of a neutral country as far as possible. (3) The Imperial Government decides to take drastic action in accordance with the resolutions of the Imperial Parliament. Chi Buzhou believes that this is a precursor to the "East Wind and Rain" (Japan-Us War).
