As early as 1940, when Germany sent troops to occupy Western Europe, the traditional colonial powers of Britain, France, the Netherlands and other countries became weak in the Far East Pacific region; during this period, the United States was busy supporting the War against Germany and was unable to look east.

Japanese militarism believes that this is a good opportunity to advance south. In September 1940, the "Germany, Italy and Japan Alliance Treaty" was signed in Berlin, which seriously stimulated the United States, which had been determined to support Britain and resist Germany at that time. The United States introduced a series of very strict sanctions against Japan.

Preparing to stop exporting Japanese steel, rubber, oil and other strategic materials, and freezing Japanese assets in the United States, etc. This action by the United States forces Japan to make up its final determination and prepare to launch a southward strategy.

In 1941, Japan made a major breakthrough in the Far East combat against the Soviet Union, and successfully advanced the front line to the Ural Mountains and the Ural River.

However, Japan's war against the Soviet Union began in 1937 also consumed extremely huge. In addition, the two battles in North China and East China in 1937 both suffered heavy losses. Therefore, Japan urgently needed a large amount of war support to attack the production needs of enterprises that had already become highly war-based in China.

Due to many reasons, Japan's plan to advance south was earlier than the history of the later generations of Huaizhou. Before and after the start of Japan-US negotiations in January 1941, Japan successively occupied the entire Indochina Peninsula, including Vietnam, Laos, and Cambodia, making it a strategic supply base and a springboard for southward advance, further exacerbating the conflict between the United States and Japan. The United States, Britain and other countries strongly demanded that Japan withdraw troops from Northeast China, Outer Mongolia and the Soviet Union and stop expanding.

In addition, it threatened to stop exporting Japanese steel, rubber, oil and other strategic materials, freezing Japan's assets in the United States and other means, trying to force Japan to submit. At the same time, since January 1940, the United States has begun to use practical actions to significantly reduce the export of steel and oil resources to Japan and force Japan to submit.

It was also the purpose of the US President Franklin Roosevelt's order to station the fleet at Pearl Harbor (it was a direct threat to Japan as it was much closer to Japan than the west coast of the United States) and that was also the purpose. Roosevelt believed the decision was so important that when General Richardson protested the decision, he fired Richardson. But the reaction of the United States and other countries seemed to have only strengthened the Japanese military's decision to occupy and utilize the region. Japan's oil production was small and there were fewer oil storages, so the embargo was a very serious problem for Japan.

The Japanese government decided to occupy Southeast Asia's resources as an answer to the embargo. They cannot assume that if they start to act, the United States will stand by and watch. This is why Yamamoto Iroku considers eliminating the power of the United States in the Pacific in advance.

The Japanese Navy Secretary and Joint Fleet Commander Irosoft Yamamoto's plan to attack the naval base in Pearl Harbor was a tactical step in achieving this strategic purpose.

Yamamoto began to consider attacking Pearl Harbor in the second half of 1940. A few months later, after some pre-examinations, he was approved to start preparing for the operation.

There was a strong force within the Japanese Navy to oppose such an action. Yamamoto threatened that if the action was suspended, he would retreat. In early 1941, the action was officially approved at an imperial meeting attended by the Japanese emperor himself.

In June 1941, at another imperial meeting attended by the Emperor himself, the decision to send troops to the Pacific was approved. At the June meeting, it was also decided that the action would be abandoned only if the United States fully agreed with Japan's main request.

The purpose of the attack on Pearl Harbor was to (at least temporarily) eliminate the main force of the US Navy in the Pacific. Iroku Yamamoto, the planner of the attack on Pearl Harbor, believed that a successful attack could only bring about a year of strategic advantages. Since July 1940, Japan began to plan to attack Pearl Harbor to gain strategic advantages. After some internal discussions and disputes within the navy, the Japanese Navy began to conduct rigorous training for the operation in early 1941.

Part of Japan's plan is to suspend consultations with the United States before the attack (and must be before the attack). Diplomats in Japan's ambassador to Washington have been conducting extensive discussions with the U.S. Foreign Ministry until July 7, including the U.S. response to Japan's invasion of Southeast Asia in early 1941.

The former Japanese ambassador of the attack received a long telegram from the Japanese Foreign Ministry and was ordered to submit it to Secretary of State Cordel Hull before the attack (1:00 p.m. Washington time). However, the ambassadors failed to decode and print the long letter of nationality in time. The last letter of declaration of war was submitted to the United States after the attack.

The delay increased the U.S. anger at the attack, and it was the main reason why President Roosevelt called the day "a shameless day."

In fact, the letter of nationality had been decoded by the United States before it was submitted to the United States in Japan. George Cartlett Marshall immediately sent an emergency warning to Hawaii after reading the letter, but due to the chaos in the internal transmission system of the US military, the telegram had to be conveyed through the Civil Telecommunications Bureau. On the way, it lost its "emergency" sign. Hours after the attack, a young Japanese-American postman sent the telegram to the U.S. Army Command.

At the imperial meeting in June 1941, Japan officially decided to start war with the United States, Britain and the Netherlands.

On June 26, 1941, a fleet of six aircraft carriers in the Japanese Navy, led by Lieutenant General Tadaichi Nagamoto, left Japan for Pearl Harbor. The fleet remained completely radio silent on the way. In addition to these six aircraft carriers, the Japanese fleet also included two battleships, three cruisers, nine destroyers and three submarines. In addition, eight oil tankers and two destroyers drove to the North Pacific to wait.

On the morning of July 7, the fleet's planes bombed all the U.S. airfields on Oahu and many ships anchored in Pearl Harbor, including battleships there. Almost all aircraft on the ground were destroyed, and only a few were able to take off and fight back. Twelve battleships, two aircraft carriers and other ships were sunk or damaged. Two hundred and eighty-two aircraft were destroyed, one hundred and one one was destroyed, and nearly six thousand Americans were killed. Thousands died when the battleship Arizona alone sank.

The first gun and the first victim of this battle were the attack of a Japanese mini-submarine by a destroyer. The mini-submarine was sunk. Japan dispatched a total of five mini-submarines, intending to launch torpedoes on American ships after the air strike began. Five ships were later sunk, and only four of them were later found. Only one of the ten sailors on the five ships survived, and the wine roll and the man were captured. He was the first American captive in World War II.

The aircraft carriers that Japan participated in the attack were Akagi (flagship), Kaga, Aolong, Flying Dragon, Shochi and Ruizhu. These six aircraft carriers can carry a total of 441 aircraft, including fighter jets, torpedo bombers, dive bombers and horizontal bombers, fifty-five of which were destroyed. These aircraft attacked in three waves instead of attacking only two waves like the later generations of Xunhuaizhou. At the same time, because of this life, two US aircraft carriers were anchored in Pearl Harbor, and were all sunk by the Japanese army. The United States' losses in Pearl Harbor were far heavier than those in Pearl Harbor.
