Germany 194 1 attacked the Soviet Union in World War II, and the Soviet Union was losing ground. In order to speed up the victory, Germany also invited Japan to use it to attack the Soviet Union. However, Japan was not attacked by the Soviet Union, but attacked Britain and the United States with its troops, leaving Germany and the Soviet Union to fight, but swept Southeast Asia with its troops. What's the secret behind this? Why did Japan do this? Japan's fear of the Soviet Union In fact, Japan did make a plan to go north, that is, to capture the Soviet Union. In order to verify this plan, Japan took the initiative to provoke the Soviet-Mongolian Coalition forces in Nomonhan area at 1939, thus the Battle of Nomonhan broke out. In a fierce battle, Japan suffered heavy losses, with 7,696 deaths, missing 102 1 person, 8,647 injured and 2,350 sick, with a total loss of19,000 people. Soviets also killed 9,703 people, were injured 1525 1 person, fell ill 70 1 person, and lost a total of 25,655 people. At first glance, Japan suffered little, even fewer casualties than the Soviet Union. But the Soviet Union concentrated a lot of manpower and material resources in a short time. Just comparing the shells, the Soviet Union used 3 1000 tons, and Japan used 2000 tons of materials in the whole campaign. As for technical weapons, it is even more incomparable. Japan invested no more than 100 tanks and armored vehicles, while the Soviet Union invested 524 tanks, 385 armored vehicles and artillery. It can be said that at this time, the Soviet army, tanks and armored vehicles are 7: 1, artillery is 6: 1, and the strength is 3: 1. This sharp contrast almost made Japan lose confidence, and it can be said that it basically gave up its plan to go north. Even though the quality of the Japanese Kwantung Army is higher than that of the Soviet Union at this stage, the strong national strength and industry of the Soviet Union make up for this, and the quality of personnel is unparalleled. If there is a hard fight, even the Kwantung Army will die without knowing their mother, even their emperor and the gods in heaven. However, fanatical Japanese militarists still thought there might be an opportunity, so after Nomenham, they also actively planned how to attack the Soviet Union. After the outbreak of the Soviet-German War, the number of resident divisions increased from 14 to 16, and each division increased from15,000 to 24,000. If the aviation and naval forces are counted, the total strength of the Kwantung Army at this time is 750,000, and its strength is greatly enhanced. At the same time, in view of the disadvantages of technical weapons, the Japanese Kwantung Army also strengthened technical weapons. The new artillery units include 14 field heavy artillery wing, 3 heavy artillery wings, 8 independent heavy artillery brigades, equipped with 9 tank wings, supplying 4 14 tanks, and 1025 various types of combat aircraft, with unprecedented strength. It can be said that as long as the Soviet troops in the Far East weaken their strength, the Kwantung Army will attack immediately. However, to the consternation of the Kwantung Army, the Soviet army has 30 infantry divisions, 3 cavalry divisions, 16 armored brigades and 15 artillery regiments in the Far East, with a strength of about 6 1 10,000. It has 2700 tanks and 2700 planes of various models. No matter how fierce the front line was, the Soviet Union did not mobilize the Soviet troops in the Far East, and the requirement of the Japanese base camp for attacking the Soviet Union was that it must wait until the Soviet Union's 30 or so infantry divisions in the Far East were reduced by half. That is, there are only 15 divisions. The number of tanks was reduced from 2700 to 900. When the number of aircraft is reduced from 2700 to 1000. The Japanese can attack. However, after the war, the Soviet army not only did not reduce its troops, but increased its troops, which made the Japanese Kwantung Army feel depressed. As a prerequisite for the attack, the Kwantung Army can at least occupy a small number of advantages in terms of troops, while it can minimize its disadvantages in technical weapons such as tanks, planes and heavy artillery. Only with these two basic conditions can they act. Now the Japanese Kwantung Army has no courage to attack the Soviet Union. They have been completely intimidated by the Soviet Union. The conflict between Japan and Britain and the United States Japan is an island country lacking in resources, lacking all kinds of minerals, oil and rubber at home. Although Japan occupies the northeast, its production capacity is not enough to provide Japan with much resources. The northeast, controlled by the Japanese army and Nanman Railway Co., Ltd., did not bring much profit to Japan. A typical example is Anshan Iron and Steel Plant. At that time, although the apparent profit 1 100 million yen, the steel it produced was unqualified, even the strength of ordinary steel plate was not enough, which was four times more expensive than armored steel on the market, and it was forced to sell it to enterprises in its own country, euphemistically called patriotic steel. If you don't buy it, Japanese entrepreneurs will be assassinated. The former chairman group of Mitsui chaebol was assassinated. However, this self-deception enabled the army to control the Northeast together with Nanman Railway Co., Ltd., prevented the Japanese Ministry of Finance and the Navy from setting foot in the Northeast, and benefited the leaders of the Japanese Kwantung Army. However, in practice, it can not solve the actual situation of Japan's lack of resources, that is, lack of resources. Japan relies heavily on imports for minerals, oil, rubber and other resources. Japan relies heavily on buying oil, scrap steel and rubber from the United States. After recycling, these scrap steels are the high-quality steel products that Japan needs, and the extracted waste rubber can also make up for the shortage of rubber for Japan. However, with the outbreak of the European War and the defeat of France, Japan seized the French colony in Asia. This made Britain and the United States very dissatisfied, ended most of the trade with Japan, and once put Japan in crisis. Because Japan's own oil reserves can't be used up by itself, it won't be long before Japan falls into crisis. Roosevelt directly asked Japan to withdraw from China, and terminated the scrap steel and rubber business related to Japan. Roosevelt warned Japan that if it did not withdraw its troops and went its own way, then the United States would completely interrupt its oil trade with Japan by the most drastic means and impose an oil embargo on Japan. What Britain and the United States, especially Roosevelt, did was not unreasonable. When the Japanese invaded the northeast of China, it caused dissatisfaction among countries. Because they monopolize the northeast market, goods from other countries can't be sold here, and Japan alone will make huge profits. When the war of aggression against China broke out in an all-round way, Japan completely turned the occupied area into its own property and refused American goods to enter the market, which greatly angered the United States. On the other hand, the United States is also worried about Japan's expansion in the Pacific, so it must contain Japan. As for Japan, Southeast Asia has the resources they need and has been built by countries such as Britain and the United States. As long as it captures Southeast Asia and then the Philippines, Indonesia, Australia and other places, Japan will never lack resources. In particular, the influence of Britain and the United States in the Pacific Ocean is not as good as that of Japan, which makes Japan very interested in the southward strategy. In Japan's eyes, it is more advantageous to attack Southeast Asia and expand in the Pacific than to explore the Soviet Union. Contradiction between Japan and Germany Aside from these situation problems, the contradiction between Japan and Germany is also the reason why Japan is unwilling to attack the Soviet Union. In fact, Japan has joined the axis of the Three Kingdoms. At that time, he advocated joining the army faction and advocating the strategy of going north. I believe that as long as the Soviet Union is defeated, resources will naturally not be a problem. The navy, on the other hand, opposes joining and advocates the strategy of going south After all, during the World War I between Japan and Germany, the two countries were enemies, and the distance was too far, so it was difficult to form a strategic alliance. At that time, the Japanese army and navy were at loggerheads over whether to join. The army even once surrounded the naval province. Isoroku Yamamoto, who opposed joining, once lived on a warship because the army wanted to kill him. Even when Isoroku Yamamoto is at home, he should prepare a machine gun to protect himself. At that time, Hitler's book "Mein Kampf" published by Germany in Japan deleted the eleventh chapter of the original German. One paragraph reads: "Japan is an unimaginative inferior nation, but Germany can use Japan, and their talents and perseverance can serve Germany." "In other words, Hitler looked down on Japan, and he would conquer Japan in the future. The hillbilly of the army basically can't understand the German version of Mein Kampf, but the navy knows it, so it opposes it and advocates the strategy of going south. In fact, when the Battle of Nomenheim broke out in May 1939, Japan originally planned to attack the Soviet Union together with Germany in order to win the war against the Soviet Union and realize the plan of moving northward. However, on August 23rd, Germany and the Soviet Union concluded the Soviet-German Non-aggression Treaty, which made Japan betrayed by its allies. This made Japan very depressed and had to sign an armistice agreement with the Soviet Union to admit its defeat in Nomenham. Although Japan later joined the axis of the Three Kingdoms, the army's northward strategy had basically gone bankrupt, and the navy gained the upper hand, and finally the navy's southward plan was implemented. On the other hand, Japan is also worried that if it defeats the Soviet Union, Germany will March directly into Asia. It is not in Japan's interest to have such a powerful country as a neighbor. If Germany goes deep into China to get more resources, then the Japanese army can't resist the Germans. In the end, I'm afraid it's a dead rabbit and a dead dog. Therefore, Japan would rather attack Britain and the United States than unite Germany to attack the Soviet Union. After all, Japan does not want Germany to become their new strong enemy after defeating the Soviet Union. Conclusion In fact, Japan was unwilling and unwilling to help Germany defeat the Soviet Union from the beginning, which did them no good or even great danger. Axis itself is an alliance with different intentions. How can we expect them to really unite? So it's normal for Japan not to soviet strike, because Germany and Japan don't really regard each other as allies, but only use each other.
