In 1941, the German army encountered great difficulties in the Soviet-German battlefield, millions of German casualties in the Soviet-German battlefield, at this time, Hitler was anxious like ants on a hot pot. Several times I asked Japan to send troops north as soon as possible, but why did Japan not take action?
There are several main reasons for this, the first of which was that the Kwantung Army deployed 700,000 Japanese troops to the northeast in 1942. By this time, Japan had discovered that the Germans could no longer win quickly in the Soviet-German battlefield. At the time, Japan's Showa Emperor said Stalin was more resilient than he thought.
After the mobilization of the Kwantung Army was completed, japan found that there was no cheap to take. Secondly, Japan found that the total number of Soviet troops in the Far East did not decrease, but continued to increase. The Soviets' approach was to send old troops to Europe and then send the newly formed troops to the Far East.
At the outbreak of the Soviet-German War in June 1941, the Soviet army in the Far East was 700,000 men, with 3,188 tanks and 4,140 warplanes. By July 1942, the Soviet army in the Far East had grown to 1.44 million. The Soviet Army in the Far East was twice as numerous as the Kwantung Army.
It is 6 times the number of the Kwantung Army on tanks and 7 times the number of the Kwantung Army on warplanes. Moreover, the Soviet army in the Far East has completed the system of large-depth permanent fortifications, and if it wants to attack such a large-area fortress area with a depth of hundreds of kilometers, it must take at least 5 times the strength and weapons to complete it.
In this case, if the Kwantung Army wanted to launch an attack, it must have 50 times the combat effectiveness of the Soviet Army to succeed. According to the Analysis of the Japanese themselves from the Battles of Zhanggufeng and Nomonkan, the combat effectiveness of a complete division of the Soviet Army was 75% of that of a three-unit division of the Japanese army.
Then according to the maximum extent, the 14 divisions of the Kwantung Army are equal to 20 Soviet divisions at most, and if it is a state of attack, it is still a large-depth and permanent fortification, and it can only attack no more than 10 Soviet divisions at most. But the Soviets had 1.44 million men.
In August 1941, as the Japanese army was strengthening its Kwantung Army in tohoku, the United States announced an oil embargo on Japan. At that time, no oil field was found in Siberia, the oil field in Siberia was found in the 60s, and the development of oil field was in the 70s. At this time, Japan was determined to go to war against Britain and the United States, because Japan only had 24 months of oil reserves, and once it did not go to the South China Sea to seize the oil fields, Japan could only wait for the surrender.
