In World War II, the Axis powers, led by Germany and Japan, launched barbaric aggression against many countries, among which Japan committed unforgivable war crimes in East Asia, invaded Asian countries dominated by China, and even in the late stages of World War II, crazy Japan fought against other Allies, but the state of the war was very different. Of course, these battles all ended in the defeat of the Japanese fascists.
Taking the United States and the Soviet Union as an example, the Soviet Union sent troops to northeast China at the end of World War II, which can be described as a breaking bamboo and destroying the decay; however, the US military fought extremely hard in the Pacific theater. Logically, the Soviet Union and the United States were one of the most militarily powerful countries in the world at that time, and the economic strength of the United States was even stronger than that of the Soviet Union, but why was it so easy for the Soviet Union to fight Japan in the face of the same enemy, while the United States was very difficult to fight Japan?
First of all, we need to see the difference in the battlefield between the two countries when they encountered Japan. On May 8, 1945, Nazi Germany surrendered, and Japan was defeated. After ending the war in the European theater, the Soviet Union wanted to divide the fruits of victory in the Asian battlefield, so it decided to send troops to northeast China. There are many plains in the northeast, which are suitable for mechanical warfare, and it just so happens that the Soviet Union has always been good at armored warfare, while the Japanese army has no tanks available.
Not only that, but the plains of the northeast were well suited to the large corps operations that the Soviets excelled at. In 1939, the Japanese army once went north for oil resources, but was defeated by the Soviet Union in the Battle of Nomonhan, when the Japanese army was still strong and strong and could not defeat the Soviet Union, not to mention the end of World War II, which had long been dragged down by the war, so the Soviet army basically did not encounter any effective resistance in the northeast battlefield.
In contrast, the Pacific War between the United States and Japan, mainly at sea, and some islands, this terrain if you fight guerrilla warfare, will prolong the war indefinitely, and the Japanese army in the face of the powerful U.S. army did this, so the U.S. military is very distressed, and finally had to end the war with atomic bombs.
On the other hand, when the Soviet Union and Japan went to war, the Japanese Kwantung Army, once known as the "Flower of the Imperial Army", had transferred most of its elite troops to other battlefields, and only a small number of new recruits remained in the northeast, in addition to only a few puppet armies, and their combat effectiveness was greatly reduced. In fact, according to the development of the war, Japan's defeat was only a matter of time, but the Soviet Union believed that sending troops at the last moment of the war could get the fruits of victory and increase its influence in Northeast Asia, so this was a war without suspense.
And Japan's attack on Pearl Harbor by the US military has been a crazy gamble. The Navy was Japan's proud elite force, and the U.S. Army suffered huge losses, so the war began with an inseparable fight, and in the end it was the Battle of Midway that determined the direction of the war. Even after losing the elite troops at sea, they did not hesitate to form a crazy "kamikaze" special attack team to carry out suicide in an attempt to save the dangerous situation in the Pacific Theater, it can be said that the US military encountered considerable resistance, and the war dragged on for a very long time.
It can be said that the different performances of the Soviet Union and the United States in encountering japanese troops at that time cannot be explained simply by strength, but are related to the favorable time and place. But the only thing that can be affirmed is that the crazy and cruel fascism will be defeated, and the anti-fascist battle of the people of the world will be victorious.
