David M Gordon-Sino-Japanese War,1931-1945-Journal of Military History 70: 1 Journal of Military History 70.1(2006)137-/ In the end, the Republic won. But China was destroyed. This war also made it possible for a successful communist revolution to destroy traditional society. By 1945, Japan was almost destroyed. Its empire failed, its political structure was reshaped by its American conquerors, and this country will finally enter a new era of peaceful economic development. The conflict has fundamentally changed these two countries. The Sino-Japanese War was the catalyst of these changes, which can be said to be the most important event in the history of East Asia in the 20th century. This article investigates a large number of documents about the war published since 1970, from its origin to its end. The war began at 1937. However, the events that led to it happened about 20 years ago. Marius Zhan Sen described how Japan and other countries divided China into spheres of influence before the end of the First World War. Unfortunately, the Japanese can't adapt to the Soviet Union's postal war and anti-imperialist policy-this was found on the Internet.
