The war of aggression against China is a historical accident and a historical necessity.

At that time, due to the Meiji Restoration, Japan's productivity was unprecedentedly strong and developed into a developed country at the forefront of the world. In addition, Japan is a narrow island country, lacking resources and crisis awareness. With the deepening of domestic contradictions, in order to divert the attention of domestic contradictions, the Japanese ruling class launched a war of aggression, which not only diverted the explosive contradictions between the domestic bourgeoisie and the proletariat, but also plundered the original means of production necessary for Japan's development through the war of aggression. Therefore, shifting domestic class contradictions and meeting the needs of the original means of production necessary for Japan's development are the fundamental reasons for launching the war of aggression.
