First, we need to understand the context and motivation. On July 7, 1937, Japanese imperialism launched the so-called "77 Incident", known as the Lugou Bridge Incident. This incident became the fuse for Japan's full-scale war of aggression against China. However, we must note that this was not the only reason for Japan to attack China. Japan's policy of colonial expansion and military expansion in the late 19th and early 20th centuries provided the basis for its invasion of China. During this period, Japan had annexed regions such as Taiwan, Korea, and the Ryukyu Islands. However, China, as the largest country in Asia, has been an important target in Japan's expansion plans.
Japan has strong economic, military, and political ambitions for China. Economically, China, as a huge market, is a huge attraction for Japanese goods and resources. Militarily, Japan wanted to expand its territory and secure its hegemony in Asia by invading China. Politically, Japan sought to weaken China's national power through aggressive actions in order to ensure its dominance in the East Asian region. However, in order to achieve these goals, Japan needs to find an excuse. The Lugou Bridge incident became a pretext for them to launch a war of aggression against China. In fact, this incident was only a small-scale military conflict, but Japan used this as an excuse to launch a full-scale war against China. They claimed that the squadron had attacked their military base, which was a legitimate reason for them to wage a war of aggression.
However, we must see that this is just a pretext, and Japan has actually planned an act of aggression against China for a long time. They had been secretly preparing for a long time before the invasion. They mobilized a large number of troops and supplies for this purpose, and secretly set up military bases in the border areas of China. Therefore, we can say that the Lugou Bridge Incident was only the fuse of Japan's war of aggression against China, not the real cause. This all-out war of aggression against China has brought great suffering and losses to the Chinese people. The Japanese army wantonly burned, killed and looted all over China, and carried out large-scale ** against innocent civilians. In particular, the Nanjing Da** made the whole world shocked by the atrocities of Japan. It is estimated that the war killed and maimed millions of Chinese and caused serious damage to China's economic and social development.
In addition, the war also had a profound impact on world history. It made China one of the important battlefields of World War II and had a significant impact on the political landscape of the entire Asian region. At the same time, Japan's aggression also provoked strong condemnation from the international community and laid the foundation for the later Tokyo Trial.
