Before the July 7 Incident, there were many reasons why Chiang Kai-shek did not resist Japan. First of all, the influence of the domestic political environment is one of the important reasons. At that time, China was full of internal contradictions, warlords were divided, the people were struggling to make a living, and the country was facing a turbulent situation. Chiang Kai-shek needed to concentrate his efforts on destroying the Communist Party and other reactionary forces and maintaining the unity and stability of the country.
Second, the international situation also had a profound impact on China's War of Resistance Against Japanese Aggression. The continuous expansion of Japanese imperialism in China's periphery posed a serious threat to China. However, due to factors such as weak national strength, failed diplomatic mediation, and the appeasement policy of the international community, Chiang Kai-shek was unable to take decisive measures to resist Japanese aggression.
In addition, Chiang Kai-shek's personal decisions were also one of the important factors influencing his anti-Japanese attitude. He has repeatedly emphasized the idea that "if you want to fight abroad, you must first settle the interior", believing that only on the basis of solving domestic problems can we resist the war of war abroad. This thinking reflected the mentality of Chinese society at the time to a certain extent, but it also limited his ability to act in the face of external threats.
To sum up, before the July 7 Incident, there were many reasons why Chiang Kai-shek did not resist Japan in time. These include the constraints of the domestic political environment, the impact of the international situation, and the factors of individual decision-making. The combination of these factors made it impossible for Chiang Kai-shek to win support and assistance internationally, and it was difficult for him to rally the strength of the whole people to resist the war at home. Therefore, in the later War of Resistance Against Japan, the Chinese people went through arduous struggles and sacrifices before finally achieving victory.
