The decline of the Kuomintang can be mainly analyzed from the following aspects: First, the limitations of the Kuomintang's own class are opposed to the people, especially the peasants who account for the vast majority of China's population, making the people miserable. Who will help him? Second, corruption within the Kuomintang, including corruption in the army. As we all know, from the founding of the Republic of China to the nominal victory of the Chiang Kai-shek government in the war of reunification and liberation, the Kuomintang was always composed of several factions, and various forces competed with each other for favor and intrigued with each other. The fundamental purpose was to preserve their strength, and it was impossible to implement the superior's operational plan well. Third, Chiang Kai-shek's own personal defects, as we know, Chiang Kai-shek is a very successful politician, but he is not a great strategist, and he made a mistake that many leaders will make: he has no command and has numerous part-time jobs all his life. Causing confusion in the command system; Fourth, the paralysis of the Kuomintang's secret service system, although the Kuomintang has two major secret service agencies, centralized and military, is frightening. But more often, they just pointed their guns at the people and at Chiang Kai-shek's dissidents. For the * * * production party, they have completely lost their left and right wings, so that not only do they know nothing about the enemy's movements, but even their own battle plans are always exposed to the enemy, thus completely losing the initiative on the battlefield. In this case, even if the United States has millions of soldiers and sophisticated machinery and equipment, it is only escorting the * * * production party. From the above four points, we can see that the Kuomintang is doomed to fail in Chinese mainland, and its failure is due to its own reasons, only a matter of time.
