Root: The corruption of modern China's social system is an important reason for the failure of the anti-aggression war. The backward political system and the serious corruption of officials make it impossible for the country to effectively organize and mobilize resources to fight against foreign invasion. In addition, the corruption of the social system has also weakened the national defense force and put the country at a disadvantage in the war. In addition, the backwardness of economy and technology in modern China was also an important reason for the failure of the anti-aggression war. China's economy is dominated by agriculture, its industrial base is weak and its technology is backward, which makes it impossible for the country to effectively provide material support and weapons and equipment in the war. At the same time, the backwardness of economy and technology also restricts the country's economic development and the improvement of comprehensive national strength, making the country at a disadvantage in the war.

Lesson: The failure of China's modern anti-aggression war shows that it is difficult for a country to resist foreign invasion if its economy and technology are backward and its social system is corrupt. Therefore, we must constantly promote the process of national modernization and enhance the country's comprehensive national strength and competitiveness.
