Looking back at history, the Chinese nation suffered from wars of aggression and bullying by foreign powers. The Chinese nation is indomitable. After a long and heroic struggle, China now faces both rare opportunities for development and severe challenges. When we seize the historical opportunity and concentrate on modernization, we must clearly see that the world is still not peaceful, the national defense forces are seriously unbalanced, and hegemonism and power politics still exist and have new developments in the fields of national defense politics, economy and security. We must never let our guard down. The formulation and implementation of the national defense education law provides a reliable legal guarantee for thoroughly implementing the party's national defense education principles and policies and promoting the in-depth and lasting development of national defense education. The promulgation of the National Defense Education Law is also of great significance for improving the quality of the whole people and promoting the coordinated development of national defense construction and economic construction. At the same time, the formulation of national defense education law is also the need to implement the national defense law and education law. The general provisions of the Education Law clearly require that "the state shall educate the educated in patriotism, collectivism and socialism, and educate them in ideals, morality, discipline, legal system, national defense and national unity". Through the publicity and implementation of the national defense education law, the principle requirements of the national defense law and the education law for national defense education are embodied and implemented.

The focus of national defense education is to promote and promote the development of productive forces. Man is the decisive factor among the factors of productivity, and national defense education is the education of man. It can not only cultivate citizens' dedication to the country, but also help broaden people's thinking. By systematically learning knowledge, we can improve citizens' intelligent structure, cultivate citizens' high organizational concept and strict legal concept, minimize all kinds of illegal and criminal activities, improve the socialist spiritual civilization of the whole society, and cultivate groups of new socialist people with ideals, morality, culture and discipline.

The strength of national defense consciousness is directly related to the life and death of the country, and national defense consciousness must be realized through educational means. We should earnestly strengthen national defense education, enhance the consciousness of participating in national defense education according to law, promote the development of national defense education with practical actions, and actively contribute to national defense education in our hometown.

Through the study of military theory, I have strengthened my patriotic enthusiasm and strengthened my national defense concept. Every time I concentrate on listening, I still feel that I haven't heard enough. The teacher told us about the form and present situation of China's national defense, which enabled us to learn a lot of modern military knowledge, realize the close relationship between national defense and national security, the rise and fall of national honor and disgrace, improve our understanding of the status and role of national defense, and establish a solid concept of national defense. "Although the world is safe, it will be dangerous to forget the war" and "born in sorrow and died in happiness" ... These old sayings tell us that the more peaceful the times are, the more we must be prepared for danger in times of peace and strengthen our national defense awareness!
