National defense education for all is a fundamental project for building and consolidating national defense and a strong people's army. It is an important component of the Party's propaganda and ideological work, and an effective way to promote patriotism and enhance the national defense awareness of the whole people. The 20th National Congress of the Communist Party of China focused on consolidating and improving the integrated national strategic system and capabilities, and made an important deployment of "deepening national defense education for all", fully demonstrating the historical initiative of our party to carry forward excellent traditions, continuously consolidate and develop military, government, military, and civilian unity in the new era and new journey, and create a new situation of national defense and military modernization. Fully understand the significant significance of strengthening and improving national defense education for all in the new era, consolidate ideological consensus, and enhance awareness of actions. The world is experiencing unprecedented changes in a century, and China is facing a complex and ever-changing security and development environment. Traditional and non-traditional security threats are intertwined. Faced with new situations and tasks, the Party and the people have higher expectations for building and consolidating national defense and building a strong people's army, and have higher requirements for deepening national defense education for all. Emphasizing national defense education is a valuable historical experience and excellent tradition of the Chinese nation. The country cannot stand up without defense, and the people are uneasy without defense. Emphasizing national defense education is an important guarantee for the continuous growth and development of the Chinese nation, reflecting the historical wisdom of the Chinese nation. At the beginning of Sun Tzu's Art of War, "Dao" is listed as the top of the "Five Things", which means "Dao is the one that makes the people and the people agree." This means that the political foundation of military strategy is the unity and virtue of the people and the country, which is the key to determining victory in war. For thousands of years, the Chinese nation has formed and developed traditional military ideas such as "being vigilant in times of peace", "integrating troops into agriculture", "enriching the country and strengthening the military", and "patriotic education and warfare". National defense education has permeated all aspects of traditional society. It is under the guidance of the ideology of emphasizing military preparedness and education that the Chinese land has eliminated the war disasters caused by multiple foreign invasions, providing basic living conditions for the reproduction and survival of the Chinese nation. Emphasizing national defense education is a strategic move to address the unprecedented changes in the world in a century. The sharper the struggle, the more necessary it is to develop people's war strategies and tactics, and build a strong system of strategic deterrence. Only when the whole society has a solid concept of national defense and maintains a strong ability to mobilize national defense, can we effectively defend national sovereignty, security, and development interests. Emphasizing national defense education is the essence of preparing for military struggle. In today's world, hegemonism is still rampant, peace and development are facing challenges, and the factors leading to war are far from being eliminated. The Chinese nation is a peace loving nation, and China has always been a steadfast force in maintaining world peace. However, we cannot relax and be prepared for military struggle for a moment.
