What is the historical course of China's national defense?

I. The Kaiser's March in the Early Period of Liberation

The first period of New China's national defense construction was the Kaiser's March from 1949 to 1964. If the country's economic construction ended its first golden period of development in 1958 and fell into the wrong zone, the guidance of national defense construction at the end of the 1950s was still rare to maintain a relatively sober understanding of the situation, until 1964 was still able to move forward on a healthy path.

Second, the difficult development in the twists and turns and turmoil

The construction of socialism with Chinese characteristics is an unprecedented undertaking, and it is inevitable that it will go through twists and turns, and so is the development of national defense. Since the mid-1960s, there has been continuous political turmoil in China, and the development of China's national defense has also seen a "saddle shape".

Three, in the reform and opening up ushered in the great development

China's achievements in modernization of national defense, through the window of the National Day parade in Tiananmen Square, also to the domestic and foreign full display. For example, most of the equipment unveiled in the parade for the 35th anniversary of the National Day in 1984 lagged behind the world's advanced level by more than a generation, and in the Tiananmen Square parade for the 50th anniversary of the National Day in 1999, the unveiling of new tanks, armored vehicles and various types of missiles has narrowed the gap between the international advanced level and the gap has narrowed considerably.

Defense accompanies the emergence of the state and serves the national interest. Churchill famously said, "We have no eternal friends or eternal enemies, only eternal interests." The national defense in this speech is directly related to the security of the country, the dignity of the nation and the development of society.

From the supreme head of state to every citizen, from military to political, economic, cultural, educational, scientific and technological and ideological are closely related to it. Modern national defense is centered on military forces and also includes related non-military forces; it attaches importance to the country's war potential, especially the efficiency of mobilization in wartime; it is also a competition for comprehensive national power mainly based on economy and science and technology.

The modern army is a knowledge- and technology-intensive armed group, emphasizing the quality of the army over the "sea of men". The role of national defense in peacetime is deterrence, the requirement of victory without war; wartime defense is the responsibility of the actual combat, the goal is to win.
