The purpose of national defense is to safeguard national sovereignty, unity, safeguard national security, and defend the country’s territorial integrity.

The country cannot stand without defense, and the people cannot stand without defense. As a country and a nation, the most important things are nothing more than two major events. One is a development issue and the other is a security issue.

A country’s comprehensive national strength includes: national strength, national potential, and the ability to transform potential into strength. The country makes full use of various conditions and capabilities and transforms them into national defense strength as quickly and effectively as possible. This is an important indicator of the strength of the country's comprehensive national strength.

Modern national defense still takes military struggle as its basic form. At the same time, non-military struggles such as politics, economy, science and technology, and diplomacy are becoming more and more intense, and their role is becoming increasingly important.

Types of national defense

1, expansion type. In order to safeguard their own interests around the world, major powers pursue hegemony and invade, subvert and infiltrate other countries.

2. Self-defense type. It mainly relies on its own strength and strives for extensive international support to prevent invasion by foreign enemies and maintain its own security. We will adhere to the principle of peaceful and independent defense, never expand, and will not allow other countries to invade an inch of our land.

3. Alliance type. In the form of alliances, we unite with other countries to make up for our own shortcomings. It can be divided into expansion and self-defense types, and can also be divided into unitary and multiple alliances. The former has a big country as the leader.

4. Neutral type. Small and medium-sized developed countries strictly adhere to the national defense policy of peace and neutrality, and formulate overall defense strategies and defense systems for the deployment of soldiers and civilians. Such as Switzerland.
