Three perspectives of national defense security?

The three perspectives of national defense security are as follows:

First, within the sovereign borderline, i.e., the sovereign frontier; second, outside the sovereign borderline, i.e., the frontier of interest; and third, non-traditional space, i.e., our advantage in national defense, which is the new frontier.

Military activities carried out by the state for the purpose of defending and resisting aggression, stopping armed subversion and secession, and defending the state's sovereignty, unity, territorial integrity, security and development interests, as well as military-related political, economic, diplomatic, scientific and technological, and educational activities.

Importance of national defense

Since the birth of any country, it is necessary to consolidate the country and strengthen its borders, and to prepare for and defend against all kinds of foreign aggression, so as to guarantee national security, safeguard national interests and promote national development.

National defense is the security guarantee for the survival and development of the country, which is related to the safety and security of the country, honor and disgrace, and the rise and fall of the country. The survival and development of the country is inseparable from the country's sovereignty and independence, territorial integrity, security, stability and unity.
