If the national defense is weak, it is impossible to resist foreign aggression, defend national sovereignty, territorial integrity and security, let alone safeguard the country's overseas public rights and interests and stand among the nations of the world. Without a strong national defense, national security can not be guaranteed, economic construction can not be carried out normally, and political stability, people living and working in peace and contentment, national prosperity and long-term stability can not be discussed.
There are many levels of goals to expand information-based modern national defense.
The lowest goal is self-defense, and the scope of national defense is limited to national territory and territorial sea, with a view to safeguarding national sovereignty and territorial integrity.
The intermediate goal is a regional goal, limited to the limited surrounding areas outside the national territory, focusing on increasing the depth and flexibility of national defense and creating a more relaxed surrounding environment for national security and development.
The highest level goal is the global goal, and national defense covers the whole world, focusing on protecting the country's interests in the world.
