National defense security is the foundation of a country, and national defense is a lofty cause that every China person should be proud of. People engaged in national defense are the noblest and greatest people in the world. National defense security is a necessary condition for national political stability, a security guarantee for economic construction, a powerful backing for the independent exercise of diplomatic rights, and an important pillar for ensuring national security, honor and interests. Looking back, we can vividly see the historical scene: after the defeat of Eight-Nation Alliance, the corrupt Qing government was forced to sign an unequal treaty, although it had to reluctantly cede territory for compensation. At that time, the old China was weak and corrupt, and there was no strength to fight back. It has to trap the people in misery and injustice, and make the Chinese nation be slaughtered and bullied, and suffer the suffering that "conquered people is not as good as a SangGuQuan". This lesson is worth pondering and learning forever. It can be seen that a country cannot ensure its security, stability and territorial integrity without strong national defense security as the backing; If we don't pay attention to strengthening the construction of national defense security in peacetime, we will suffer big losses and make great disasters in wartime. War can be fought for a hundred years, and the country cannot be undefended for a day. Raise a soldier for a thousand days, and use it for a while. When the enemy enters the door and the bayonet is on his neck, it will be too late to strengthen national defense security. To this end, the Red epaulettes Action Western Command Center has launched a nationwide publicity campaign on national defense safety education for college students, aiming to make the young people in colleges and universities across the country deeply understand the importance of national defense safety and enhance their awareness of national defense safety.
