China's peripheral security is still relatively severe. In East Asia, the United States, Japan, the United States and South Korea have joined forces to build military bases, with a very clear purpose, that is, to use Japan's hatred of history, the rising momentum of militarism, the desire to covet China's superior rich resources and the psychology of South Korea's seeking national affirmation to form a powerful military encirclement in the land territory of northeast China and the eastern waters. Perhaps, in the future, this military group will use the North Korean nuclear issue as an excuse to create an unfavorable situation for our country on land and at sea. Moreover, Taiwan Province and Diaoyu Island can explode at any time, and because these two regions have natural strategic advantages and are closely related to their interests, in the event of a violent conflict, it is bound that the United States and Japan will be involved in the war at all costs, in which case China will be very passive. The formation of such an arc-shaped chain is like a chain that holds the throat of our country. Although we put the overall situation first and remain patient, this military group has intensified its efforts to maintain the existing situation. But if this situation is deadlocked for a long time, it will hinder the great cause of national reunification and the pace of China's rise. The situation in the east of our country is very steep! In the northern border of our country, the dream of Russia's great power rejuvenation has been rekindled, and the chauvinism of great power, the tradition of being stronger than external expansion, Mongolia's limited resources, geographical defects and great nationalist tendencies have added intangible but huge hidden dangers to the stability of this region. Russia's eastern resources are extremely rich and far from being fully exploited. With the world's energy constantly exhausted and countries' demand for oil and mineral resources is increasing, this region is likely to become the lifeline of Russia's revival, and it may also be robbed by Japan, which is poor in resources, and the United States, which is in great demand for resources. Once imperialist countries like the United States and Japan intervene in northern China, it will aggravate the already unstable situation in this region and make us unable to sleep peacefully. In Central Asia and South Asia, China's two major separatist forces, regional terrorist forces and India, which don't want to see the strength of China and covet the superior resources in the southwest border of China, have shady close activities. In addition, Russia's inability to control Central Asian countries has provided a convenient gap for American imperialists, and the United States has long occupied the Middle East with ulterior motives, forming another arc chain related to the lifeline in China's vast western frontier. In China's oceans, especially in the southern waters of China, small countries that have been envious for a long time, such as Thailand, Vietnam, Malaysia, Indonesia, the Philippines, etc., today, lions have opened their mouths again and again and wantonly embezzled and encroached on the southern waters of China and some islands without scruple, which has seriously affected China's international image, greatly affected China's oil transportation from the Middle East, and plundered China's rich marine resources. If these countries occupy this area with the support of the U.S. imperialists, then the southern part of China will soon form another shackle, and then the four directions of China's southeast, northwest and northwest will be completely trapped in the U.S. military encirclement directly or indirectly, and then China's strength and rise will be in the foreseeable future! Obviously, the surrounding environment of our country is not optimistic at present. Born in sorrow, died in happiness. Only by deepening the understanding of crisis and suffering can we stand firm in this world, cope with all kinds of challenges and grasp the final direction of the current situation. Nothing more than a country. If there is a country, there is defense, and if there is no defense, it will not stand. National defense is the product of the country's survival, development and security needs, and its strength is directly related to the country's life and death, rise and fall, honor and disgrace. Since there are still unsafe and unstable factors in the surrounding areas of our country, the best and most effective way is to continue to build a strong national defense force. Only by such full preparation can we achieve "the enemy will block us, and there is plenty of means to cover us", and we can achieve "if people don't attack me, I won't attack, and if people attack me, I will attack", and we can say that "all reactionaries are paper tigers" is like "attacking me"
