The security around China is still 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 and rich resources, and South Korea's psychology of 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 a situation unfavorable to China on land and at sea. Moreover, Taiwan Province Province and Diaoyu Island may break out at any time, and because these two regions have natural strategic advantages, they are closely related to their interests. In case of violent conflict, 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 this arc-shaped chain is like a chain that holds the throat of our country. Although we focus on the overall situation and remain patient, this military group has intensified its efforts to maintain the status quo. However, if this situation persists for a long time, it will hinder the great cause of national reunification and the rise of China. The situation in eastern China is very steep! In the northern border of our country, Russia's dream of great power rejuvenation has been rekindled. The chauvinism of great power, the tradition of being stronger than external expansion, Mongolia's limited resources, geographical defects and great nationalism have added intangible but huge hidden dangers to the stability of this region. The resources in eastern Russia are extremely rich and far from being fully developed. With the continuous depletion of energy in the world and the increasing demand for oil and mineral resources in various countries, 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 needs huge 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. In Central Asia and South Asia, China's two separatist forces, the regional terrorist forces and India, do not want to see China's strength, covet the superior resources in the southwest border of China, and have shady intimate activities. In addition, Russia's inability to control Central Asian countries has provided a convenient gap for American imperialists. The United States has occupied the Middle East with ulterior motives for a long time, forming another arc chain related to the lifeline in China's vast western frontier. In the ocean of China, especially in the southern waters of China, there are small countries that have long been envied, such as Thailand, Viet Nam, Malaysia, Indonesia and the Philippines. Up to now, lions have opened their mouths again and again, wantonly embezzled and occupied China's southern waters and some islands, which 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, China's south will soon form another yoke, and then China's four directions, 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 gain a firm foothold in this world, meet various challenges and grasp the final trend of the current situation. There is no more than one country. If there is a country, there is defense, and if there is no defense, there will be no defense. 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 have sufficient means to cover us", achieve "people will not attack me, I will not attack, and if people attack me, I will attack", and say that "all reactionaries are paper tigers", just like "attacking me"
