1840 The Sino-British Opium War broke out, which led to the signing of the treaty of nanking, the first unequal treaty in China's modern history. Since then, the door of "China Power" has been opened, and the Chinese nation has entered one national defense crisis after another. China's modern national defense history is full of humiliation, bitterness and tragic. With the signing of one unequal treaty after another, China began to be semi-colonial and semi-feudal, and was forced to open trading ports and concessions everywhere along the Yangtze River. All transportation undertakings in China are monopolized by foreign powers, and foreign troops are stationed everywhere in China. The whole of China has been divided into several imperialist spheres of influence, and it has completely become a defenceless country, which is in turmoil all day. After the overthrow of the feudal monarchy, the warlords who were unfortunately supported by the imperialist powers scuffled and the society suffered even greater damage! Later, when World War II broke out, Japanese imperialism invaded China on a large scale, which brought a painful disaster to the people of China! In more than half a century before the founding of 1949 People's Republic of China (PRC), China's sovereignty suffered serious losses, its territory was ceded, and a large amount of post-war reparations were paid. The country was poor and weak, and its people suffered greatly!
History is a mirror. The painful lesson of China's modern history tells us that national defense is backed by economic base, and Qiang Bing must get rich first, and the two should develop in harmony. Economic construction is the basic support of national defense construction. Without economic construction, national defense construction is out of the question. National defense strength is an important part of comprehensive national strength. Without national defense construction, it is difficult to guarantee a safe environment for economic construction. Therefore, while concentrating on economic construction, we must earnestly strengthen national defense construction, so that national defense construction and economic construction can develop in harmony and form a good situation of mutual promotion.
History also clearly tells us that national unity and national unity are the key to a strong national defense. Throughout the history of national defense in China for thousands of years, national defense is strong in any period of national unity and national unity; Whenever the country is divided and ethnic contradictions are acute, national defense is weak. In the late Qing Dynasty, faced with the attack of western powers, not only did they dare to launch an anti-aggression war, but they did not rely on or support the people to wage war. On the contrary, they believe that "suffering comes not from the outside, but from the inside" and that "preventing people is more important than preventing fire". The policy of suppressing the anti-aggression struggle spontaneously organized by the people eventually led to repeated wars and defeats, land expropriation and compensation, and gradually became a semi-colonial and semi-feudal society. During the War of Resistance against Japanese Aggression period, under the advocacy and organization of China, the anti-Japanese national united front was established. Under the condition that the enemy was strong and we were weak, China adhered to the strategy and tactics of the people's war, fully mobilized and organized the people, United all anti-Japanese forces, and jointly fought against aggression, and finally won an all-round victory in War of Resistance against Japanese Aggression. Therefore, in the great new era, we should strive to safeguard the reunification of the motherland and national unity, and carry out the most determined struggle with those enemies who attempt to split our great motherland! !
2 1 century is an era of highly developed information and technology, and scientific and technological progress is an important force for strong national defense! National defense construction has always been the main field of advanced technology competition in the world. Advanced weapons are important after all, and science and technology cannot be ignored. In the field of national defense science and technology, we should focus on developing some key technologies. Mastering these technologies is the need to realize China's military strategy in the new period, and it is also the need of the whole modernization. It is the military strategic policy of our army in the new period to carry out active defense and focus on winning local wars under modern technology, especially high-tech conditions. Around this policy, we will meet the challenge of world military development with the spirit of reform and innovation and do everything possible to build our military weapons and equipment. To sum up, development is the last word and the first priority, and you will be beaten if you fall behind! As contemporary college students, we have the responsibility and obligation to learn scientific and cultural knowledge, master professional skills and cultivate ourselves into useful people from now on. After entering the society, we will contribute all our strength to the development of our economy, the progress of our science and technology, the construction of our modern socialist language and the prosperity of our national defense. Strive for the great rejuvenation of the Chinese nation for life! !
