World peace and development are facing new tests and challenges. 2. at home. China is in a period of rapid development of socialism, the domestic situation is stable, and the people's material and cultural living standards are constantly improving. In the period of social transformation, social contradictions are complicated, all kinds of bad forces try their best to infiltrate, money worship, hedonism and other bad ideas are partially rampant, and a few people with ulterior motives try to provoke regional and ethnic contradictions. The task of security and stability is of great responsibility. 3. Social perspective. The transformation of social form to comprehensive informatization plays a decisive role in future economic, political and military development and struggle. The modern military combat effectiveness displayed by the United States in the wars in Iraq and Afghanistan is thought-provoking, which indicates that information warfare will become the main form of military war in the future. 4.
