In recent ten years, when the United States was caught in arduous guerrilla warfare in the deserts and mountainous areas of the Middle East and Central Asia, China and Russia spared no effort to develop modern weapons and equipment and greatly improve their modern warfare capabilities. If there was still a technological gap between China and the US military 20 to 30 years ago, the pure technological gap between China and the US is only about 5 to 10 years now, and it has even been leveled or surpassed in some fields.

Because "science and technology are the primary productive forces", the United States has become a powerful country that can "dominate the world". Since the second half of the 20th century, high technologies such as computer, communication, biology and medicine in the United States are changing the whole earth. Even the face of the universe has changed with the development of their technology.
