On the basis of the development of modern industry, modern agriculture, and modern science and culture in our country, the building of national defense must not only ensure effective preparations for active defense. It must also be ready, should imperialism launch an aggressive war against China, to launch a strategic counteroffensive and a strategic pursuit after defeating the enemy—driving the aggressors back to their own territory and resolutely, cleanly, and completely annihilating them. In this way, we can liberate the people there, so that such wars of aggression will never occur again. To this end, in addition to continuing to strengthen the Army and the Air Force, we must vigorously develop the shipbuilding industry and establish maritime rail links, with the aim of building a powerful naval combat force within the next few years.
