Japan's Aegis anti-missile system was once called the first in Asia for a long time.
After World War II, Japan's pacifist constitution stipulated that only defense forces, including the former Air Self-Defense Force, could be developed, which was a counterbalance to the Soviet Air Force. As you know, the August 8th Fleet of the Maritime Self-Defense Force is powerful, and its capability and efficiency have been highly recognized by the United States and other western countries. The self-defense forces on the road are also very strong in mine clearance and helped the United States in the Iraq war. Therefore, its strong defense ability is an innate factor. In recent years, there have been many advanced offensive troops, including the recent Marine Corps, but this is only his word, and it is hard to say that the offensive troops have not gone through actual combat.
In addition, Japan's anti-submarine capability is also superb. The quasi-aircraft carrier "Sunward" designed by him is mainly equipped with anti-submarine helicopters, and its performance is also the first in Asia. And he doesn't have a nuclear-powered submarine, but the mute ability of conventional submarines is stronger than any of our active submarines.
Compared with Japanese, China's strong army still has a long way to go. The reason why Japanese and American dogs didn't invade our China by force was because the combat power of our Second Artillery Corps was unpredictable. We have never been able to use force to deal with island disputes with the Philippines and Japan. The bottom spirit does not come from cynical slogans, but from the development of national strength and the sense of urgency that has always been maintained.
