Japan and Taiwan, China cannot invade Chinese Mainland together.
You might as well join the rest of the world, but you basically understand this. Perhaps, if you join Europeans, we will begin to talk about the large-scale promotion of the West with the help of Russia after years of preparation and construction, but in addition
China has 7 million armed personnel and a huge mechanized force. They can try to keep the Soviet Union and the United States away from Chinese territory. Large areas of land are specially equipped for strategic withdrawal. Most of them still remember the suffering caused by few Japanese. Oh, did I mention nuclear weapons? Well, nuclear weapons.
Seriously, please forgive this tone, but if militarist Japan did not do this when China was at its weakest, how should a peaceful Japan do after 80 years of China's full armed forces? In the face of a large country with nuclear weapons, 1.4 billion people, and a strategic land area as large as the Urals.
I am not saying that China is particularly powerful, but that invasion is a very bad way of war. After all, the efforts of the United States and the Soviet Union to "liberate" Afghanistan have failed.
