But it is an indisputable fact that North Korea has been bullied by Japan since ancient times. During the Tang Dynasty, Silla, the regime on the Korean Peninsula, was invaded by the Japanese navy. However, in the face of the huge Tang Dynasty, the Japanese army was simply vulnerable, and 43,000 troops were directly attacked by 1.3 Tang Jun.
Then there is the famous Wanli Korean War. North Korea at that time was even more vulnerable. In just two months, he was beaten by the Japanese army. "The three capitals defended the arrow and collapsed on all sides." Finally, the Ming army drove the Japanese away. Later, in modern times, Japan, which became strong through the Meiji Restoration, made a comeback and invaded North Korea. North Korea was not so lucky this time, because the Qing Dynasty was backward and corrupt and became a defeated country in the Sino-Japanese War. So North Korea was soon directly annexed by Japan.
In fact, this truth was pointed out by Toyotomi Hideyoshi when he invaded North Korea, and there are only four words: "False way into the light"!
As an island country, Japan has a small territory, poor resources and frequent earthquake disasters. Therefore, the Japanese have had a heavy mainland plot since ancient times, and they are bent on crossing the sea to invade the East Asian continent in an attempt to invade China. The ideal springboard for invading the mainland is the Korean Peninsula opposite Ma Haixia.
Because North Korea is not only weak, but also close to Japan, it is easier to be occupied by them. Therefore, every time Japan expands abroad, it will start from North Korea.
In fact, this question is not difficult to answer. The weakness of ancient Korea was not only caused by the small land area and population. It is also because they have long pursued "great events" in diplomacy, which makes them almost useless.
In ancient times, Korea was weak and was no match for China's unified dynasty. China dynasty took good care of its vassal states, as long as they were "not dead, they generally wouldn't die". Therefore, North Korea simply "pursues greatness" in an all-round way, respects China everywhere, pays tribute every year, and comes to the DPRK every year, so that it can be protected by the China Dynasty.
The most typical one is the Lee Dynasty in North Korea, which lasted from 1392 to 19 19, and the country was as long as 5 19. The secret of its longevity is that things are big. During the Ming dynasty, they were Daming's security vassal countries; After the rise of the Qing Dynasty, they became vassals of the Qing Dynasty. In this way, under the protection of the China Dynasty, North Korea was able to enjoy the whole country for more than 500 years, until the Qing Dynasty was defeated by Japan, and it could no longer provide them with protection.
However, the all-round "big doctrine" has caused a very obvious drawback, that is, the military equipment is lax and the military strength is weak. When Japan rebelled, Korea had been at peace for a long time. "For more than 200 years, people have never known soldiers." Therefore, in the face of the Japanese invasion, the Korean army devastated by the war was simply vulnerable.
