We all know that there have been many wars in history, in fact, the two biggest purposes of fighting between countries and countries are land and resources. This is indispensable for national development, and one of the drawbacks of Japan's development is that the country's territorial area is very small, which can be reflected as early as history, and the Japanese government is also very troubled by this problem, so they began to choose to expand their territorial scope and resources through continuous expansion, so in history there have been incidents of Japanese aggression against the country.

Japan's development began after the Meiji Restoration, and the process of modernization began, but in the process, they found a serious problem, the land area is small, just an island, with the rise of sea level in the future, this island country will be dangerous, so they will turn their attention to other countries that are closer to them overseas.
At the time of World War II, Europe was under the rule of fascism, so Japan, which was deeply affected, extended its claws to other countries in Asia, and in the decades of its conquest, it brought great disasters to many countries in Asia. At the beginning, the most unfortunate country was North Korea, the area of North Korea is also very small, not large, so Japan does not pay attention to North Korea at all, North Korea is so small place can not feed Japan at all, so at that time the Qing Dynasty was in a weak state, plus the surrounding countries are busy with their own country's war, so Japan quickly began to attack the Qing Dynasty, in the Qing Dynasty fiercely fished.
They even made wild remarks that they wanted to annex the whole of China in three months, of course, this was just their fantasy, even if the Qing Dynasty was weak at that time, it still fought with Japan for more than ten years, and it has been inseparable, and finally, it ended in our victory, which also shattered what Japan said at that time. Of course, in addition to the unity of our people, our country also occupies a great advantage in terms of land area and population, so we can fight a protracted war, but Japan cannot, so in the end Japan has to withdraw.
In fact, in addition to our country, Japan has also attacked this Asian country, this country is similar to our country in terms of land area and number, I think you can guess that this country is India, but the outcome is different from our country, although we won but also spent a long time with Japan, and India only fought a war with Japan, Japan withdrew, why is this?
How can a country with such a huge ambition in Japan willingly give up india's fertile land and resources, in fact, there are three reasons, one of which is that India was a British territory at that time, so there were many British soldiers in the country, and Japan was naturally afraid. The second is that the distance between India and Japan is still relatively far, so it is difficult to transmit Japan's military supplies after the war, which is very unfavorable to Japan's military intelligence.
The most important thing is the third point, we all know that India belongs to the tropical monsoon climate, so the weather on its side is very hot, it is easy to cause the occurrence of diseases, and the speed of transmission is also very fast, which is why there are many places in India that can not get rid of the disease, at that time many soldiers in Japan can not stand such weather, and also suffered from a variety of diseases, to the medical conditions at that time must be no rule of law, so before they began to fight, Japan will lose a lot of soldiers, if you continue to fight, I'm afraid I can't eat and go around.
