In World War II, one of the countries that was the most ruthless to Japan, 200,000 Japanese troops were almost completely destroyed, and I still have lingering feelings

Japan suffered the worst casualties in the entire World War II campaign caused by the United States. With just one atomic bomb, the United States killed Japan 130,000 people in a single day, not counting the number of casualties. But the United States is not the country that treats Japan the most severely, before dropping the atomic bomb, the United States threw tens of thousands of leaflets over Japan to evacuate civilians, and after the war also helped Japan rebuild after the war. Australia is the country that treats Japan the most harshly.
After the Attacks on Pearl Harbor, the United States declared war on Japan, and australia followed suit in declaring war on Japan. At that time, Japan did not commit acts of aggression against Australia, and Australia declared war in response to Japan's annexation ambitions. After the Attack on Pearl Harbor, although the United States joined the war, they were still afraid of Japan's behavior of not being afraid of death, and they were afraid of fighting. But Australia is different, the ignorant are not afraid, they see the Japanese soldiers and go up desperately, not afraid at all.
In the Battle of New Guinea, the American general MacArthur implemented the "frog jumping tactic", established a series of naval and air military bases around the coast of New Guinea, and 200,000 Japanese troops were trapped on the island by the Australian army, and supplies were cut off. The Australian shells directly blew the Japanese out of the air raid shelter, and the Japanese could only hide in the hole and stay on the island in the desperate rainy season to wait for rescue. However, foreign aid was delayed, and after two months, the Japanese finally could not hold out and chose to surrender.
When the Japanese surrendered, less than 10,000 of the 200,000 troops on the island were left, and it can be said that the entire army was almost destroyed. The battle was a crushing situation, with the Australians defeating 200,000 Japanese troops with almost no casualties and buying time.
At that time, it was often raining in New Guinea, and the Japanese army hid in the cave and suffered from skin diseases, and their bodies were already festering, and the wounded would eventually die alive. Abe once went to New Guinea during a visit to Australia and talked about the search for japanese bodies, but only about 20,000 were found, and 170,000 were missing. This battle has also become a shadow in the hearts of the Japanese army, and it is still mentioned in the heart.
