According to the data of World War II, Japan refused to surrender after the United States dropped the first atomic bomb on Hiroshima and the second atomic bomb on Nagasaki. Why?

Because when the United States dropped the first atomic bomb on Hiroshima, Japan thought that the United States had only one atomic bomb and that Japan would not be attacked by atomic bombs again, but the United States dropped the second atomic bomb and Japan surrendered because it was afraid that other cities would also be attacked by atomic bombs.

1in the summer of 945, Japan was defeated, but Japan's crazy resistance in Okinawa and other places led to a large number of allied officers and soldiers casualties. In order to protect the lives of allied officers and soldiers, force Japan to surrender as soon as possible, and also to contain the Soviet Union, US President Truman and senior military officials decided to drop atomic bombs in Japan to speed up the war process.

1on August 6, 945, the us military dropped an atomic bomb on Hiroshima, Japan, causing a large number of civilian and military casualties. The Hiroshima incident did not make Japan immediately agree to accept the Potsdam ultimatum, that is, unconditional surrender.

They tried to cover up the truth about Hiroshima, claiming that a meteorite had landed in Hiroshima. He believes that the US military has only one atomic bomb, and he also hopes for the mediation of the Soviet Union.

On August 9, the United States dropped its second atomic bomb on Nagasaki, Japan. There were 270,000 people in Nagasaki, and more than 60,000 people died that day.

After two atomic bombs were bombed, Japan was extremely worried about the third atomic bomb. Chose unconditional surrender.

Extended data:

According to the plan, the US military will determine the bombing sites according to the weather conditions: Kyoto, Niigata, Hiroshima, Kokura, and Nagasaki was added later.

Unlike the image of "city of peace" that has been desperately displayed to the world for more than half a century, Hiroshima was a military city at that time.

It is the second general headquarters of Japan's local defense forces and the military administrative region of China (Japanese place name, located in the central region).

Nagasaki is one of the most important shipbuilding bases in Japan. Kokura is a weapon industrial city in Kitakyushu, Japan. Other alternative targets: Niigata is also a weapon industry city or a chemical industry city.

Kyoto was deliberately forgotten by the US military in the previous bombing, accumulating a large number of arsenals and residents who moved from surrounding areas. Tokyo is the political and economic center of Japan.

1945 at 8 o'clock on August 6, three American B-29 planes entered Hiroshima from high altitude. At this time, many Hiroshima citizens did not enter the bomb shelter, but looked up at the American plane.

Prior to this, the B-29 had flown into Japanese airspace for several days for training, but this time, one of the three planes had loaded a 5-ton atomic bomb. At this time, I was ordered to bomb Hiroshima.

At 9: 00 14 minutes 17 seconds, when the sight on a B-29(44-86292) loaded with atomic bombs aimed at the center of a bridge in Hiroshima, the automatic bomb dropping device started. After 60 seconds, the atomic bomb fell into the air from the open hatch.

At this time, the plane 155 turned and swooped down; In an instant, the flying height dropped by more than 300 meters. This is done to stay as far away from the scene of the explosion as possible.

Forty-five seconds later, the atomic bomb exploded in the air 600 meters above the ground (the specific location is 600 meters above the island hospital west of Xiangsheng Bridge in Hiroshima Prefecture, Japan/0/00 meter of Kloc), and then it gave off a dazzling white flash, followed by a deafening explosion over the center of Hiroshima.

In an instant, the city suddenly rolled up huge mushroom-shaped smoke clouds, and then hundreds of pillars of fire were erected, and Hiroshima immediately became a searing sea of fire.

On August 9, the US military prepared to bomb the second target warehouse, and took Nagasaki as an alternative. However, the weather in the small warehouse is very unfavorable. The bomber "Bok's car" with an atomic bomb shuttled through the clouds three times and still failed to find a gap. Finally flew to the second target Nagasaki.

A commando team consisting of five B-29 bombers dropped the atomic bomb "Fat Man" on the center of Nagasaki. "Fatty" is a plutonium bomb, about 3.6 meters long, with a diameter of 1.5 meters and a weight of about 4.9 tons. TNT equivalent is 22,000 tons, and the explosion height is 503 meters. The bombing caused more than 654.38+10,000 people in Nagasaki's population of 230,000 to be killed or missing that day, and 60% of the buildings in the city were destroyed.
