Why didn't the United States drop the atomic bomb on Tokyo?

The atomic bomb belongs to nuclear weapons and is strategic equipment. Since this kind of equipment is used, strategic issues are of course considered, so the atomic bomb is not thrown away whenever it wants. The United States thought twice before dropping the atomic bomb, and Roosevelt was not crazy, although Einstein thought that Roosevelt's agreement to use the atomic bomb was actually the same as Hitler's.

after the battle of midway and other battles, the U.S. military gradually grasped the initiative of World War II. The Japanese navy has been completely defeated, and American planes are constantly hovering over the Japanese empire. At this time, what the United States has to consider is not how to die with Japan, but how to make Japan surrender and end the war as soon as possible. Because the European battlefield is clear at this time, it is not good for the United States if the war in the western Pacific continues to be deadlocked. Moreover, at this time, the Soviet Union has already sent troops to the Northeast. If the Soviet Union takes the lead, the United States will have no place in the Asia-Pacific region.

But at this time, the trouble is in front of us: only the emperor in Japan can declare surrender, and all the imperial troops are working for the emperor, and they are determined to "fight a decisive battle at home". In other words, these Japanese troops are ready for the larger foe. If the American troops land by conventional means, they will not only suffer heavy casualties, but also delay the war and further drag themselves into the abyss of war.

after evaluation, the us military believes that if the conventional "Normandy landing" is adopted, a full-scale tragic war will break out, and the number of casualties may reach millions. Japan's desperate resistance will also spread to the innocent and cause more serious consequences. Therefore, nuclear weapons must be used to order the emperor to surrender through nuclear threats. By the way, the US military can accept Japan's surrender and naturally occupy Japan.

Therefore, the significance of dropping two atomic bombs by the US military lies in prompting the Emperor to declare surrender and let the US military occupy Japan. If the atomic bomb is dropped directly on Tokyo, it will arouse public indignation in Japan, and even the Japanese will be willing to surrender to the Soviet Union rather than buy the account of the US military. Therefore, the US military chose Hiroshima and Nagasaki as dropping points. These two cities were both important heavy industry hubs in Japan at that time, and Hiroshima was also a research base of toxic gas in Japan. The dropping here was well-founded, which could abolish Japan's military industry and also cause great shock to Japan: if the emperor does not surrender, it is hard to say where to drop the next atomic bomb.

Sure enough, under the deterrent of the power of the atomic bomb, the emperor decided to order surrender after considering the final interest. Japan has always been under the actual control of the United States, which is the strategic effect brought by the use of strategic weapons. Although many people died in two cities in Japan because of atomic bombs, if hand-to-hand combat broke out, the number of casualties might be even higher. Therefore, the US military considered this to be a "lesser of two evils", which was barely an acceptable result.
