Why were Hiroshima and Nagasaki chosen for the atomic bombings?
The Japanese refused to surrender so Truman thought it was necessary to bomb Hiroshime. After the Japanese still hadn't surrendered, Nagasaki was bombed, forcing Japan to admit defeat because their war effort could not continue to succeed after the attack

Answer . \nThe United States, and more directly a crew of the USAF who flew the aircraft that dropped both bombs on Japan.\n. \nJim B. Toronto.
WHO: \nallied forces, \nWHY: In order to prevent the inevitable invasion of mainland Japan and causing further causalities than the atomic bombing did. \nEffect: saving thousands of lives which would have been otherwise lost had Japan not surrendered to the Allied Forces.
Answer . That is a very opinionated question. The justification from the American side was that the nation of Japan still had around 4 millions soldiers and extensive fortifications on the islands, making an invasion very costly in life. It was thought that in the first 6 months 600,000 American …boys would die during an invasion of Japan. So Truman decided to spare 600,000 American soldiers at the cost of the deaths of over 100,000 civilians and the complete destruction of two cities. What he nor his advisors knew was the horrific destruction the bomb caused. I think if he had known that, the bombs might not have been dropped. ( Full Answer )
Those two cities were industrial and Truman thought that bombing them would cripple the Japanese economy.
Yes, so I posted link with power point presentation on the bombings in the related links box below.
There were several considerations in choosing the site for the first bomb.. The target should be an urban area of at least three miles diameter; . The target should be capable of being effectively damaged by a blast; . The target should not have been a previous target of conventional bombs, so th…at the damage from the single new bomb could be evaluated (both by the US and the Japanese governments) on its own. . Hiroshima met all these criteria, and in addition was a significant military site.. Nagasaki was actually not the first choice for the second bomb; the city of Kokura was the intended target and the bomber made three passes over Kokura before being directed to the secondary target of Nagasaki due to heavy cloud cover at the primary site. Nagasaki was a major Imperial Japanese Navy port and, though it had been bombed previously, had not suffered extensive damage. ( Full Answer )
Many self-serving reasons have been advanced for justifying Truman's decision, such as the objective of saving the lives of American soldiers by shortening the war in the Pacific and avoiding a military invasion of Japan with a quick Japanese surrender. That surrender came on August 14, 1945 and it …was made official on September 2 with the signing of the Japanese Instrument of Surrender, nearly one month after the bombing of the cities of Hiroshima and Nagasaki. Nazi Germany had capitulated on May 8, 1945 and World War II was already over in Europe. There was also the diplomatic fear that the Soviet Red Army could have invaded Japan, as they had done in Berlin, thus depriving the United States of a hard fought clear-cut victory against Japan.

"Little Boy" was dropped on the city o Hiroshima on Monday, August 6, 1945, followed on August 9 by the detonation of the "Fat Man" nuclear bomb over Nagasaki.
Then many lives would have been lost because if the bomb hasn't been dropped many more lives would have been lost. Casulties would have increased also. The war would have went longer also.
the two atomic bombs were dropped on Hiroshima and Nagasaki so the U.S.A could end the war with Japan, hence ending WWII
Japan and the US were at war, Japan having attacked the US and Great Britain. After 4 years of war, the Allies had pushed the Japanese back to the home islands, and were looking at the prospect of having to invade the Japanese homeland, with an estimated death toll of 1 million Allied servicemen. Ja…pan had been warned about the atomic bomb, but refused to surrender. After Hiroshima was bombed, Japan was warned again, and again, refused to surrender. After a second atomic weapon was used on Nagasaki, Japan surrendered. ( Full Answer )
'Little Boy' on Hiroshima was a uranium bomb and 'Fat Man' on Nagasaki was a plutonium bomb. Little boy was the name of the nuclear bomb dropped on Hiroshima. It was dropped on August 6, 1945 from a B29 airplane. Uranium was used as fuel. Fat man was the name of the nuclear bomb dropped on Nagasaki.… It was dropped on August 9, 1945 from a B29 airplane. Plutionum was used as fuel. Little Boy and Fat Man. On August 6, 1945, at 9:15 AM Tokyo time, a B-29 plane, the "Enola Gay" piloted by Paul W. Tibbets, dropped a uranium atomic bomb, code named "Little Boy" on Hiroshima, Japan's seventh largest city. In minutes, half of the city vanished. According to U.S. estimates, 60,000 to 70,000 people were killed or missing, 140,000 were injuried many more were made homeless as a result of the bomb. Deadly radiation reached over 100,000. In the blast, thousands died instantly. The city was unbelievably devastated. Of its 90,000 buildings, over 60,000 were demolished. Another bomb was assembled at Tinian Island on August 6. On August 8, Field Order No.17 issued from the 20th Air Force Headquarters on Guam called for its use the following day on either Kokura, the primary target, or Nagasaki, the secondary target. Three days after Hiroshima, the B-29 bomber, "Bockscar" piloted by Sweeney, reached the sky over Kokura on the morning of August 9 but abandoned the primary target because of smoke cover and changed course for Nagasaki. Nagasaki was an industrialized city with a natural harbor in Western Kuushu, Japan. At 11:02 a.m., this bomb, known as the "Fat Man" bomb, exploded over the north factory district at 1,800 feet above the city to achieve maximum blast effect. Buildings collapsed. Electrical systems were shorted. A wave of secondary fires resulted, adding to their holocaust. Flash burns from primary heat waves caused most of the casualties to inhabitants. Others were burned when their homes burst into flame. Flying debris caused many injuries. A fire storm of winds followed the blast at Hiroshima as air was drawn back to the center of the burning area. Trees were uprooted. The bomb took the lives of 42,000 persons and injured 40,000 more. It destroyed 39 percent of all the buildings standing in Nagasaki. According to U.S. estimates, 40,000 people were killed or never found as a result of the second bomb. ( Full Answer )
The two bombs that were dropped on Hiroshima and Nagasaki ended the war with Japan, hence ending WWII
JAPAN ACCEPTED AMERICAN TERMS FOR SURRENDER On the ground moments before the blast it was a calm and sunny Monday morning. An air raid alert from earlier that morning had been called off after only a solitary aircraft was seen (the weather plane), and by 8:15 the city was alive with activity -- s…oldiers doing their morning calisthenics, commuters on foot or on bicycles, groups of women and children working outside to clear firebreaks. Those closest to the explosion died instantly, their bodies turned to black char. Nearby birds burst into flames in mid-air, and dry, combustible materials such as paper instantly ignited as far away as 6,400 feet from ground zero. The white light acted as a giant flashbulb, burning the dark patterns of clothing onto skin (right) and the shadows of bodies onto walls. Survivors outdoors close to the blast generally describe a literally blinding light combined with a sudden and overwhelming wave of heat. (The effects of radiation are usually not immediately apparent.) The blast wave followed almost instantly for those close-in, often knocking them from their feet. Those that were indoors were usually spared the flash burns, but flying glass from broken windows filled most rooms, and all but the very strongest structures collapsed. One boy was blown through the windows of his house and across the street as the house collapsed behind him. Within minutes 9 out of 10 people half a mile or less from ground zero were dead. No one will ever know for certain how many died as a result of the attack on Hiroshima. Some 70,000 people probably died as a result of initial blast, heat, and radiation effects. This included about twenty American airmen being held as prisoners in the city. By the end of 1945, because of the lingering effects of radioactive fallout and other after effects, the Hiroshima death toll was probably over 100,000. The five-year death total may have reached or even exceeded 200,000, as cancer and other long-term effects took hold. At 11:00 a.m., August 6 (Washington D.C. time), radio stations began playing a prepared statement from President Truman (right) informing the American public that the United States had dropped an entirely new type of bomb on the Japanese city of Hiroshima -- an "atomic bomb." Truman warned that if Japan still refused to surrender unconditionally, as demanded by the Potsdam Declaration of July 26, the United States would attack additional targets with equally devastating results. Two days later, on August 8, the Soviet Union declared war on Japan and attacked Japanese forces in Manchuria, ending American hopes that the war would end before Russian entry into the Pacific theater. By August 9th, American aircraft were showering leaflets all over Japan informing its people that "We are in possession of the most destructive explosive ever devised by man. A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2,000 of our giant B-29s can carry on a single mission. This awful fact is one for you to ponder and we solemnly assure you it is grimly accurate. We have just begun to to use this weapon against your homeland. If you still have any doubt, make inquiry as to what happened to Hiroshima when just one atomic bomb fell on that city." Meanwhile, Tibbets's bomber group was simply waiting for the weather to clear in order to drop its next bomb, the plutonium weapon nicknamed "Fat Man" (right) that was destined for the city of Nagasaki. because they felt like it ( Full Answer )
One View: According to President Truman and most of the civilians at the time, it was. Another View: Morality in War: While protesters bring about issues of morality, the fact remains that WWII itself was caused by immoral desires to expand empires (and kill all nay-sayers) and to establi…sh Aryan superiority (Hitler personally wanted to use WWII to wipe out the untermensch; the subhuman peoples such as Jews and "Gypsies".) Therefore, morals cannot apply to a war where immorality runs rampant; we can only debate whether the bombings were more humane and beneficial than the situation without it. Atomic bombings were more beneficial (to both Japan and U.S.) Japan won't surrender: Unfortunately, the Japanese, in evidenced manners (quotes to actions), were not going to surrender. While the U.S. initially demanded unconditional surrender, they later gave a revised offer, with notable aspects saying: . Japan's territories will be limited to its main islands like Kyushu, Honshu, Hokkaido, etc. (it will lose its colonial empire) . Japan will not be enslaved as a race nor destroyed as a nation, and fundamental human rights as well as a democratic government will be established . Japan will disarm its military forces NOTE: contrary to what many said, the U.S. never mentioned anything about the emperor (many uneducated opposed of the Atomic bombings mention that the U.S. demanded the emperor to resign from his position, but that was never said in the POTSDAM declaration, the Allied ultimatum for the Japanese) The Emperor was not truly in control: In addition, the military wing of Japan headed by Hideki Tojo refused to surrender, and even attempted 3 coup de etats against the emperor. Since the military held the real political power, Japan can be concluded as not willing to surrender. The emperor's confident, Koichi kido, admitted that the atomic bombing was the only solution to have Japan surrender (read previous sentences). Japanese terms of surrender disregarded punishments for War Crimes. The Japanese wanted the following surrender terms: . Leave disarmament and demobilization to Imperial general headquarters . No occupation of the Japanese home islands, Korea, or Formosa (Thailand) . Delegation to the Japanese government of the punishment of war criminals. Japan's Proven Willingness to Kill Civilian Populations: Japan had demonstrated a willingness to win military victories at all costs and then control the area taken with routine acts of brutality. Over 3 Million Korean Civilians were killed under Japanese Military occupation. The Chinese had also suffered under the forced military rule of Imperial Japan. Millions of Chinese were killed. Many Chinese were subjected to experiments similar to those carried out by the Nazis in the European Prison Camps (Holocaust); this would include experiments of bio weapons on live humans. The Rape of Nanking is marked as a day of open Chinese civilian slaughter by Japanese military forces. Alternatives are even worse: The only viable alternative therefore (since Japan won't surrender), is Operation Downfall. I won't go into detail with this as this section will take pages, but this is the summary: Operation Downfall: U.S. invasion of Japan (below is its summary). . Average Estimated U.S. casualties= at least 200,000~300,000 . Average Estimated Japanese casualties = in the millions. . Highest estimate of U.S. casualties: 1.7~4 million casualties . Highest Japanese Casualties: 5~10 MILLION Estimated U.S. losses were factual : Consider that the U.S. 96th Infantry Division alone had lost some 10,000 U.S. Army Soldiers Killed In Action or Missing In Action (not accounting for wounded) by the end of the Campaign to take Okinawa, the first major Japanese island home territory. The U.S. Marines endured loses in the thousands of Marines for the taking of Iwo Jima an island mere miles in measured size. Iwo Jima was not considered Japanese home territory as Okinawa was. Mass Warfare: The full invasion of Okinawa involved more men and naval vessels than that of the D-Day Invasion in Europe (less aircraft). To invade mainland Japan would mean the required assembly of the largest military invasion force in recorded history. Japan Shows Signs of Civilian Combatants: On Mainland Japan the Imperial Forces were constructing miles of underground entrenchments. Civilians were training with rifles to mere farming tools to meet the American invasion forces. Veteran U.S. soldiers would have destroyed a civilian force in ground combat alone. Fire Bombings Failed: Fire-bombing campaigns were causing mass devastation of the Japanese Mainland Islands, yet were not effective at bringing an end to Military action. Incendiary bombs were deployed into Japanese cities to cause mass fires. The fire bombings were extremely effective for military needs, yet failed to end Japanese resistance. Fire bombing campaigns reduced manufacturing of war materials, eliminated new food supplies, burned down entire cities, and caused general devastation to Japanese military and civilian lives. Disbelief in the Atomic Bomb: Many Japanese Imperial Military and Government leaders actually believed the first atomic bomb to have been a mere large fire bombing. Imperial Military leaders were known to continued to refuse surrender after the second atomic bombing. However, essential Japanese Military Leaders were also in favor of unconditional surrender. These few men enabled the Emperor of Japan to seek an end to military actions successfully. Japanese Military and Government Leaders also tried to cover up the atomic bombing of Hiroshima; the bombing of Nagasaki was necessary in order to cause Japan to believe in the possibility of multiple nuclear weapons and therefore surrender. Cities and Civilians Spared: In addition, an invasion of Japan means more destruction of cities (the U.S. planned to crush all cities until they besiege Tokyo). More destruction and more time it would take for Japan to recover. Atomic bombings saved conventional warfare, saving lives on all sides: Millions of less Japanese casualties, less destruction of the Japanese cities, industry, and economy, Hundreds of thousands of less U.S. casualties, possibly millions of less casualties in Korea and Formosa (Thailand), and less human rights violations in Japan.

According to the Japanese Ministry of Internal Affairs and Communications, the population in Japan in October 1940 was estimated to be 73,114,308; in November 1945 the population was estimated at 71,998,104. Japan was visibly a thriving country that was hit very hard by the bombing.

The US Army Air Force dropped atomic bombs on the two Japanese cities, as ordered by then-President of the US, Harry S. Truman. During the final stages of World War II in 1945, the US conducted two atomic bombings against Japan, on the cities of Hiroshima and Nagasaki. The bombs were built in the …US with plutonium and uranium from mines in the Congo in Africa. The top-secret effort to build the bombs was the Manhattan Project. "Little Boy" was the codename of the atomic bomb dropped on Hiroshima, on August 6, 1945. It was dropped from the "Enola Gay", a B-29 Superfortress bomber which was piloted by Colonel Paul Tibbets ( retired as a General ) of the 393rd Bombardment Squadron, Heavy, 509th Composite Group of the United States Army Air Forces. "Fat Man" is the codename for the atomic bomb that was detonated over Nagasaki, Japan, on August 9, 1945, and was dropped from "Bockscar", another B-29 Superfortress bomber, this time piloted by Major Charles Sweeney, also of the 393d Bombardment Squadron, Heavy, 509th Composite Group. The "Enola Gay" was named for Colonel Tibbets' mother, Enola Gay Tibbets. "Bockscar" is a pun, based on the word "boxcar", the aircraft being named after Captain Frederick C. Bock, aircraft commander of "Bockscar" (the pilot is not the same as the aircraft commander). ( Full Answer )

At the end of World War II, few questioned Truman's decision to drop the atomic bombs on Hiroshima and Nagasaki. Most Americans accepted the obvious reasoning: the atomic bombings brought the war to a more timely end. They did not have a problem with over one hundred thousand of the enemy being kill…ed. After all, the Japanese attacked America, and not the other way around. In later years, however, many have begun to question the conventional wisdom of "Truman was saving lives," putting forth theories of their own. However, when one examines the issue with great attention to the results of the atomic bombings and compares these results with possible alternatives to using said bombs, the line between truth and fiction begins to clear. Truman's decision to use the atomic bomb on Japan was for the purpose of saving lives and ending the war quickly in order to prevent a disastrous land invasion. ( Full Answer )
By executive order of President Harry S. Truman the U.S. dropped the nuclear weapon "Little Boy" on the city of Hiroshima on Monday, August 6, 1945, followed by the detonation of "Fat Man" over Nagasaki on August 9. These are the only attacks with nuclear weapons in the history of warfare.
According to the Japanese Ministry of Internal Affairs and Communications, the population in Japan in October 1940 was estimated to be 73,114,308; in November 1945 the population was estimated at 71,998,104. Japan was visibly a thriving country that was hit very hard by the bombing.
The alternative to the atomic bombings of Hiroshima and Nagasaki was Operation Downfall, which was basically a D-day like invasion by the United States on Japan. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in October 1945, Operation Olympic was intended to c…apture the southern third of the southernmost main Japanese island, Kyushu, with Okinawa to be used as a staging area. Later, in spring 1946, Operation Coronet was the planned invasion of Kanto. In layman's terms, the alternative was to invade Japan from the south, using recently captured islands as airfields. Casualties range heavily, but most contend that American casualties range from around 200,000~300,000 while Japanese Casualties range in the millions. For example, In a study done by the Joint Chiefs of Staff in April, the figures of 7.45 casualties/1,000 man-days and 1.78 fatalities/1,000 man-days were developed. This implied that a 90-day Olympic campaign would cost 456,000 casualties, including 109,000 dead or missing. If Coronet took another 90 days, the combined cost would be 1,200,000 casualties, with 267,000 fatalities. *NOTE: the Olympic campaign and Coronet campaign are all part of Operation Downfall. In addition, the U.S. also considered using chemical weapons, but that was probably a worst case scenario (likely not going to happen) ( Full Answer )
Most likely 160,000 in Hiroshima and 80,000 in Nagasaki. But do not forget people died afterwards due to cancer.

the war was growing very violent very fast, so America decided to use it's most powerful weapon then, the atomic bomb. it wasn't dropped on factories because it wasn't dropped to hurt, it was dropped to scare.
There were a number of reasons these two cities made the list of targets for the atomic strikes. They were militarily important, possessed large, densely populated built-up areas, and were located on relatively flat terrain, among other things. And paradoxically, neither city had yet been subjected …to heavy bombing; the planners favored relatively undamaged areas so as to enable the effects of the bombs to be more apparent and measurable. Nagasaki was actually second on the list for August 9; bad weather and smoke over the primary target caused the planes to divert to Nagasaki, which was second on the list. ( Full Answer )
Some person were against the use of the atomic bombs mostly because of the civilan casualties the illness it brought and the devastation.
they were chosen because they were cities. but since they weren't super crowded or to close to American troops, it made them the perfect targets. even though they had children women and men that were innocent, it was better than bombing Tokyo or an even more crowded area.
USA! The plane used was call the Enola Gay. I think it was named after the pilot's mama!
Japan was going to loose the war anyway but I understand the need to send them a message of supremasy. President Truman stated that these weapons will end the war and save lives.
The Fat Man and the Little Boy (the names of the atomic bombs) were dropped on Hiroshima and Nagasaki to prevent a huge loss of life in the Invasion of Japan by America.
In the late 1930s the famous Physicist Eisenhower was notified by other German Physicists the Nazis were planning to build an atom bomb. He sent a letter to President Franklin Delano Roosevelt. Roosevelt had a committee formed to determine the necessity of the US building an atom bomb and do a feasi…bility study if it was possible to build the atom bomb. It had never been done by any country in the world. Meanwhile, the Japanese and the German scientists were doing the same thing. Eventually all three countries started their own programs to create atom bombs. The Germans ended up not building any atomic bombs even though they had the knowledge and people who could build an atomic bomb. They had told Hitler it was too expansive and could not be done quick enough to win the war. He fell for it. BUT the Germans supplied uranium for the Japanese scientists who were working on the bomb. Some of this uranium was captured by the Americans at the end of the European side of the war. So they used some of Japan's uranium on the Japanese: this is known as the irony of the atomic bomb. Therefore the atomic bomb intended for Germany came to be used on Japan instead when the Allied Forces were forced to consider a way to avoid the invasion and fighting on the mainland island of Japan. Truman made the final decision to drop the atom bomb in the Japanese Military leaders would surrender. Avoiding the possibility of millions of Japanese deaths and allied deaths was the number one motivation for using the atomic bomb on Japan. For the entire story of the development and history of the first atomic bombs see the related link below. ( Full Answer )

That's a very good question, this bombing was just a single bomb, not 300,000,000! The U.S hoped that the Japanese would be so horrified by the blast of the bomb that they would think that the U.S would bring all of Japan to the ground. This was not the only problem for the Japanese; the U.S forces …based at Okinawa were already preparing to invade Japanese soil. Just two days after the Japanese surrendered. It was so close some U.S ships were already along the coast shelling the land. Anyway, the Japanese were so terrified that they surrendered. ( Full Answer )
The bomb dropped on Hiroshima was August 6, 1945 The bombing at Nagasaki was on August 9, 1945, or 3 days after Hiroshima
While both the Hiroshima and Nagasaki atom bombs produced explosions via atomic fission, they were designed to do it differently. The first bomb dropped was "Little Boy", which was dropped on Hiroshima on August 6, 1945. This bomb derived its explosive power from the nuclear fission of 235 U (urani…um 235). The design used chemical explosives to shoot one piece of 235 U into another cylinder shaped target piece to create a super-critical mass, initiating a nuclear chain reaction. The second bomb, "Fat Man" was dropped on Nagasaki August 9, 1945. Instead of using the gun method to force pieces of uranium together, Fat Man used a shell of explosives around a spherical plutonium core to compress it to super-critical mass and initiate the chain reaction. The plutonium was produced in special reactors where purified uranium, consisting mostly of 238 U was bombarded with radiation to convert the 238 U to 239 Pu (Plutonium-239). ( Full Answer )
It was a big decision. President Truman stated that he needed to end the war and collapse Japan's means to make war ever again.
Little boy was the one dropped over Hiroshima and Fat man was the one dropped over Nagasaki.
