On August 6, 1945, U.S. President Harry Truman informed the world that an atomic weapon had been detonated on the Japanese city of Hiroshima. Nicknamed Little Boy, the bomb with a power of over 20,000 tons of TNT destroyed most of Hiroshima, killing an estimated 130,000 people. Three days later on August 9, a second bomb nicknamed Fat Man was dropped on the Japanese city of Nagasaki destroying most of Nagasaki and killing roughly between 60,000 - 70,000 people. Six days after the bombing of Nagasaki, Japan surrendered, marking the end of World War II.

The destructive power of these nuclear weapons and the subsequent casualties of the Japanese have continued to prompt questions over whether the U.S. should have decided to use these deadly weapons against Japan during World War 2 even though many alternatives were available.

Certainly, the power of this new weapon was understood before its use against Japan. President Truman stated that “it was the most terrible thing ever discovered.” To that end, the decision to use this new weapon was not taken lightly, nor was it made in a vacuum devoid of dissent, despite what historical accounts may depict. Specifically, historian J. Samuel Walker purports that history has painted a false dichotomy which posited that Truman had to choose between using the atomic bomb and risking hundreds of thousands of American lives. Instead, as Walker highlights in his book “Prompt and Utter Destruction,” the historical records show a much more complex situation.

To be sure, as the development of the atomic bomb was nearing its completion, the U.S. was still engaged in a massive war with the Japanese. By all accounts, from the middle of 1944, it was clear to both the Japanese and the United States that the Japanese were losing the war and that the question was when Japanese would finally capitulate. As the summer of 1945 began, the U.S. military campaign continued to involve numerous aerial raids as well as large scale invasion of Japanese islands. Accordingly, before the atomic bomb became available, the U.S. was planning another large scale invasion of Japan codenamed Operation Downfall for the fall of 1945, which it hoped would overwhelm the Japanese and end the war.


Deciding to Drop the Bomb

The six reasons why Truman chose to use the bomb.

Ending the war at the earliest possible moment -The primary objective for the U.S. was to win the war at the lowest possible cost. Specifically, Truman was looking for the most effective way to end the war quickly, not for a way to not use the bomb.


To justify the cost of the Manhattan Project-The Manhattan Project was a secret program to which the U.S. had funneled an estimated $1,889,604,000(in 1945 dollars) through December 31, 1945.


Use of the bomb was more to scare Russia than to defeat Japan.-With the end of the war nearing, the Soviets were an important strategic consideration, especially with their military control over most of Eastern Europe. As Yale Professor Gaddis Smith has noted,“It has been demonstrated that the decision to bomb Japan was centrally connected to Truman's confrontational approach to the Soviet Union.” However, this idea is thought to be more appropriately understood as an ancillary benefit of dropping the bomb and not so much its sole purpose.


A lack of incentives not to use the bomb -Weapons were created to be used. By 1945, the bombing of civilians was already an established practice. In fact, the earlier U.S. firebombing campaign of Japan, which began in 1944,killed an estimated 315,922 Japanese, a greater number than the estimated deaths attributed to the atomic bombing of Hiroshima and Nagasaki. The firebombing of Tokyo alone resulted in roughly 100,000 Japanese killed.

Racially Motivated
Racism played an important role in the decision in President Truman’s decision to use the atomic bomb ; that had the bomb been ready in time it never would have been used against Germany. All of America’s enemies were stereotyped and caricatured in home front propaganda, but there was a clear difference in the nature of that propaganda were anti-Japanese racism in American society targeted the Japanese as a race of people, and demonstrated a level of hatred comparable with Nazi anti-Jewish propaganda.

To justify the cost of the Manhattan Project-The Manhattan Project was a secret program to which the U.S. had funneled an estimated $1,889,604,000(in 1945 dollars) through December 31, 1945.

Alternatives to dropping the bomb

1. Intensifying conventional bombing and the naval blockade- General MacArthur felt that air power alone could force a Japanese surrender within six months with little risk to American lives. However, it was also argued that this may be a best case scenario where in actuality it could take substantially longer.


2. Allowing the Japanese to retain their Emperor
The second and perhaps most important alternative to both the bomb and the land invasion was to modify the demand for unconditional surrender and allow the Japanese to keep their emperor. Of course, he would have to be demoted to a powerless figurehead, but it was possible that this one condition alone might have been enough to satisfy the American War Department’s conclusion that it was necessary to convince the Japanese that they would not be “annihilated” if they surrendered. The American government clearly understood that if they harmed the emperor, whom the Japanese revered as a god, the Japanese would resist forever. And the key to this argument lies in the fact that the American government already planned on letting the emperor stay. All they had to do was find a way to hint their intentions loud enough for the Japanese to hear.

3. Waiting for the Soviets
American President, and at least some Japanese all were of a mind that a Soviet intervention in the war would prove decisive. And, a date for this intervention had been set. So why the United States used atomic bombs on August 6 and 9, when they knew the Russians were coming a week later, and when Operation Torch wasn't scheduled for months. Why not wait?

4. A Demonstration of the bomb

One alternative might have been to arrange a demonstration of the bomb. Although the U.S. and Japan had no diplomatic relations after Pearl Harbor, a demonstration might have been arranged discretely through some back channel, perhaps through the Russians.

In the end, none of these alternatives were chosen.

Conclusions

The purpose of this article is not to give arguments against the use of Atomic Bomb but is instead intended to highlight the complexities of the situation.It is clear that there were multiple reasons for using the atomic bomb, but that at the same time there were also alternatives which may have proved equally effective in prompting a Japanese surrender.
One could argue that by just modifying unconditional surrender, the U.S. could have saved both U.S. lives and the lives of those Japanese residing in Hiroshima and Nagasaki. Or, as Walker noted, it seems reasonable to conclude that “a combination of B-29 raids with conventional bombs, the blockade, the Soviet invasion, and perhaps a moderation of unconditional surrender policy would have ended the war without an invasion and without the use of atomic bombs.”

simple because trueman didnt wanted the war to continue for two more years by killing 500,000 he saved 15 million on both sides
That's just a convenient argument made by Americans to justify their military bravado. Saving 15 million lives by using Atomic bombs is a wierdly exaggerated statement. We are hearing this age old argument of aggressors justifying killing with the saving of lives relative to what would have been lost had the killing not taken place.
If the US wanted to end the war with minimum casualties, they could have done it by demonstrating a low yield atomic bomb's capability at a relatively uninhibited area.
 
The US wanted to show the world the US could have conquered and united the whole world under 1 country in 1945 but chose not to do so out of stupidity :rofl:
 
Because they falls in Asia:coffee:
Actually the American was quite vocal about it. They themselves said that they never would have done it against Germans even if Hitler was winning the war.
America population during 1940's were bit racist, they even made racially stereotyping poems in the 40's to justify their propaganda against Japanese.

Just see the poem "Remember Pearl Harbor” by Carson Robison

"Remember how we used to call them our "little brown brothers?"
What a laugh that turned out to be
Well, we can all thank God that we're not related
To that yellow scum of the sea
They talked of peace, and of friendship
We found out just what all that talk was worth
All right, they've asked for it, and now they're going to get it
We'll blow every one of them right off of the face of the Earth "

Now you can know why they don't want Asia to rise and unite.

On Topic: US wanted to show its power by using A-bomb to USSR which they knew is new rising power and will challenge them, and it worked for some time till USSR developed the A-Bomb.

American also wanted to show who was the boss in the Asia pacific. So they were more than happy to show it by using the jewel of their technological prowess Atom bombs.
Some Americans at time has openly said that Soviets can be contained if impressed by American military might, and that a demonstration of the atomic bomb on Japan might impress the Soviets.
 
@Lord Aizen ,

By April 12, 1945, the Japanese were at communication with the Russians on how to initiate the surrender to the Allies. The Russians knew of Japan's intention to surrender, for reasons unbeknownst to us, the Russians had plans in Sakhalin, Manchuria as well as Korea, and thus kept our communique silent to the Western Allies. In my opinion, surrender was inevetible, by the time the bombs were dropped, Japan had been exhausted by war, a war that began in 1931. It was a failure on Government's part to realize the futility of continuing the conflict past 1944. The atom bombs and hundreds of thousands of lives could have been spared had Tokyo acquiesced to ceasure of hostilities by 1944. Poor decision making plagued the Imperial Government -- from the decision in not punishing the junior officers in the Kwangtung Army for their role in the Mukden Incident (arguably the catalyst to the 2nd Sino Japanese War) to--- the end.

Japan was indeed fighting a losing war which become clear after battle of Okinawa & other battles fought on Japanese Islands & Japanese imperial government are to be partially blamed for pushing Americans to make the deadly Nuclear attacks. But Americans were really adamant & were making unreasonable demands. They were not clearly diplomatic in their approach as they had been with west European powers.
I somewhere read that before Hiroshima attacks Emperor Hirohito was ready for a "conditional surrender" which the Americans never took seriously & when the Soviet Union suddenly declared war on Aug. 8, the day before the Nagasaki Atomic bomb was dropped,Emperor Hirohito put pressure on the military government to immediately surrender unconditionally. But the Americans never heeded it & dropped the bomb again. At least they could have stopped with Hiroshima & avoided the Nagasaki nuclear attacks

Truly , it was a shameful moment in our history.
 
@Nihonjin1051 If the emperor had announced an unconditional surrender after the battle of Okinawa...would the imperial army have accepted it or there would be still objection to it???

They would have listened to him. It's a pity His Majesty did not intervene sooner.

I should add that the Army would have listened, but there were fanatics in the Imperial Privy Council that would have opposed. In fact, some of them would preferred the Emperor dead than do anything contrary to their plans.
 
The letter by Einstein to FDR warning of Germany's possible Atom bomb research was in 1939. Japan wasn't even on the radar when the ball started rolling.

Anybody who thinks Germany would never have been attacked by an Atomic weapon should go look at pictures of bombed out cities in Europe during WW2.

So the privy council represented the more nationalist elements in Japan !
but considering there was a failed coup attempt even after the events in Hiroshima and Nagasaki to stop the unconditional surrender the emperor had some valid apprehensions about intervening that early !
