Was using the atomic bombs very effective to finish the second world war and was it really necessary ?

Answer 1

I am going to go in a little different direction. The one fact that everyone seems to ignore is that the Soviet Union declared war on Japan after the first bomb. According to historical documents, the Japenese military was not that concerned about the atomic bomb. A city was destroyed, yes but cities had been destroyed with conventional bombing. As a matter of history, more people died in Tokyo from fire bombing than died at Hiroshima.

When the Soviet Union declared war, they had over two hundred divisions in Mongolia ready to invade the northern part of Japan. That is approximately 2.6 million men.

The Emperor decided to surrender to the US because if the war would have gone on with Russia on the North and the Americans in the South, Japan would have ceased to exist as a country, a people, a culture. That was their greatest fear.

Answer 2

Despite my strong dissatisfaction for the decision of "dropping the bomb", most signs point to "yes, it was really necessary".

(-) Japan was losing the war to the point of the islands of Japan being completely barracading, and since Japan has no resources of its own, Japan was almost useless.
(-) The permanent damage bestowed upon the people, leaving numerous ill and injured for the rest of their life, if they survived the blast, and leaving some of the lands in little or no use.

(+) If the war were to continue, hundreds of thousands of U.S. soldiers would have lost their lives, putting a huge damper on the families and economy of the U.S.
(+) It was later discovered that Japan was in research of the production of atomic bombs [research aided by Nazi scientists] that would have yielded atomic bombs ready for use on U.S. forces, bases, and possibly even mainland cities before the land invasion of Japan could be successful.
(+) The war had already been going on for years, leaving U.S. soldiers fatigued; the battle on Japan would have resulted in further fatigue on the soldiers, as well as the economy.
(+) With Russia [at the time, the communist Soviet Union] having been on the offensive again in the war now that Germany was out of the picture, it was imperative to show that the U.S. had aweful capabilities and that the U.S. was not one to mess with, especially considering that the Cold War was in play [the Cold War actually started at the end of World War I when the U.S. decided to invade Russia with Japan to put down the communist Soviets who were taking over the government, leaving the Russians to spite the U.S.; the U.S. spited Russia for having been communist]
(+) Japanese fight to the bone and seldom surrender, some Japanese soldiers who were separated from their platoon being found tens of years after the end of the war on Asian islands; the soldiers would still be firing at the "white man", thinking the war was still going on, which can be viewed as a psychological aspect to the Japanese and never giving up; the bomb would be strong persuasion for the Japanese to finally surrender.

So, despite the harm and seemingly unessentiality of dropping the bomb, the U.S. would have most likely been nuked after losing hundreds of thousands of troops on a long bloody battle on Japanese soil, also later having to deal with soviet Russia, who would have not been nearly as scared of the U.S. as the Cold War escalated in the 1950's.

"Yes", it was necessary, I suppose.

Answer 3

effective yes necessary mayb but it was ultimatly these 2 choices invade Japan or drop the bombs as bad as it sounds the bombs may have been the lesser of the 2 evils because if we invaded it could have taken months or over a year to conquer the islands of japan costing countless numbers of deaths its very possible that the invasion could have killed more people total the the bombs did but we will never know\

Answer 4

Effective? Ask Hirohito.

Necessary? That depends on how much longer you would have wanted the war to continue, and how many more people you would have wanted to die.

Answer 5

Effective yes
Necessary entirly

Explination:we used them we had one more they submited
IF we had invaded we would of lost three million american baby boomers what this translates into is one out of ten people you have met or know wouldnt be here right now.

Answer 6

yes and yes for many reasons,chief of which was to end the war and save the loss of further USA soldiers. to show japan that the usa had the will and means to destroy her utterly and leave no doubt that surrender was the only viable option.
