To end WWII.
President Truman was told that if the U.S. invaded Japan, the number of American casualties could exceed a million. The Russians were preparing to invade Japan and Truman did not want what was happening in Eastern Europe to happen in Japan. Therefore, it felt it would be best to end the war as quickly as possible.

It was the other way around. Albert Einstein and another physicist influenced World War 2 when he wrote a letter to President Roosevelt telling him that the Germans were starting on an atom bomb. He suggested the US get an atom bomb made to stop the German Nazis. Roosevelt and his committee chose to follow Einstein's advice and the Manhattan Project was created as well as three atom bombs. However, Einstein disliked the thought of nuclear bombs being made and used. He knew the devastation it would cause. He also was leary of Humans using nuclear physics to create anything.
To save millions more lives that would have been spent in a drawn out conventional war with imperial Japan, the scientists in the United States (ahead of Nazi Germany, who was also working on the atomic bomb) created the bomb to escalate the war with Japan. They ignored the first bomb dropped on Hiroshima, but the Empire of Japan decided they could not win and surrendered to the US shortly after a second bomb was dropped on Nagasaki.
== == The final decision was made by the US President at that time, who was Mr Truman.
the reason was the Germans did not leave Poland so they had to declare war on Germany otherwise the Germans would attack us and take over us.
The US, working with the British, developed the atomic bomb, as it was then called, because it was believed that Nazi Germany was well on the way to making one and it was necessary to be able to match them if they began to use, or threatened to use, such a weapon. As it turned out, the Germans had not been able to overcome technical as well as political problems and were never near to construction of an atomic bomb. Germany surrendered before the American/British effort had been completed. The bomb, once developed, was used on Japan to bring the Pacific war to a sudden end. While there has been subsequent controversy about whether the bomb should have been used on Japan, at the time there were very few people who were aware of the bomb's existence and capabilities and who thought it ought not to be used. Most of those few thought that a demonstration on an unpopulated location should be made first.
Yes, because the Japanese wouldn't surrender for war
They dropped the atom bomb in nagsaki and hiroshima.
1945
who was the u.s afraid would get an a atom bomb first
for defense in war, kind of a last resort
1 reason was us want latest jet technology of germeny( nazi) 2 reason was us want defeat germany because he knows that germany work on atom bomb and if he make it he destroy all us after uk. 3 reason was that us want a new market for his weapons
1945
If you mean the US, yes.
the US originally began the project to make atom bombs to protect itself from the possibility that nazi germany might make them.
probably would have, but japan did NOT have the atomic bomb...........
Atom Bomb !! :)
Look up "The Manhattan Project"
