Some historians claim that it wasn't the bombs that made Japan surrender, but what they were facing if they didn't surrender. they were facing a mainland invasion from the US from the South and Russian invasion from the West. This is all assuming the US only had two bombs. I read somewhere we had a third one. Just something to chew on.
two bombs...you have to remember that the exodus of jews (look jillian you know i dont mean to be insulting but jews is just what is the easier to type) from germany brought some of the greatest minds in history with it....the bomb was planned....debated what the hell would happen....then built....the delivery of the bomb itself was ingenious....drop and head up as fast as you could.....cause they didnt expect to live so it was a what the fuck moment for the men of the plane ..they were told they most likely would not live..
now a link for you to look at:
Just before the First World War two German scientists, James Franck and Gustav Hertz carried out experiments where they bombarded mercury atoms with electrons and traced the energy changes that resulted from the collisions. Their experiments helped to substantiate they theory put forward by Nils Bohr that an atom can absorb internal energy only in precise and definite amounts.
In 1921 two Otto Hahn and Lise Meitner, discovered nuclear isomers. Over the next few years they devoted their time to researching the application of radioactive methods to chemical problems.
In the 1930s they became interested in the research being carried out by Enrico Fermi and Emilio Segre at the University of Rome. This included experiments where elements such as uranium were bombarded with neutrons. By 1935 the two men had discovered slow neutrons, which have properties important to the operation of nuclear reactors.
Otto Hahn and Lise Meitner were now joined by Fritz Strassmann and discovered that uranium nuclei split when bombarded with neutrons. In 1938 Meitner, like other Jews in Nazi Germany, was dismissed from her university post. She moved to Sweden and later that year she wrote a paper on nuclear fission with her nephew, Otto Frisch, where they argued that by splitting the atom it was possible to use a few pounds of uranium to create the explosive and destructive power of many thousands of pounds of dynamite.

a wee bit more
On 2nd August, 1939, three Jewish scientists who had fled to the United States from Europe, Albert Einstein, Leo Szilard and Eugene Wigner, wrote a joint letter to President Franklin D. Roosevelt, about the developments that had been taking place in nuclear physics. They warned Roosevelt that scientists in Germany were working on the possibility of using uranium to produce nuclear weapons.
Roosevelt responded by setting up a scientific advisory committee to investigate the matter. He also had talks with the British government about ways of sabotaging the German efforts to produce nuclear weapons
now for your confusion in the number of bombs...the us had 3.....one used to test with.....two dropped on japan....was it ethical...well hell yea....and you must remember truman was vp under most of this and then gets the call up to president right when there could be no hesitation....as assault on the mainland of japan would have costs unknonw numbers of american and allied lives...there was no doubt it would take something of major power to diswayed the emeperior who believe he was god like...you must look at this in the social context of the times....look at the history of the tinman..see the major battles and minor ones that decide the pacific ....look at the history of the kamikaze bombers ....the us would have lost thousands of men....
then look at the character of harry s truman...and you will see...he had no other choice...he would have accepted the "unconditional surrender of japan" at any time..prior to the fat boy and pior to the little boy...
do people just not have any damned concept of what ww2 was.....its not the glam and glory of the history channnel
