How did the bombing of Hiroshima and Nagasaki affect the American involvement in the war and how did it affect the outcome of the war?? Also, what are the who, what, when and why about the bombing of Hiroshima and Nagasaki?

Well the dropping of the atom bombs took place after the war was already over. Japan admitted defeat, but word didn't get to the general in charge of the bombing until it was too late, and thus Japan was hit. Because of this, you can technically say that it didn't affect anything seeing as the war was technically already over.
