Well.... The only GOOD thing to come out of the Atomic Bombs dropped on Japan was that it ended the war in the Pacific, and WWII as a whole.
After Germany surrendered on May 7th, 1945, the Japanese were frankly disgusted. They said that Germany should have fought to the last man and last bullet before laying down their arms. To the Japanese, to surrender willing was a cowardly disgrace, and was the reason for many of the kamikaze attacks on U.S. ships. It was also the reason why Japanese pilots carried pistols in their planes because if they were shot down and just so happened to survive, they needed to kill themselves instead of having the humiliation of being captured.
So, Japan made it very clear that unlike Germany, they would fight tooth and nail till the very end. At the time, the U.S. saw the Atomic Bomb as a cheaper alternative to losing men and equipment in a seemingly never-ending battle against the Japanese Empire.
