There were several military arguments for using the atomic bomb against Japan in 1945. First, this would bring about an early surrender of Japan and avoid what would probably have been a prolonged struggle with much loss of life by US forces. Secondly, the USSR was already moving against Japan and had seized one small island (which Russia still has, even in 2013) and the US feared that Japan would become a Soviet satellite, much in the way that eastern Europe was. The Cold War began even before WW II was over. An early Japanese surrender avoided that problem.
Because it saved hundreds of thousands of American lives and Millions of Japanese lives by not having to invade mainland Japan
They dropped it because japan refused to make efforts to end the war peacefully, and would not give on fighting the war until the US controlled every Japanese island.
