For the WWII buffs

I have been wondering lately why the USA droped the atomic bomb on the residents of the two Japaneese citys. It seems that the scientists at the time were in favor of not dropping it while the political leaders at the time, Truman and Jimmy Byrns were for droping it, more in a poltical stand point to prove something to Russia? Am I correct on this or am I missing something. I feel like it was more of a terrorist attack than really accomplishing anything. The Japs were ready to surrender as Russia entered the war.
