Historians do have different opinions as to why the USA dropped two Atom bombs on Japan. Russia did make a push on Japan just before the first bomb was dropped. So there was support from allied troops. So why didn't the USA just land and make it's way to the capitol? My opinion is this, the USA dropped the bombs because they ran out of money to support the war. It was the most cost effective way to do it as a lengthy ground campaign was too taxing. Two bombs was more feasible then more American lives. Does anyone else have different opinions on the matter?
