The Dropping of the Atomic Bomb

Today we will consider what reasons the U.S. had to implement the use of the atomic bomb at the end of the Manhattan project. The Manhattan project began in 1939 and the war ended in August 14, 1945. The U.S. first tested the bomb July 16, 1945, which gave them roughly a month to determine whether or not it was beneficial or ditrumental to ending the war. From this, it is left up to the individual to decide. One may consider that Japan was already weakened without help from the withdrawing Germany. From this, one can deduce that although it would have cost more American lives, thousands would have been saved should the U.S. have decided to wait 'till Japan ran out of resources and moral.

So, was the dropping of the atomic bomb in Hiroshima and Nagasaki necessary?
