In the middle of war, the higher ups in the government and military like to think they have the knowledge of all aspects of what is going on in the world of war. This thinking might stand true with today's technology but during the war time of the Bombing of Japan this was not the case. Many military documents surfaced after the bombing showing that we, the United States of America, did not have to go to the extreme in making Japan surrender. Documents showing that we did not give them enough time to surrender with the demands set forth were shown that the United States had surely jumped the gun on doing such devastation to humanity all in the name of justifying the building of such an expensive bombs to the tune of two billion dollars. The United States also felt they needed to "prove" to the world that we are a powerful nation with the means to wipe out troubled nations if it came down to it. This war was the perfect opportunity to do this and have it be "justified". The code name for this bombing was called "The Manhattan Project" .
The United States concealed this project until after its completion of building and testing of this type of bomb, and atomic bomb. Tests conducted in the desert at an area they called Jornada del Muerto (Journey of the Dead) near New Mexico. These tests were conducted on July 16, 1945, not even a month before they were to be used on Japan. Though pleased with the results of what physical damage they could do to the landscape of Japan they did not really take into full consideration the human aspect of it would be. The dropping of the Hiroshima bomb would have been enough to make Japan surrender but the military also wanted to see which bomb would be more effective in the future so they dropped both types within days of each other.
On August 6th, 1945, during World War II, the United States dropped a massive, powerful and most deadly weapon the world had ever acknowledged, known as the Atomic bomb, on Hiroshima and Nagasaki.
