This propaganda promotes the atomic bomb, using the attack on Pearl Harbor to convince the public.
The U.S is giving off the feeling to the people that the Atomic Bomb is safe for the U.S and it offers protection for it's citizens through this propaganda poster.
Americans were overjoyed that the war was over after the atomic bomb. Many American lives were saved from the bomb.
Even though they lost the war, thousands of Japanese lives were saved by the bomb because the soldiers didn't go to battle.
The Japanese if we did not stop them would have captured and killed more of the American soldiers. The U.S didn't want to send more troops in to handle the situation fearing more people would have been either captured or killed. This propaganda poster presents that situation to the public eye.
The Japanese had captured American people and killed them. The Japanese would not surrender , and kept fighting. This is one of the reasons why the U.S dropped the bomb. They wanted to not waste troops on invading again which would result in more deaths for both sides.
