The United States was at war with Japan during WWII starting with the bombing of Pearl Harbor. The United States felt a continuous threat from Japan and took many steps, some necessary and some unnecessary, to protect our country from further attack. President Harry Truman had a difficult decision to make: invade and fight with Japan or use the most advanced weapon in the war against the growing army of the Japanese who were willing to stop at nothing to take America down.
Although many innocent people were killed and affected by the bombings, invasion was estimated to be more devastating to both Americans and Japanese and took major part in ending the war; because of Japan's reluctance to cease war with the United States, Truman took all efforts to protect our country's people no matter the cost.
