The two options for the United States to win the war were to continue the naval blockade and invade the mainland, or to drop the new, highly destructive atomic bombs. In the long run, the naval blockade would have deteriorated the entire country by starving the citizens, killing hundreds of thousands if not millions. Along with all of the civilian lives lost in the blockade, the amount of troops lost would be even more unimaginable. According to a very credible textbook, The Decision to Drop the Bomb, which is used to educate young adults on the bombings of Hiroshima and Nagasaki, "Japan had an army of 2 million strong stationed in the home islands guarding against invasion." This huge army would have withstood a Normandy-type amphibious landing on the beaches of Japan that "might be expected to cost over a million casualties to American forces alone" (Walker 2). President Truman, the President of the United States at the time, knew both of these facts and picked the easier, more life-conservative approach of using the atomic bombs. By using the atomic bombs, Truman "saved 'the lives of hundreds of thousands of Japanese boys and millions more of Japanese people" (Walker 4), not to mention all the lives of American men who had not seen their families since the first gunshot fired of the second world war. Even after the Americans preserved countless lives by avoiding an invasion of Japan, many Japanese officers and soldiers still wanted to continue fighting the war in the Pacific. The Japanese were willing to fight to the last man despite having lost hundreds of thousands to conventional firebombing. The only way for the United States to get an unconditional surrender, a surrender in which no guarantees are given to the surrendering party, was to drop the atomic bombs. .
Japan was struck hard by the war, which pushed the nation to the verge of collapse even without the bombs.
