Though various standard bombing raids on Tokyo killed more people, the atomic bomb is debated on whether or not the bombing was necessary. Frequently, debates focus solely on the status of Japanese military in Japan. What one forgets is that Japan and its allies and puppets were still in control of a vast part of Asia. Imperial Japan, the Reorganized National Government of China, and Manchukuo all had standing fighting militaries. There were also puppet states that were large variables on whether or not they could offer opposition which would require further fighting outside of Japan. The fact that the Japanese's Greater East Asia Co-Prosperity Sphere wide span was a major factor in ending the war once and for all in a single stroke in Japan.
