What three actions did the allies take to force japan to surrender before resorting to the use of the atomic bomb?

Explanation:

Before the atomic bomb was used in Japan, the Allies took several actions in order to force Japan to surrender. Widespread bombing was one, as the Allies bombed more than 60 Japanese cities. The Soviet Union also declared an attack on Japan. Finally, the Allies issued the Potsdam Declaration. This ultimatum stated that if Japan did not surrender, it would face "prompt and utter destruction."
