A controversy sprang up almost immediately following the war and has been hotly debated by historians for over 60 years. Historians mainly debate the question of whether the bombs were necessary to end the war. Those who argued against the use of the bombs state that the bombs were militarily unnecessary. People supporting this argument believed that Japan would have surrendered eventually even without the use of the bombs. They believe that the Japanese government was gradually coming to the realization that Japan could not win the war. Japan is a country made up mostly of an archipelago, which is a collection of many different islands that are formed tectonically. Other historians, however, state that the bombs were necessary because of military intelligence at the time. Intelligence revealed that the government was arming civilians, and it was believed they would willingly defend their country. This belief was based on Japanese casualty rates in battles with Allied troops. Military strategists projected that Japanese civilians would also choose to fight rather than accept defeat. 1 Which sentence could be deleted from the second paragraph because it is irrelevant? A.
