The use of these bombs brought a quick end to World War 2, yet caused extensive damage to the two Japanese cities. There have often been disputes as to whether the USA was justified in the dropping of the atomic bombs because of the damage they caused, not only to the cities, but to the people of Japan as well. Many people believe that the USA should not have dropped the bombs because of the damage they caused, and they also claim that Japan was already defeated. However, Japan did not surrender, and prolonging the war was not an option for America, as it believed it would cause even more casualties, not only to American troops, but to Japan as well. Thus the USA was justified in dropping the bombs on Japan.
