Supporters of using the atomic bomb against japan at the end of world war ii thought an invasion would ?
a. cost too many american lives.
b. not be successful.
c. be opposed by the american people.
d. require the navy to build too many ships

The correct answer is A.

The most important claim of supporters of the atomic bomb was that, taking such an extreme measure would force the Japanese Empire to surrender. This would avoid an innecessary invation of the Japanese territory, which would lead to an incredible loss of American lives.

It was believed that the great amount of casualties would be caused by different reasons.

Firstly, because the Japanese had ordered to kill all Allies prisioners in case of an American invation. Secondly, because all the Japanese soldiers would be concentrated in the few good landing site, giving them the upper hand in battle. And thirdly, because Japanese were ready to fight till the death, since dying for their country, and even suicide, are considered honorable in their culture.
