Question

The U.S. did not want to invade Japan because they:

did not have means to transport soldiers from the U.S. to Japan.
wanted to focus on the war in Europe.
feared it would lead to a significant loss of life for U.S. military personnel.
did not think they could win a battle on Japanese soil.

Answer 1

I believe it was the third option if I recall. Because the American military didn’t want to have any unnecessary casualties occur.
