I believe you are underestimating what Japan did in the Pacific in the late 1930s and early 1940s.

Japan had pretty much taken over the entire South Pacific. They had attacked China, Russia, Philippines, Malaya, Burma, the Dutch East Indies, Singapore, and Rabaul... Then they attacked the United States and Australia.

The Japanese were both fanatical and brutal. They would refused to surrender no matter what, would fight to the last man, and the handful that survived would commit suicide instead of surrendering. In some of the island fighting, they would kill an American solider, chop off his penis, and shove it into his mouth.

The Japanese was fought all across the Pacific ocean and refused to surrender. The only way to get them to surrender was to bomb them into submission or invade. If we invaded, millions more people would have died.
