Japanese would not quit, wanted to fight to the death including kamikazes
Japan was ready to call it quits. home islands were being blocked so they couldn’t get anything
Invasion of Japan would have caused more casualties than the death toll at Hiroshima & Nagasaki
Casulaties due to invasion would have mostly been military and not civilian
Japan was warned to surrender or face destruction and did not
Japan would surrender with right terms, one bomb could have been used in Tokyo Harbor as a demo
