My Dad was in the Army at the time, and most likely would have taken part in an invasion of Japan had we not dropped the bomb and forced their surrender. It is very possible that I am here today because of what happened in Hiroshima and Nagasaki.
My dad had his orders cut to proceed to the Pacific theater . . . that's bad enough . . . but my father in law had HIS orders cut for the invasion of mainland Japan! He was Signal Corps at that time (later Army Air Corps and Air Force . . . retired as a bird colonel) and had already been thoroughly shot at on Iwo and Saipan, had his jeep blown out from under him on Iwo without so much as a scratch sustained. But I think his luck would have run out in a mainland invasion . . .
As are millions of other Americans,Japanese and probably other nationalities as well.
Me, too. My Dad was in Navy language school learning Japanese when the war ended. He ended up using what he learned to become a missionary to Japan in the post-war years (where he met my Mom).
