I suppose we could have starved the Japanese to death but that would have taken a long time and been incredibly cruel.
Perhaps we could have set up a blockade around Japan, but starving them to death would have been cruel, you are right.
I hope Alberta’s Child will elaborate on how we could have ended the war without the A-bomb and without a conventional invasion of Japan.
My Uncle married a Japanese woman. Her brother was one of the best people I have ever known. Their father didn’t make it back to Tokyo until the end of 1946, he was a POW in Russian controlled territory (N.Korea, I think). As such, it was the son’s job, as the oldest boy (11 years old), to bring food home, to the starving family. He learned very quickly to find a military encampment, bring a pot, do menial chores (shoe shines, etc.), and then return home with leftover food. I remember him saying “One thing was for sure, in those uncertain times; G.I.s are gonna be fed, three times a day”.
But then that would have been their responsibility, not ours -- right?
We already had battleships offshore shelling factories before we dropped the bomb.
Furthermore, most of the starvation would have been inflicted upon peasants and civilians, not upon the military and political rulers of Japan.
