Really? You really see no compelling evidence that the U.S. would have had to invade Japan to end World War II, if not for dropping the atomic bombs?
Please elaborate. I’m not sure I follow your reasoning, but would like to consider your point of view. I see what you are saying about assumptions of two options available to end the war, but just don’t see offhand what other options were available to us at the time. Please explain.
It's August 2nd of 1945. What facts in place at the time (and I'll give a wide degree of latitude here to include anything from a well-documented historical record as a "fact") made it absolutely imperative for the U.S. to drop atomic bombs on Japanese cities at that point in time?
An analysis based on the presumption that "I must do X to you because the only alternative I have is to accept Y" is a poor line of thought here in a military conflict at that particular juncture.
