Have to smile at those who believe that at Hiroshima, we crossed some sort of irreversible moral threshold. That threshold had been crossed long before. If you believe it is morally acceptable to kill a whole lot of innocent civilians by dropping a whole lot of bombs on them, then clearly it is morally acceptable to kill a whole lot of innocent civilians by dropping one megabomb on them.
Which is worst; to starve to death 85,000 soldiers in a Death March and it's aftermath of years in prison or bomb and wipe out that same number in an instant ?
When people are willing to agree that BOTH are vile and awful things to happen to mankind from governmental decisions, then we have a hope of peace.
But then you have to move over to various 'religions' in the World next.
When you 'fix' religious wars, then we can look at one man dictatorships and the citizens that facilitate and allow that person to control their lives.
Wake me when that happens. I'll be with Ted Williams....
