Hiroshima/Nagasaki vs conventional B-17 bombing

To put this in perspective, think of the bombs as hailstones. If I
have a hailstorm for 30 minutes with pea sized hail over, say a 2 acre
area and that hail had the equivalent water to 1/8 inch of rain, it
would cause a great deal of damage. But imagine the damage if there
were just one hailstone that weight 7000 lbs dropping from the sky.
Not nearly as much damage in most of the area, but where it hit, wow!


That's not a good reason either because why does it matter how
much damage is caused PAST the point where everything is
destroyed?...everything past that point is useless overkill...
