Another matter: I am disappointed that there have been so many strikes in these wars but the number of deaths have not been as high. I would not like to fire a bomb if it does not kill at least 50 people.
I think you have it backwards; More people are killed per bomb now than was the case in the past.
During the Blitz in WWII, the British government estimated that there were about 50 casualties, of whom about a third were killed and the rest injured, per
ton of bombs dropped by the Luftwaffe.
That roughly translates to 15 bombs dropped per death.
