It had to be done and President Truman made the right decision. Why should one more American Sailor, Soldier, Marine or Airman die when we had such a weapon available? And there were still millions of Japanese soldiers in the field around Asia. How many Americans and how ten-times many more Japanese would have died in an invasion of the Home Islands?
All the armchair quarterbacking in hindsight is worthless and offered by individuals who ‘never had their b*lls on the anvil’ as Paul Tibbetts said.
My bet those who object did not have relatives in the landing army.
My Dad was in Hiroshima 6 weeks after they dropped the bomb. He said if Truman hadn’t made that decision he probably wouldn’t have come back because they would have lost at least a half a million guys storming those Japanese beaches.
