No, you're just some dickless bigmouth on the internet. Real American military leaders understand war and life and death.
"Admiral William "Bull" Halsey, the tough and outspoken commander of the U.S. Third Fleet, which participated in the American offensive against the Japanese home islands in the final months of the war, publicly stated in 1946 that "the first atomic bomb was an unnecessary experiment." The Japanese, he noted, had "put out a lot of peace feelers through Russia long before" the bomb was used."
But all those "Peace feelers" were contingent on Japan keeping the territories they had seized and not holding the war criminals to account.
One more time. Everyone had second thoughts about the bomb after the war, when the true potential of atomic weaponry was realized. In many ways, guys like Halsey and Patton realized the A-bomb put them out of jobs. Fleets and Armies became kind of meaningless when you can just erase whole countries from the map.
At the time it was used, it was just another weapon. 60,000 dead at Hiroshima might SEEM bad, until you realize 70,000,000 died in the war, and Hiroshima represented less than 0.1% of the deaths in WWII. Dragging the war on for another month while "peace feelers" were explored would have resulted in more deaths than the bombing did.
