In his 2011 book Atomic Cover-Up, Greg Mitchell says, "If Hiroshima suggests how cheap life had become in the atomic age, Nagasaki shows that it could be judged to have no value whatsoever." Mitchell notes that the U.S. writer Dwight MacDonald cited in 1945 America's "decline to barbarism" for dropping "half-understood poisons" on a civilian population.
The New York Herald Tribune editorialized there was "no satisfaction in the thought that an American air crew had produced what must without doubt be the greatest simultaneous slaughter in the whole history of mankind."
Mitchell reports that the novelist Kurt Vonnegut, Jr. ? who experienced the firebombing of Dresden first hand and described it in Slaughterhouse Five ? said, "The most racist, nastiest act by this country, after human slavery, was the bombing of Nagasaki."
