The use of the atomic bomb, with its indiscriminate killing of women and children, revolts my soul.

Hoover’s statement frames the atomic bomb primarily as a moral problem rather than a strategic one. By emphasizing “indiscriminate killing,” he invokes a long-standing ethical distinction between combatants and noncombatants, arguing that a weapon whose effects cannot be confined to military targets violates basic humanitarian restraints. The phrase “revolts my soul” signals visceral, conscience-level condemnation—suggesting that even in total war, some means are unacceptable. Read in the broader post–World War II debate, the quote aligns with early anxieties about nuclear warfare’s scale and its erosion of traditional limits on violence, anticipating later arguments about nuclear weapons as inherently indiscriminate and thus morally illegitimate.
