If atomic bombs are to be added as new weapons to the arsenals of a warring world, or to the arsenals of nations preparing for war, then the time will come when mankind will curse the names of Los Alamos and of Hiroshima.

Dropping those atomic bombs on Hiroshima and Nagasaki was a war crime.

Doctor Atomic

The atomic bomb made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass; and beyond there is a different country.

Thou art my battle axe and weapons of war: for with thee will I break in pieces the nations, and with thee will I destroy kingdoms; / And with thee will I break in pieces the horse and his rider; and with thee will I break in pieces the chariot and his rider; / With thee also will I break in pieces man and woman; and with thee will I break in pieces old and young; and with thee will I break in pieces the young man and the maid; / I will also break in pieces with thee the shepherd and his flock; and with thee will I break in pieces the husbandman and his yoke of oxen; and with thee will I break in pieces captains and rulers.

Hiroshima and Nagasaki were atomized at a time when the Japanese were suing desperately for peace.
