NEW DELHI -- History is written by victors and thus abounds in well-cultivated rationalizations for the winners' actions, however unjustifiable or gory they might be. Vanquishers are rarely burdened by guilt. Sometimes the rationalization stops with their first major slaughter in a war, as if their willful repeat of similar blood baths were automatically defensible.

This is best illustrated by the United States' atomic bombings of Hiroshima and Nagasaki. If the incineration of Hiroshima was justifiable as a means to end the war and save American lives -- a thesis that even most liberal Americans accept -- what was the justification for the destruction of Nagasaki three days later before Japan had a chance to grasp the message from the first nuclear attack?

The U.S. actions arose not from any rage but from cool, calculated thinking. The intent was to deliver a crippling psychological blow to Japan by obliterating two of its important cities. No warning was given to the residents of Hiroshima and Nagasaki before unleashing the nuclear holocaust.
