The bombing of Hiroshima was necessary, but it was also a necessary evil. It is good that there are mixed opinions about it. America would be a poorer nation if Hiroshima and Nagasaki were universally lauded as noble and heroic acts.

And I think you'll find that if America finds itself having to nuke another city, they'll have no trouble finding people who will do it. The 20th century shows that when it comes to attacking civilians with bombs or missiles, most military men do so without hesitation or regret.
