Re: Wasn't this handled last time?
There's a good argument for Hiroshima and Nagasaki to be war crimes. Both were committed after Japan had started looking to make peace, but prior to surrender. Documents at the time show that the real reason for Hiroshima wasn't to stop the war but as a warning to Russia. Nagasaki was to show they could do it more than once. However, the plan backfired and only spurred on Russia's attempts to build their own bomb.
