well off topic, gronne, i live in america and i wholly agree with you, and your pretty much right about how americans think
on topic, there are few cons, but one is they didnt 100% need to do it
if they were going to kill innocent people anyways, they could have blockaded japan (would have took a long time, but itd work) along with lots of conventional bombing and then an invasion after a year or two
and who ever said germany would have won the arms race, your a retard.
we had just defeated germany and a) by setting off a nuclear bomb that wouldnt have prevented germany from winning an arms race, and b ) wtf is with everyone with there, america wins everything, attitude?
