Eh, I know it isn't PC these days but but dropping the atom bombs was the right thing to do, at least from the US's side. A Japan mainland invasion would have been bloody as all get out becuase you know they would not have surrendered. I mean, look at how they fought to the death on random pacific islands, imagine their mindset defending their homeland.

Having said that, I do no believe in a "proportioanl response doctrine" so Japan had no say in how we attacked them seeing as they attacked us first.
