I'd say that the circumstances surrounding the dropping of the two a-bombs justified the action of doing so. It was an impressive weapon and together with the Soviet entry in the war on Imperial Japan helped end the war in a short time instead of conducting a protracted and bloodier campaign through the entire Japanese island chain. It was still a horrible thing to do but more Japanese would have died if the war continued on an the land invasion was needed not to mention the continued firebombing of Japanese cities.

I'd think you'd understand that WWII was one heck of a circumstance in which to use such weapons, weapons for which the US wasn't even aware of the long lasting radioactive effects. How does this reduce the US moral authority in trying to limit how many countries have access to such powerful weapons. Why does this make it okay for you to stab at MY ancestry in the same way? Do past wrongs or horrors by previous generations mean that the current generation is equally as guilty and unfit to see the horror that the weapons can cause? We could make endless analogies of current countries decrying something their countrymen of a previous generation did but that shouldn't mean that the current generation should not be allowed to or be considered hypocritical because they oppose such outrages.

Do you think that the US should not try and limit the spread of nuclear weapons?
