This is my opinion and you can take it for what it's worth, but I thnk we never should have EVER nuked Japan. We are the only country in history that has ever used weapons of mass destruction in war. We have that technology, yet we tell other countries they can't? The government is doing to them what they are doing to the citizens. They are disarming other countries (Or at least trying to) and then wonder why other countries are wanting to attack us...oh I don't know George, perhaps they are trying to attack us before we can attack them. This world is starting to scare the piss out of me.
EDIT: Because I'm getting tired of seeing it and answering it; Yes, I have heard of Pearl Harbor. However, Pearl Harbor is NOT the reason we nuked Japan. Pearl Harbor is why we joined the war. Until that point, we had a stayed a nuetral country. We nuked Japan to end the war, not to get revenge for what they did to Pearl Harbor.
