You really should read the debate about the bombing:

Also, the poster above stated a simple fact: no other country has ever used nukes in anger. I don't think it's necessary to contextualize this simple statement.

I'm familiar with it. Personally I don't see any clear or compelling evidence that the bombings did not play a role in ending the war. It's not as if the Allied Commanders had direct access to the inner circle of Japanese leaders at the time. History is never as black and white as some may portray it - I don't doubt that there were many complex reasons for the decision to use the bombs and the decision made by the Japanese to surrender.

Personally, I also think it's a bit ridiculous to be ashamed of the fact that the US dropped two nuclear weapons as part of ending a global war. These were primitive weapons compared to what is available now. Were they any worse than the firebombing of Tokyo or Dresden? Any worse than the atrocities in Nanking? Worse than the Holocaust or actions of the Einsatzgruppen? What about the Katyn Forest? Comfort Women? The treatment of POWs? WW2 was full of horrible events that every nation could be ashamed of but let's not forget the context of the conflict and who the aggressors were.
