The use of Atomic bombs on Japan during world war 2 was the correct moral choice. It saved countless human life, and brought a swift end to the war.
Also who knows how much other death would of occurred had the world not born witness to the devastating power of those bombs.
The fear of those weapons, kept first world nations relatively peaceful towards each other. Now some of you may be thinking "What about the Cold War?". Well that speaks to my point as well.
Even after WW2 nations were still aggressively pursuing their own agenda's against one another, but i feel the power of the Atomic Bomb is what made them change their game up.
In short the bombings of Hiroshima, and Nagasaki while deeply unfortunate incidents, have saved countless lives.
Our fire bomb campaign that preceded the nukes were many times more devastating. Japanese cities were still wooden back then. Conducted by Gen. LeMay, America razed Japan to the ground. The nukes were redundant.
