Just a random photo. This is Colonel Paul Tibbets, pilot and Commander posing with perhaps the single most famous aircraft in history, the B-29 Superfortress Enola Gay, the aircraft that dropped the nuclear bomb over Hiroshima on August 6, 1945. This WAS NOT the deadliest air raid in history. The March 5, 1945, firebombing over Tokyo killed more people in a single raid than both nuclear weapons combined, 150,000 people and made one million homeless using conventional incendiary, aka napalm, bombs. So, you don't need nuclear weapons to kill lots of people. A strike at the Three Gorges dam in China which could cause a gigantic downstream flood, could kill as many as 3-4 million dead.
