##Seven Billion Reason to be a Pacifist In World War II, only one of the combatants, America had nuclear weapons, and that combatant had only three or perhaps four. One was used to test the prototype in New Mexico. Two were dropped on Japan, and the fourth one was not used. The Hiroshima blast destroyed more than 10 sq km (4 sq mi) of the city, completely destroying 68 percent of Hiroshima's buildings, another 24 percent were damaged. Nearly 130,000 people were killed; more than 60,000 were incinerated almost instantaneously in a tremendous fireball. In Nagasaki one-third of the city was destroyed and nearly 66,000 people were killed. This was in 1945. Today the five acknowledged nuclear powers possess about 31,000 nuclear warheads.These weapons are much more powerful and can be delivered anywhere on Earth with the touch of a button. Link ]
