Are nuclear weapons threat to world peace?

War is part of the human condition. We started by throwing rocks and beating each other with sticks. Every time a new technology is developed people declare that it will be the weapon that will end the ability to wage war because the cost of hate has gone up to an unacceptable level. I know of several examples the recurve bow, gunpowder, crossbows, rifles, machine guns, flame throwers, napalm, and now nuclear weapons. Nuclear weapons give cause to the war mongers to seek diplomatic and covert solutions rather than to go head to head with your opponent. But nuclear weapons have nothing whatever to do with world peace because if it did people would have already stopped shooting at each other after the first nuclear weapons were used back in 1945. In the end nuclear weapons are just another crossbow, capable of killing hundreds of thousands of people at a time. Non combatants have always born the heaviest toll of war, now the warmongers can kill us faster.
