oh if you start something with north korea they have tens of thousands of artillary pieces pointed at seoul a city of 25 million and china has already said if we attack n korea they will defend them just like in the Korean war witch by the way is still going we never declared a peace treaty so you really want ww3 you might want to think about this one,oh we could not deal with a nuclear soviet union then we could not deal with a nuclear china and so on but we have found ways around these others we can deal with this without starting ww3 because we could not deal with a nuclear n korea,because any country realizes if they hit us with a nuke or 2 we will wipe them from the face of the earth hey if it could deter the soviets with their 6,000 nukes I think we can handle the poverty striken third world country like n korea and their couple of nukes
