to the statement of China or anyone else using nukes at all. 8. 8 is the number iof nukes it would take to destroy the world and cause a nuclear winter in which teh sky will be blocked out and all sorts of plants and animals will die and become extinct, probably including us. If one is launched it will cause a chain reaction of everyone sending their nukes out. That is alot more than 8. If anyone sends a nuke out we will all die and I doubt anyone will be stupid enough to do that.
