War is cruel but so is overpopulation that has caused many wars. Think about what the world population would be now if nobody had been killed in wars ever. We would be having to start wars to protect what we have to live on, for jobs and even to keep diseases out of countries. Yes, war is cruel but as long as man can't live within reason war will happen. Overpopulation will be the next big problem and what is being done to stop that, have any good ideas?
