See, this is what war does to people. It causes more and more violence. Sure, maybe sometimes war will get rid of a ruthless dictator, but truly, that is only delaying man's demise. War only causes more anger and hatred. Maybe not from a large group of people, maybe from a small group of people, but people are easily manipulated, and that small group soon turns into a large one and more violence pursues. War never ends, and it never shall. It's just a virus that subsides for a while, only to come back, with more destructive technology. And true, you can argue that man's will to live shall stop him from using nuclear weapons, but it is that same will that shall cause him to use them.
