"[Unmanned] War, what is it good for?"
Looking far into the future, wars will probably be fought between unmanned robots and vehicles. So will there be any point at all? If nobody dies, is it still worth calling a war?
As for the near future, the US is most likely going to start using more unmanned combat vehicles instead of risking the lives of its soldiers. This puts the US at an incredible advantage—the ability to kill an enemy and not lose any soldiers, making war virtually one sided. (Will this bring a rise in terrorism?)
