But when it's just machines blowing up machines, a war/conflict goes nowhere. I don't think countries or political entities will give up, surrender, etc. unless there is a real consequence for their actions. The only way a point is going to be made is if people die. Why not just have the leaders play Halo, and the winner get's his political desires? The only way I could see you losing a war like that is just to simply run out of money because you kept replacing all your UAVs (or robot infantry and whatever the future holds for us) that were shot down.
Not only that, but you are going to lose some real heroes. This country needs those people that are willing to go into harms way to defend our country, our freedoms, and our way of life. And when those people leave the military I want to see them as politicians, because they know what it means to sacrifice. And in turn, I would hope that sacrifice would lead them to make well informed, and ultimately better, decisions when it comes to war.
Something is definitely lost when you're just sitting behind a console pushing a red button.
Just my thoughts on the subject.
