Mars - helps us work, rest and pray?

I've just been watching the news reports on the Gaza strip conflict. What the hell are we doing to each other? No matter where war takes place it's the innocents in the middle who suffer - men, women and children - on both sides. Am I wrong in thinking that the average citizen of any country is seen as cannon fodder by its Government? Unless we have a value - which we appear not to (other than when those same governments need us to become part of their army) then we seem to be expendable. Each time I see news reports of people being blown to pieces I see me, and my family. I can't imagine the terror the children of conflict must feel every day, wondering if the next missile has their name on it. And the parents too on both sides - people like you and me - how can they protect themselves and their children? The simple fact is they can't - and that can't be right. I really wish I had the answer - more importantly, I really wish governments had the answer. What niggles me is that we can afford to spend ten billion on the Olympic Games - and god knows what on the prospect of getting to Mars, but not on saving lives. Maybe someone knows we might need althletes to populate Mars when we finally blow this planet of ours to bits.
