I do not think you are getting what I am saying. As humans, I have no doubt, when put into a situation where you have to go to war, people will. This "weaker" you speak of, PTSD was not even a thought then. Maybe give this a watch: http://www.youtube.com/watch?v=TqFaiVNuy1k&feature=player_embedded Generation after generation things are figured out, times change, people live longer, but that doesn't mean people can not fight wars. Mental health is more understood. I am pretty sure, when the country was at war, if you had 2 arms and 2 legs, you were probably going to go off to war. Things are different in a time of need. Do you think less about people went to Vietnam or Desert Storm or Iraq/Afghanistan? No, but a good amount of them come home with PTSD, and it is sad. It is more understood, and treatable, but not 100% curable. I have a cousin who was a Sarge in the Army, who came a couple years ago, after being in Iraq. He can't eat in restaurants because of the PTSD. It is really sad, and I have a ton of respect for him.
