Maybe it was not an option in his life when he was young. You do realize that when Cheney was in his early twenties his generation was not in a war at that time. How do you even know if he did or did not serve in some capacity? Fighting in a war zone is not the only way to serve your country. And why does it matter to you, anyway? My father wanted more than anything to go into the military and fight in WWII, but they rejected him for a medical reason. How do you know Cheney didn't have a medical reason? What gives you the right to judge, anyway?
