I think most people don't even know why we're fighting these wars anymore. It was Osama, it was WMD's, it was Taliban, it was Al qaeda, it was terror, it was Saddam, it was to help the Afghans, it was to help Iraq's, it was for oil, it was for American interests and on and on. They are overdosed on these nicely named objectives that don't always pan out only to hear about more objectives and longer wars. If the public witnessed a more personal connection to American soilder death don't you believe the people, through their elected officials would put more preasure on all the administrations to make better choices in how they deal with future confrontations?
I hope I was able to convey what I'm thinking clearly enough, it was a long day.
