I am jumping on this string late, but aren't the answers we are posing begging for a question?
In my opinion the question is not what should have been done, but why wasn't it done?
I have never been endowed with whatever might call foresight in a crisis, I have always just responded. In Italy I caught a flash of light and ducked as the USO blew up down the street, car parts and glass landed all around me. On the South China sea I saw a Japanese woman and her child disappearing out to sea on a blowup raft, while her family and relatives stood there wringing their hands. I was the one who looked up and saw what need to be done, I swam out and pulled them in, I was 13. On the underground in Munich I was confronted by a half dozen Turks who thought my girlfriend might show them a good time. I figured out who the leader was and went for his throat, it was not turning out well by the way but at the next stop there were quite a few of my friends waiting for me. I doubt seriously if any of those particular Auslander wander the underground looking for American victims anymore. The funny thing is I thought all Americans were like me, I was raised in a warrior culture on bases around the world.
When you join or are drafted into the military the government does not hand you a rifle, a 60 pound rucksack, and a killer attitude. You are trained to acquire a killer attitude then you are handed a rifle or a sword, spear, rock, whatever, the implement is unimportant when you are a warrior. Many people on this board are warriors, we have either been trained or have trained ourselves to respond to external threats with aggression and tenacity.
So how do we change this? How do we get American to become Citizen Warriors again? That's really the question isn't it?
