You grew up wanting so bad to be Luke Skywalker, but you realize that you were basically a Stormtrooper, a faceless, nameless rifleman, carrying a spear for empire, and you start to accept the startlingly obvious truth that these are people like you.
Question: How do you Americans as a people walk around head held high, knowing that every few months your country is committing a 9/11 size atrocity to other people. Imagine if the 9/11 terror attacks were happening in America every few months. Again and again, innocent people dying all around you. Your brothers and sisters. For no reason.
Daniel Crimmins from U.S. Army 3rd Infantry Division answered:
Many of us are unable. Many of us watched 9/11, and accepted the government and media's definition of the attack as a act of war rather than a criminal action. A smaller portion, drifting along passively thought a major war was coming, that people we knew were going to fight and die. Some of us maybe worried about our younger brother being drafted, despite being in college. Now, it seems stupid, but in the 72 hours after 9/11, some Americans, maybe suffering from depression, certainly with a mind shaped by comic books and action movies, ate up the "us vs. them" good vs. evil rhetoric spouted by the cowboy in chief. After all, he was the president, and no matter how bright you might think yourself, you can still be swayed by passion and emotion, led to terrible decisions.
