Yet what, and how, should we feel? People are not on their oath when speaking of the dead, but I have now talked to a good number of those who knew Mark Daily or were related to him, and it's clear that the country lost an exceptional young citizen, whom I shall always wish I had had the chance to meet. He seems to have passed every test of young manhood, and to have been admired and loved and respected by old and young, male and female, family and friends. He could have had any career path he liked (and won a George C. Marshall Award that led to an offer to teach at West Point). Why are we robbed of his contribution? As we got to know one another better, I sent the Daily family a moving statement made by the mother of Michael Kelly, my good friend and the editor-at-large of The Atlantic Monthly, who was killed near the Baghdad airport while embedded during the invasion of 2003. Marguerite Kelly was highly stoic about her son's death, but I now think I committed an error of taste in showing this to the Dailys, who very gently responded that Michael had lived long enough to write books, have a career, become a father, and in general make his mark, while their son didn't live long enough to enjoy any of these opportunities. If you have tears, prepare to shed them now …

In his brilliant book What Is History?, Professor E. H. Carr asked about ultimate causation. Take the case of a man who drinks a bit too much, gets behind the wheel of a car with defective brakes, drives it round a blind corner, and hits another man, who is crossing the road to buy cigarettes. Who is the one responsible? The man who had one drink too many, the lax inspector of brakes, the local authorities who didn't straighten out a dangerous bend, or the smoker who chose to dash across the road to satisfy his bad habit? So, was Mark Daily killed by the Ba'thist and bin Ladenist riffraff who place bombs where they will do the most harm? Or by the Rumsfeld doctrine, which sent American soldiers to Iraq in insufficient numbers and with inadequate equipment? Or by the Bush administration, which thought Iraq would be easily pacified? Or by the previous Bush administration, which left Saddam Hussein in power in 1991 and fatally postponed the time of reckoning?

These grand, overarching questions cannot obscure, at least for me, the plain fact that Mark Daily felt himself to be morally committed. I discovered this in his life story and in his surviving writings. Again, not to romanticize him overmuch, but this is the boy who would not let others be bullied in school, who stuck up for his younger siblings, who was briefly a vegetarian and Green Party member because he couldn't stand cruelty to animals or to the environment, a student who loudly defended Native American rights and who challenged a MySpace neo-Nazi in an online debate in which the swastika-displaying antagonist finally admitted that he needed to rethink things. If I give the impression of a slight nerd here I do an injustice. Everything that Mark wrote was imbued with a great spirit of humor and tough-mindedness. Here's an excerpt from his "Why I Joined" statement: Anyone who knew me before I joined knows that I am quite aware and at times sympathetic to the arguments against the war in Iraq. If you think the only way a person could bring themselves to volunteer for this war is through sheer desperation or blind obedience then consider me the exception (though there are countless like me).… Consider that there are 19 year old soldiers from the Midwest who have never touched a college campus or a protest who have done more to uphold the universal legitimacy of representative government and individual rights by placing themselves between Iraqi voting lines and homicidal religious fanatics.

And here's something from one of his last letters home:
I was having a conversation with a Kurdish man in the city of Dahok (by myself and completely safe) discussing whether or not the insurgents could be viewed as "freedom fighters" or "misguided anti-capitalists." Shaking his head as I attempted to articulate what can only be described as pathetic apologetics, he cut me off and said "the difference between insurgents and American soldiers is that they get paid to take life—to murder, and you get paid to save lives." He looked at me in such a way that made me feel like he was looking through me, into all the moral insecurity that living in a free nation will instill in you. He "oversimplified" the issue, or at least that is what college professors would accuse him of doing.

In his other e-mails and letters home, which the Daily family very kindly showed me, he asked for extra "care packages" to share with local Iraqis, and said, "I'm not sure if Irvine has a sister-city, but I am going to personally contact the mayor and ask him to extend his hand to Dahok, which has been more than hospitable to this native-son." (I was wrenched yet again to discover that he had got this touching idea from an old article of mine, which had made a proposal for city-twinning that went nowhere.) In the last analysis, it was quite clear, Mark had made up his mind that the United States was a force for good in the world, and that it had a duty to the freedom of others. A video clip of which he was very proud has him being "crowned" by a circle of smiling Iraqi officers. I have a photograph of him, standing bareheaded and contentedly smoking a cigar, on a rooftop in Mosul. He doesn't look like an occupier at all. He looks like a staunch friend and defender. On the photograph is written "We carry a new world in our hearts."

Two weeks before he was killed in action, last January, Mark Daily relaxed on the rooftop of Combat Operating Base "Resolve," in Mosul.

In his last handwritten letter home, posted on the last day of 2006, Mark modestly told his father that he'd been chosen to lead a combat platoon after a grenade attack had killed one of its soldiers and left its leader too shaken to carry on. He had apparently sounded steady enough on the radio on earlier missions for him to be given a leadership position after only a short time "in country." As he put it: "I am now happily doing what I was trained to do, and am fulfilling an obligation that has swelled inside me for years. I am deep in my element … and I am euphoric." He had no doubts at all about the value of his mission, and was the sort of natural soldier who makes the difference in any war.
