Since we are in the mood of quoting troops in Iraq, here's a good one.
This letter was sent by mail from Iraq from Specialist Mike Prysner:

Dear Mr. Moore:
I’m writing this without knowing if it’ll ever get to you. I’m writing it not knowing why, or knowing what I’m going to say. I’m writing it not knowing if I’ll ever finish it or mail it. I’m writing it from the trenches of a war (that’s still going on,) not knowing why I’m here or when I’m leaving. I’ve toppled statues and vandalized portraits, while wearing an American flag on my sleeve, and struggling to learn how to understand.

I was in Vicenza, Italy when I heard your Oscar acceptance speech. It was the day before I boarded a plane and experienced a “combat landing” in uncharted territory in northern Iraq. It was such a surreal feeling—the only light came from a red bulb—we sat shoulder to shoulder in silence. We were told to expect heavy artillery/chemical attacks. I can’t say I know what was on the minds of those men packed next to me, but I assume it was thoughts of family and religion. But me, a single 20 year old, I was thinking about what you had said. I joined the army as soon as I was eligible – turned down a writing scholarship to a state university, eager to serve my country, ready to die for the ideals I fell in love with. Two years later I found myself moments away from a landing onto a pitch black airstrip, ready to charge into a country I didn't believe I belonged in, with your words repeating in my head.

My time in Iraq has always involved finding things to convince myself that I can be proud of my actions; that I was a part of something just. But no matter what pro-war argument I came up with, I pictured my smirking commander-in-chief, thinking he was fooling a nation. I discovered that the result of the war and the actions of G.W. cannot be treated as the same issue. Bush accidentally did a good thing for the Iraqi people. After the fact he's starting to claim humanitarian intentions for going to war - obviously bullshit. But he realizes that that is the only positive outcome. I could explain what I've seen here; a people forced into poverty & ignorance – but I'll spare you. I try not to think about the ultimate future of this place. I'm sure we'll cause them to fall victim to Banana Republic and Joe Millionaire, with a puppet president and monopolized oil industry. But there will be plenty of time in the future to worry about those things.

I can't say I know what I believe. I am willing to accept that my opinions are a result of a given subconscious, not sufficient knowledge. Do I support care for the low income class because I truly understand the system, or because I've personified inadequacies and identified with those who experience struggle. Does a conservative oppose gay rights because he genuinely understands the issue or because he's scared to face deeper levels of humanity? What if you could be given a reason for everything you believe, but the reason is unrelated to the topic – the result of a life and a psyche? Will we believe those things the same way we used to? I call myself a liberal because I've been moved to tears by the words of Paul Wellstone, scenes in "The Awful Truth," the funeral of Matthew Sheppard, and the homeless people in the city I once lived in. It's not what I know, it's what I felt. It's dangerous to rely on emotions to guide your moral compass – but it’s the only way to be honest. I understand everything I believe may be wrong; that I believe for a reason, and that reason may not be reality. I'm not sure what I'm trying to say. Maybe just that I can't look at this war politically. I can only look at it as an experience that has taught me that life is dictated by seconds and inches; one that has caused me to face death and loss and fear. And at its core, stripped of the WMD's and no-contest contracts, it's been about one thing: serving my country. The most difficult thing has been learning how to be proud of that. This country, I'm serving,…is it America? Has it ever been? It's always bothered me that, despite the American philosophy, it became NECESSARY for a civil right movement, it became NECESSARY to form the ACLU. I've simultaneously battled Saddam loyalists and these questions. Kind of an odd setting for suddenly doubting my patriotism. But while my fight with those trying to kill my friends & I is far from ending, the fight within myself has ended.

I found what I've been fighting for. It's been you, all along. I hated you on a plane ride in the dark with shaking hands. But you've been the roof of my loyalty, my bravery, and my dignity. Mr. Moore, you are America. This isn't a "I'm a hip liberal & I'll be cool if I get an autographed copy of Stupid White Men" letter. I've faced every weapon, from SCUDs to swords, and I've had to face why. And you've been the answer. I'm serving a country in which you live; where you're allowed to speak and PEOPLE LISTEN; where you're allowed to write and PEOPLE READ. What a beautiful country – every injustice has a prosecutor – every struggle has a defender. We are still a country being born. Compassion will never lose to conservatism…the country could be ruled by Jerry Falwell and Dick Cheney – but there will always be tears, as long as there is injustice and oppression and greed and hypocrisy. And there will always be you, the people you've taught, the lives you've influenced. You reminded me that America exists, and I suppose this letter is meant to thank you for that. I can't explain the pride you've instilled in me, and the comfort you've given me, to know that if I find myself fallen on the battlefield, I gave my life serving something I loved and truly believed in.

Sincerely,
Mike Prysner
