The best case for the war in Iraq. He (Friedman)'s not worried about Saddam and his WMD - they are deterrable with conventional weapons.
What worries him are the "undeterrables" - the real threat, the 9/11 guys. A project that says we can partner with an Arab state and create an accountable transparent gov't that is leaning forward in the right direction, as a model and inspiration for other progressives, as the first step in a long term project. If we can do that, it's worth doing in moral terms and will get at the origin of the real threat - the undeterrables who hate us more than they love life.
"If we don't turn around now, we just might get where we're going." If you think the status quo is benign, think again.
Now, against the war...
It's the right thing to do, but we just can't do it right. It's a bridge too far. Iraq is a black box - when we open it, we don't know what kind of demons are going to fly out of it. There will be an envelope inside that tells us what we've won - it could be postwar Germany, or Yugoslavia.
A state congenitally divided between Kurds, Shia and Sunnis, that can only be ruled with an iron fist.
"Congratulations, you're the new Saddam Hussein".
In the first envelope, Iraq is the way it is because Saddam is the way he is. In the second envelope, Saddam is the way he is because Iraq is what it is.
And he who rules Iraq will become more and more like Saddam. There's a real chance that it's the second envelope we'll get.
For him it's not an argument against the war, but an argument for why we must do it right (i.e. with maximum amount of allies, UN endorsement, understanding of the American people about what this project is about). This isn't going to be a sprint - it'll be a marathon.
He's still struggling with the idea of the war in Iraq. We may have passed the point where we could generate the support we need to do the right thing right.
To do it alone, snubbing the UN and the rest of the world, would be a huge mistake. It is imperative that if this goes forward, that it not be out of some ideological pique, not because we couldn't back down, but because we're really doing the right thing on the basis of a value judgment.
There is a chance if we do it right, the end will justify the means.
If we do it wrong, on the other hand...
