The Ghost of RubangB on 17 May 2009
Not worth the loss of life or the loss of money. Either one of those (and definitely both) outweigh any potential unintentional benefit for a possible third party in the distant future.
Like Kasz said, it's really too early to tell, considering all the factors and effects and how long they'll take to truly settle and be observable.
But in my opinion, letting thousands of Americans and between 90,000 and 100,000 CONFIRMED civilians die for potential benefits is stupid, murder, and a waste of time, money, life, and credibility.
We went in to Iraq because everybody wanted blood after 9/11, and our war killed more than 30 times as many civilians. If anything good ever comes out of it, we shouldn't be celebrating.
