Is Iraq the source of our problems?

From a CBS News/New York Times Poll:

"From what you know, how much do you think the cost of the war in Iraq has contributed to the U.S. economic problems: a lot, some, not much or not at all?"

A Lot, 67 %
Some, 22%
Not Much, 6 %
Not at all, 4 %
Unsure, 1 %

I have never taken a public position on the Iraq war: The issue is a hard one, and foreign policy and military matters are well beyond my area of expertise. But I am confident that it would be a mistake to view the war primarily through the lens of economics. My guess is that if this poll question were asked of professional economists, most would answer "Not Much."
