Jason mentions a hell of a quote by Wolfowitz, but I found another entry that brings the quote into doubt. Another AP article (sorry, no link) that yields another context:
The United States hopes to end the nuclear standoff with North Korea by putting economic pressure on the impoverished nation, U.S. Deputy Defense Secretary Paul Wolfowitz said Saturday.North Korea would respond to economic pressure, unlike Iraq, where military action was necessary because the country's oil money was propping up the regime, Wolfowitz told delegates at the second annual Asia Security Conference in Singapore.
"The country is teetering on the edge of economic collapse," Wolfowitz said. "That I believe is a major point of leverage."
"The primary difference between North Korea and Iraq is that we had virtually no economic options in Iraq because the country floats on a sea of oil," he said.
