In The Honest Broker I have a chapter that evaluates the role of intelligence in the decision to go to war in Iraq. I argue that intelligence was used by the Bush Administration as a tool of political advocacy rather than policy insight. With the release earlier this week of a new intelligence estimate on Iran, it may be that the intelligence community is regaining some of its credibility. The New York Times today explains some changes that have taken place:

Over the past year, officials have put into place rigorous new procedures for analyzing conclusions about difficult intelligence targets like Iran, North Korea, global terrorism and China.

Analysts from disparate spy agencies are no longer pushed to achieve unanimity in their conclusions, a process criticized in the past for leading to “groupthink.” Alternate judgments are now encouraged.

In the case of the 2007 Iran report, “red teams” were established to test and find weaknesses in the report’s conclusions. Counterintelligence officials at the C.I.A. also did an extensive analysis to determine whether the new information might have been planted by Tehran to throw the United States off the trail of Iran’s nuclear program.

One result was an intelligence report that some of the intelligence community’s consistent critics have embraced.

“Just possibly, the intelligence community may have taken a major step forward,” Senator Rockefeller said.
