Petraeus adviser: Violence reduction due to ‘luck.’

In an interview with the Council on Foreign Relations, Gen. David Petraeus’s adviser Stephen Biddle said that much of the U.S.’s recent “tactical successes” in Iraq have little to do with the impact of Bush’s escalation but instead are largely “luck.

Q: Well what do you attribute this whole change on the ground to? Is this due to what is called “the surge,” or good diplomacy by the U.S. military, or just luck?

BIDDLE: All of those things have some role but I would put “luck” as probably the biggest.
