General Petraeus: U.S lack "understanding of tribal relationships"

U.S. General David Petraeus explains Afghan war strategy to U.S. Navy Adm. Mike Mullen and reiterated his predecessor Gen. Stanley McChrystal that the U.S lacks "understanding of local circumstances, customs and tribal relationships."

Comparing Afghanistan to Iraq, Gen. Petraeus said. "One of the key elements in our ability to be agile in our activities in Iraq during the surge was a pretty good understanding who the power brokers were in local areas, how the systems were supposed to work, how they really worked."
