Biden tells AQ how to get US out of Iraq

How else can you interpret this?

Vice President Joseph Biden told Iraqi leaders that the path to a secure peace lies in uniting ethnic and sectarian groups and said the U.S. might disengage from their country if it reverts to sustained violence.

He also told Maliki that if Iraq fell into a period of sectarian violence or engaged in ethnic fighting, such a step would change the nature of U.S. engagement, a senior administration official said, according to the report. The aide did not offer specifics about the change, it said.
