It’s been a tumultuous year for U.S.-Pakistan relations. First came the arrest of a CIA contractor in Lahore who killed two Pakistani citizens, then the raid by U.S. special forces that ended in the death of Osama bin Laden. But relations hit a new low last month when a NATO air strike killed 26 Pakistani soldiers. A Pentagon report released Thursday says both countries share in the blame for the deadly attack, that Pakistani forces fired first. Marvin Weinbaum, scholar-in-residence at the Middle East Institute and a former State Department Analyst on Pakistan and Afghanistan, discuss the report’s findings.
