CrossTalk: Shiite vs. Sunni

­On this edition of Peter Lavelle's CrossTalk:  Is the Sunni-Shiite conflict ingrained in political Islam? Can this split play into the hands of those who divide and conquer? Is it being portrayed as the undercurrent of every dispute in the Muslim world? And are the clashes in Bahrain and Saudi Arabia more about Sunnis and Shiites than about fighting against injustice and corruption? Guests: Juan Cole, Hisham Hellyer and Stephen Schwartz.
