Iraqi author Ghaith Abdul-Ahad on the 'unbuilding' of Baghdad

Iraqi author Ghaith Abdul-Ahad has a new book called, "A Stranger in Your Own City: Travels in the Middle East's Long War." It's an ode to a city shattered by war. Abdul-Ahad speaks with The World's Marco Werman about his childhood home, the cycle of sectarian violence set in motion by the US-led invasion in 2003 and what might lie ahead for the centuries-old, cosmopolitan city.
