Nora Bensahel is a senior political scientist at the Rand Corporation and an expert on American efforts in Afghanistan and Iraq. She explains the differences between the conflicts and objectives in Afghanistan and Iraq. Bensahel addresses President Obamas metrics system against terrorism and the Taliban-led insurgency. She also describes the upswing in violence in Iraq following the U.S. pullout from Iraqi cities in June, but says enduring acts of violence may be an indication of the weakness of the Iraqi government. http://worldfocus.org/blog/2009/08/19...
