Interesting article. Shows how the war in Afghanistan differs greatly from Iraq in that the Afghan struggle has not yet turned into a sectarian struggle as it largely has become in Iraq. Someone correct me if I'm wrong, but the Taliban are still largely fighting on their own ethnic homeground in the south and east, among fellow Sunni Pashtuns --- unlike Iraq where suicide bombing is principally aimed at intimidating civilians and leadership of another sect. Suicide bombings of Sunnis by Sunnis in Iraq are rare.
