A U.S. Chinook helicopter flies over the border area between Afghanistan and Pakistan, Spin Boldak August 28, 2011. The Afghanistan-Pakistan border is porous, long and teems with illegal activity, from the Taliban insurgents who hop back and forth to the enormous amounts of weapons, explosives and narcotics that are smuggled across it.
