Osama bin Laden has been killed at last, but America's leaders are not saying "Mission Accomplished" in Afghanistan. Is al Qaeda still a threat in that country or is the Obama Administration's massive military commitment an example of "mission creep?" The White House calls nuclear-armed Pakistan "a key partner in the fight against al Qaeda and terrorism." But CIA Director and prospective Secretary of Defense Leon Panetta told a congressional briefing, "Either they're involved or incompetent." Did Pakistan knowingly shelter Osama? Is it a friend, a foe or an ally of necessity? We ask if it's time for the US to reassess strategy in a dangerous part of the world.
