President Barack Obama says a tightly focused war strategy in Afghanistan will help with the hunt for the elusive Osama bin Laden.
Obama says that when he took office, the US approach in Afghanistan "was somewhat adrift." He's working to get back to the original goal, going after al-Qaida, who masterminded the September 11 attacks.
Obama tells CNN's "State of the Union" that if the focus starts to drift from that goal, "then we may have a problem." He says he knew that hunting down bin Laden was going to be hard. Bin Laden and other senior Al-Qaida leaders are presumed to be hiding across the border in Pakistan, in a mountainous region where the US-supported government in Islamabad has little control.
