What's next for the NATO mission in Afghanistan?

NATO Secretary General Anders Fogh Rasmussen weighs in on the mission in Afghanistan moving forward: NATO must operate abroad to defend interests.

NATO must be willing to be involved in conflict away from the immediate geography of the member nations, the group's secretary general told CNN's Candy Crowley on Sunday.

Rasmussen was responding to a Security Clearance article by CNN Foreign Affairs Reporter Elise Labott which reported that the decade-long NATO involvement in Afghanistan has produced what some have described as collective fatigue among European allies and questions about whether NATO should be involved in conflicts outside of Europe's backyard.
