Secretary of Defense Chuck Hagel met with Sweden’s Minister of Defense Karin Enström at the Pentagon today, Pentagon Press Secretary George Little said.

As I look back over these past four years in particular, there were a number of solid accomplishments and a few stubborn difficulties -- but at the center of it all were wonderful human relationships.
