Nature of security threats have changed, says European affairs expert

Bruce I. Turner, acting director of the Office of European Security and Political Affairs from the Bureau of European and Eurasian Affairs at the U.S. Department of State, says that nature of security threats have changed and that weapons of mass destruction have fallen into the hands of non-state actors. Turner points out that the emergence of competing powers has made it more important to cooperate with other countries which share the same values.(0:53)
