Former Norwegian prime minister Jens Stoltenberg pauses during an address to the media in Oslo, after NATO ambassadors chose him to be the next head, March 28, 2014. NATO chose Stoltenberg as its next leader on Friday at a time when the Western military alliance must deal with a resurgent Russia following its annexation of Ukraine’s Crimea. Stoltenberg will take over as secretary-general of the 28-nation grouping on Oct. 1, succeeding former Danish prime minister Anders Fogh Rasmussen, who has led NATO since 2009.
