NATO Secretary General Jens Stoltenberg is not naïve about the continued threat that Russia poses to his organization, which was founded shortly after WWII to counter Soviet aggression. But he also sees a silver lining in Putin's belligerent moves. "For the first time in many years, allies are investing more in defense. And all of this is very much triggered by Russia's behavior since 2014." Stoltenberg also believes that a critical step to confronting Russia will be to beat them on the cyber battlefield. His conversation with Ian Bremmer was part of the latest episode of GZERO World, which begins airing nationally in the US on public television November 13th. Check local listings.
