Has NATO become a paper tiger, trying (and failing) to stand up to a resurgent Russian bear? A speech by NATO Secretary General Jens Stoltenberg at the Center for Strategic and International Studies on Wednesday addressed this issue, discussing both the challenges facing the 66-year-old alliance, and Stoltenberg’s vision for its future in what he termed a “changed” security environment.

 “The challenges we see coming from the south are clear and they are coming from Russia,” the Norwegian general said.
