Pentagon: NATO not a threat to Russia

NATO is not a threat to Russia, and Moscow is aware of this fact, US Defense Secretary Jim Mattis told CBS News in an interview.

"Right now, Russia's future should be wedded to Europe. Why they see NATO as a threat is beyond me. Clearly, NATO is not a threat. But right now, Russia is choosing to be a strategic competitor for any number of reasons. But the bottom line is NATO is not a threat and they know it. They have no doubt about it," Mattis said.
