That is new. I thought that their dealing with Russia regarding rocket hardware is way back in the past. So Russia decided to help out N. Korea recently? I wonder why.
For the same reason that they worked together in the Sony Hack
Are you serious? Russia is on the move right now in their quest to restore their lost empire. They are basically trying to bring back the Soviet Union, under the guise of combating terrorism. In fact, they are likely encouraging the terrorism in one way or another, as they have been suspected of doing on several other occasions in the past, in order to give them cover for moving in and ultimately grabbing control of the Middle East, or at least a substantial part of it. The saboteur-in-chief (Obama) has paved their way with his promised "flexibility" on missile defense and nukes (New START nuke treaty and the Obama-Putin Iran nuke deal).
