The Russian military "will watch with much attention what means might be necessary to neutralize the risks" associated with NATO’s growing activity.

"It’s all too obvious that measures will be taken and our partners at the Russia-NATO Council shouldn’t get surprised over it," Grushko said. "All the realistically thinking politicians and military realize that any action will trigger an equal counteraction sooner or later."
