Any direct confrontation with Russia may go nuclear. The NATO doctrine understandably requires a direct attack on a NATO member to run that risk. In my opinion, Russia will not have a lot of appetite for further aggression after all those sanctions. Invading NATO members and setting off a huge, unwinnable conflict should be pretty far down the list of priorities in the next few years.
