I doubt that the Russians have forgotten the last time they tried to invade Finland.But a strong fighter/air defense presence should be a high priority.We already conduct exercises in Norway.If Russia wants war there are easier plums for them to pick than the frozen north. http://www.usnews.com/news/world/articles/2016-11-03/natos-northern-flank-vulnerable-to-russia
STOCKHOLM – Officials in Finland, Sweden and Norway are concerned about what have become almost routine acts of Russian aggression, how they can respond, and whether they could prevent an incident, or even an accident, from spiraling out of control. So now, quietly, they're preparing for a confrontation.
"This is where the accident – God forbid – would more likely occur," Air Force Secretary Deborah James says of the Baltic region, an area of critical importance to NATO and where it abuts Russia. Commonly called the alliance's "northern flank," the three Nordic countries beget military activity frequently due to their geography, instilling in them the need for greater cooperation with the West both to train their forces and to determine how they could synchronize their activities in the event of an actual conflict.
