A land-grab in the ocean? The Battle of Ellesmere Island?
I think there's about as much chance of having a small arms conflict in the Arctic as there is of Putin invading Greenland riding a polar bear. What exactly do you envision? Canadian troops invading Novaya Zemlya? The Arctic is unpopulated in a way that is difficult to describe. There is no one to shoot, and even getting there is a huge logistical problem. I'm pretty sure you've never been to the Arctic, but for the sake of argument, is there any basis to these ideas of yours?
It's when reading things like this that I miss the Cold War
CFS Alert, on the northern tip if Ellesmere Island is an intelligence station (COMINT & SIGINT). I had two tours there, 6 months each, during the lat '70s.
During my 2nd tour, we had a base defense exercise. The scenario (such as it was), was that for some strange reason, the Soviets decided to drop a regiment of paratroopers to attack the base while the Bears flew overhead to rain nuclear destruction on North America. Our mission was to defend the base - specifically, the operations building - long enough to destroy all the classified material contained therein.
We were freaking squints, not frikking pongos
Too bad they also discovered that it would take us 3-4 weeks to destory all the classified material
