If the rysskies want to populate that area, all they need to do is sell plots of land to "The Long Dark IRL" survivalist types. The ones who don't make it through winter can sell their plot back at a discount and it can then be resold to the next rube. Eventually you'll have a population of self reliant, hardy types who will become russified over time.

Putin has also been busy with re-activating the stronk Russian presence in the Russian Arctic, and the Laptev Sea. Nagurskoye in Franz Josef Land was refurbished recently, and they are building new bases at the New Siberian Islands, and Wrangel Island.
These places were in some cases totally abandoned following the Soviet collapse (they were broke), and are only just now being explored again in a military capacity.
There was apparently some sort of US claim on Wrangel Island at some point (and a few hard-line US patriotic blogs have mentioned it), but even if so, it has long since been abandoned in any serious sense.

We don't. Even the guys doing the taking knew it and got out through Vladivostok.
