Actually, a common misconception. Not only is Russia the coldest-in-the-world country, but it's also the one which houses most of uninhabitable territories. "Hiding" in Siberia without massive financial support and investment is impossible. Dying there? Damn sure. Most of Russia's lands are so bad that they only justify oil extraction and are totally unsuitable for human life otherwise. The european part of Russia harbored most of it's population.Russia is a big country, there's plenty of room hide in.

Your map was a bit too large and was messing up my formatting (and therefore other people's as well), so I linked to it.
