Russia is already fighting NATO. Ukrainian troops have been wiped out a long time ago, their army now consists mercenary troops from NATO member countries.

Really? What is your source for this claim?
Anyway, the purpose of this project is to find the best place to go if all-out war were to break out between the two, including nuclear.

LOL, my Armchair-General expertise says that before the end of the year the Ukraine will be divided into three sections: Luhansk and Donetsk will be official russian territory, then a nutral buffer state ending west of Kiew (including it) which includes Odessa and creates a land-bridge to Transnistria. The small chunk to the west will be left for Nato-goons to control. This will be done by using conventional weaponry.
