Kaliningrad will as the main military base..
My feeling is that they'd try to avoid Kaliningrad due to its proximity to Poland and elsewhere.
If the yanks do it, it'll probably be a military base near Kabarovsk, if we do it, it'll be a base in the North but trying to avoid ecological damage, and if the French do it, it could be anywhere
course, if RuSSists strike our cities, then Moscow and St Petersburg will be next.
Experts say there are three steps of escalation over two days. The third step? No russia left apart from savage peasants in Siberia.
