Yep; Russia going into a civil war is the best time for the people Russia has stolen land from to retake their territories.Funny thing about a russian civil war, China has historical claims on russian far east territory, and that territory is rich in resources. Japan has historical claims on that big island in the Pacific and it has a buch of resources on it Japn desperately needs. So if Russia goes into civil war there are a bunch of deals that can be made that will be to their perminant detrement.
I also expect Russian nuke officers will likely become effective kingmakers/warlords once the fighting sets in.
