Hm let's see, you got a neighbouring country as your enemy which is not only the worlds largest and one of the largest weapons manufacturers, but also can strike you 24/7 with cruise missiles and drones, which you can't stop.
Your infrastructure is destroyed, you are out of heat and power. Your airspace is closed. Winter is coming. Your allies in the west are getting tired of supporting you. You have already lost a large percentage of your fighting age males.

Yeah. Sounds like a totally guaranteed win!
