Russia, and all of the countrys that have full time military ataches in there command structure are not interested in loosing this conflict, as it represents the future of security and military actions. Accepting a pause or temporary truce is meaningless as 'violations' have become the norm, and as financial and other restrictions remain while further offensive capacity is fielded, it only creates a false sense of security for there population, so they will fight now. The attack on the gas going to China from Siberia, is exactly that, and will prove to be a very serious misscalculation.
