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.

It is lose-lose situation for everybody.

Nobody in EU, USA or China is interested in Russia winning the war because that would embolden them to further expand east to Moldova and Baltics.

And nobody in EU, USA or China is interested in Russia losing the war because that could turn into fracturing of Russia and civil war inside Russia with nukes.

Putin got Russia into impossible situation which will end badly either way.
