Russia missed a chance to bleed America in Afghanistan for 20 years. Yes, there was supposed to be some support given to the Taliban but, being a regional power, a LOT more could have been done by Russia to hurt America in Afghanistan. Also, if Russia decides to make the war too forbidding for the West even right now, it could arm various anti-Israel forces with lethality never seen before. It will be a regional war but it will end one way or another soon because Israel's American backers wouldn't put up with blood spilling in Israel.
Having said this... observing something is not the same as wishing something. I'd rather this war be over asap.
