I was quite sure from the very beginning that this conflict will end peacefully without firing a single bullet because war between two major world powers is out of question in the context of Nuclear weapons both of them are carrying. I am not in favor of Nuclear weapons but lesson of history after WW2 is that Nuclear deterrent has successfully prevented major war between the big world powers.
The battle ground makes Russia more vulnerable than for USA, beside this will look like an Ukrainians war than USA war that has always been Russian enemy. I used to think Nuclear weapon are no more allowed in war by NATO because of the radioactive effect on health in a long while
