The tide has turned, though ofc there do exist more complex options. For example, in case of partial defeat in the Ukraine, Russia might rebound inside its proper borders (incl. ofc Crimea) and successfully encyst, like Iran after war against Iraq, largely senseless and played to draw. This war has a honking big chance to become forever-cindering conflict, because only through warfare both the Ukraine and Russia could now stave off their internal entropic disturbances.
