Ever since NATO's intervention made itself seriously felt, Russian media has basically portrayed the war as a war between Russia and NATO (and with good cause, because Russia really is fighting NATO-trained and equipped Ukrainian troops alongside Western mercenaries). Russian social media aggressively posts videos and photos of Western volunteers. If there is a facing-saving exit ramp for the Russian command, the fact that Russia is taking on the 'entire West', and not just the scrappy little country next-door, surely qualifies.
