You're including countries like Luxembourg, Slovakia, Slovenia, Denmark, Montenegro, Croatia etc. Once Russia announced its new military doctrine, the Croatian president immediately said they wanted no part of this and has made sure to reiterate those sentiments weekly, just to make sure his country gets spare if or when ish hits the fan.Well sure Russia can conquer Germany but they cannot defeat the whole of the NATO alliance (excluding USA). There is 31 countries in NATO excluding USA. No way Russia can beat 31 countries. It took Russia 3 years to gain only 20% of the territory of Ukraine.
That said, in my opinion, no one would come out of a war with Russia with victorious. Everyone would lose. Australia would end up being the last fully intact "western" country.
Regarding the territory, 8.3 million Ukrainians are ethnic Russia. Therefore, there's no way Russia can just steamroll the country without significant backlash back home. This whole reasoning could of course just be a smart excuse designed to hide Russia's military ineptitude. We'll, hopefully, never have to find out.
