It all adds up and Sweden has lots to give, they make HQ modern weapons systems and have lots of spare artillery now that Russia is on the ropes, and they will join NATO or will end up defended by it anyway if Russia should attack them, through Finland. Norway also has a lot of bucks to throw around defending Finland and Sweden would definitely be in their interest. If the Russian army should ever get back on its feet it would first have to deal with Ukraine and by then with post war prosperity, oil money and a strong military culture armed to the fucking teeth with the most modern weapons, they would be a real piece of work. Also, by then Germany would have a big very powerful army, then there's also Poland...
I think Russia's imperial days are over, the only way they can get on their feet is to get out from under sanctions and that will require regime change and more, much more. If they don't reform, they will have a half a million half-starved conscripts on the border carrying shields and fucking spears staring at the lights of a prosperous European Ukraine and wondering WTF they are living like shit.
