I think this is all a bit of an irrelevant academic discussion. If Russia were to cross into Poland, it would essentially pit the world against Russia.
If you're on board with the article and believe Putin is on a historically motivated crusade of sorts, and of sound mind, it's difficult to imagine he'd initiate an invasion he has no chance of winning.
The fact that Poland can't muster an armed force as sizeable as Russia's is entirely beside the point in this scenario, especially considering he would be pitting his now somewhat depleted military resources against all of NATO, and potentially even more.
