This. Can you explain this?
Certainly.
Don't you think we'll be utterly exhausted
I wouldn't say utterly but, yes, you will be exhausted. You won't stop with Ukraine though--that wouldn't make sense. You will come back to your old demands of NATO withdrawing behind the Oder river and will want to run things (or at least influence them heavily) in Poland again. We can't have that. You also explained to me some time ago that the wheels of anti-Polish propaganda are turning so strongly that Russia doesn't even have any sensible offer for us (commensurate to our value and potential). We hear either threats or insults from Moscow; threats don't scare us, insults don't touch us, but it all puts us in this damn zugzwang. We have no option left really.
So, going back to this coming war between us -- the time would come when Ukraine falls, then after about 3 years of передышка (and maybe not even that), you will become a serious threat to Poland again. When the war comes we will have to fight on Polish land. In such case, we cannot very well start defending at the borders because you have panzer/artillery army, and you artillery would massacre us. We observe this war with caution and we can see that you have good technical/engineering capabilites but, first and foremost, excellent artillery. Sure, we are buying artillery like crazy but still we must assume that we would be at a disadvantage here, especially that we would have to concentrate huge numbers of artillery, practically all of HIMARS etc. to be able to blow Kaliningrad off the face of the earth as a response to your nuclear attack against one of our cities. In general, we could probably sustain 5-6 big nuclear strikes and still keep fighting but here comes the entire question of escalation ladder and possible NATO response but I don't want to go into detail on this. I mentioned it cursorily before, it's a complicated issue. Luckily for us, where you lead decisively in artillery, we lead decisively in infantry; our infantry is poetic and legendary and the defence of towns and cities that we would put up would amaze the world. Plus we have good electronic reconnaisance/drone capabilites which would give us a lot of advantage.
So, we would have to do pretty much what Ukrainians do (according to, without bragging, our ANW blueprint) but - unfortunately - we lack their strategic depth. That's a huge bummer. Germany might act as our deep strategic background but history and the aching pain in our anuses taught us valuable lessons, so for the purpose of my scenario I assume 0% NATO reaction and 0% USA reaction. We would have to fight alone. Our chances? If we are honest, I'd say 40-45%. If NATO/US decide to react at a higher rate than 0%, then of course our chances rise, but I'm not counting on that.
Russia's mistake, I believe, was that you attacked too early. You should have kept trading with the EU, exert huge influence on European matters, get rich, strengthen you armed forces and wait for about 20-30 years more until guys like me are either dead or no longer fit for military service. Then you could walk over the young snowflakes with much ease. Alas, for you, we are still here and still in a rather good shape.
Sorry, if it's all a bit chaotic. I'm an amateur strategist - I bet the professionals are thinking like crazy and have something much better in their drawers. They most likely do, seeing that PAD had the temerity to tell Putin not to sh*t himself ha ha ;)
it is incorrect to say that the West is our enemy
Yes, but you don't consider Poland to be part of the West - курица не птица, польша нет заграница, and all that.
