We have also not seen the best of Russian stuff till now and no mobilisation which you guys should be shit scared of. Russia can now over run all the old Warsaw pact countries as they have no weapons to defend themselves. Their equipment has been sent to Ukraine. The NATO countries are themselves short of missiles and other equipment to fight Russia. All you will be left will be just rifles. Your so called air power will become easy meat for S-400, Can you explain to me why have you not enforced no fly zone over ukraine? what stops you if you have such overwhelming air power?
Russians are fighting in areas which has a population of their own. Their hands are tied. But will that be the case when they attack Poland or Hungery or Germany? Think over.
German 6th Army for whom Hitler had said can win heavens for him was humiliated and the only surrender of an Field Martial ever in the history of modern warfare of Puolus was done before red Army. Learn from History. RA now has your finest whom you sent to support neo Nazies of Mariapul in their custody.
We've seen their cruise missiles (Kalibur, R-500, Kh-101, P-800, Kh-22/32), their Iskander-M etc. Russia has not seen what NATO stand-off weapons can do.
As regards overrunning Europe, Poland's military compares equally to Ukraine's.

And if Russia invades a NATO country, they will get saturated with cruise missiles and air power, and not just in that area, we will hit Moscow and everywhere inside Russia, and if they fire nukes, we will obliterate them and any of their allies just as a precaution.
Russia's IADS has already failed miserably, even without NATO jamming, MALDs, ARMs, cruise missiles, PrSM and stealth aircraft. It's a joke now, especially after the Moskva.
Because it wouldn't just be a NFZ, it would have to be a SEAD/DEAD operation first, which means directly attacking Russian ground forces whether they fly or not. That likely means escalation.
Their hands are not tied, but they should be in handcuffs. After several village massacres, mass deportation and rape/child rape, and flattening several towns, Odessa, and Mariupol, you cannot claim they are being careful, or even trying. Sorry.
How will Russian forces and logistics (supplies) even get to Poland? Teleportation. They'll get shit-raped in bulk by sensor-fused munitions before they even reach Ukraine if they pick a war with NATO. Then you'll have the world's longest 40 mile traffic jam, because all the vehicles will be toast and it will take them weeks just to unblock the road.
You might find warfare has changed since 1945, but even then USSR received a lot of help from western allies, including planes, probably too much. They couldn't even build jet engines until they stole designs from the British.
