If Poland (or other NATO land) is attacked in the future by some Russian ill-fated adventure/military exercise, it will be an existential attack on NATO, which will then gut the Post-Soviet advance.
Italy, Spain, France, UK, Sweden, Finland, Turkey, Germany, Greece, Denmark (last two have decent air power), have the means... (wait for it)...
This is one reason why Ukraine must never be added to NATO, IMHO
