The original attacks on both Kiev and Kherson were obviously meant to be coups de main, depending on subverted leadership and a collapse in morale. It came off in Kherson but failed in Kiev.
Shock and awe on Poland will be entirely the other way. Russian forces have shown their incompetence and incoherence, and technological backwardness besides. Fighting on two fronts, vs Poland (and all its allies), will moreover put the Russian army under impossible strain.
There won’t be Polish allies involved. The war against Poland won’t be as restricted in terms of collateral damage as you see in Ukraine.
