I doubt anyone in Poland seriously considers partition a possibility. But a certain lack of consistency from the Allies during WWII might still rankle among those old enough to remember the aftermath.

Not that the UK and US were ever likely to declare war on Russia immediately after. It was considered as an option, but rejected for obvious reasons.

But there's a case to be made for mismanagement of the invasion in 1944, which added another 6-12 months to the war and allowed the Soviet incursion into Europe to push far to the West of where it might have reached otherwise.
