Short answer - the Poles hate the Russians and the Russians have nobody to blame but themselves on this.
The problem with Russia is that the Russians are in denial on this.
And Poland’s problem 85 years ago was that they trusted England and France that they would fight for them. The lack of French/English invasion into Germany in September 1939 speaks volumes on how the Poles got this wrong and as a result around half their buildings and 20% of their people died in the next 5.5 years before the Russians occupies them for the next 44 years.
Poland’s problem today is that they trust the USA to defend them now. I can think of at least 34.2 trillion reasons why that would not be a good idea for them to be so trusting.
You mention trust.
What happened is that Hitler and Stalin took advantage of supremely confident diplomat dupes that believed in the infallibility of the diplomatic machinations.
