Good evening Brits Why are the Poles so forgiving towards y'all?

Surely they must know how you Brits go on and on how the yanks were late coming to your aid, they must know that you signed two mutual defence treaties with them ,before WW 2,then they were invaded and y'all did nothing and left them hang out to dry for almost five years and in fact allied with one of the nations that invaded them [USSR] Surely they know how y'all take credit for breaking the German code when it was a Pole who did that. But yet they show no anger over this. Why y'all think that is?
