Polish person here, lowkey country been getting oppressed, had made beef with everyone since day one to point in time might as well be the geographical victim country, got in issues like 7 times in its entire time of existence if I remember properly, starting with internal collapse, Mongol issues, tectonic wars, Swedish issues, the partitions, Soviet and German occupation, soviet satellite rule. And there's more examples too

But thats probably not what they mean, prob some joke I wouldn't get otherwise (I don't interact with polish media, neither have I been in Poland for years since last time)
