All western countries are susceptible to right wing populist grifts because they basically all run on the same (social-) media platforms and are manipulated following the exact same playbook.

But at least from the outside Poland doesn’t look like the prime candidate. After all they already had (and later rejected) their insane populist goverment constantly rambling about war with their neighbour. And at least looking at the polls they don’t seem to be rebounding from their loss.
