I always felt that the DS9 relationships between Cardassians & Bajorans was a product of the time when the show was written, and had stronger overtones of the 1990s Balkans conflicts and Israel/Palestine than anything else. (Though it’s far from a direct allegory for either)

You also had The Troubles in Northern-Ireland at the time, and that's not a huge leap either.

I've also seen people describe the Bajorans as an analogue for the Jewish diaspora.

You can fit many real-life events, even more if you try hard enough.
