Quite a few readers are coming to the rescue, offering another interpretation:

I have to say that I always considered the Bajorans to be, in the allegory, the Jews (and, to a lesser degree, the French) and the Cardassians plain old Nazis. The Cardies certainly never had a history of being oppressed themselves that would be required for the other allegory to work at all. I don’t see anyone for the Palestinian role at all, although there was one episode where a group of people supposedly related to the Bajorans showed up from the other side of the wormhole and tried to assert a right to return. But those guys weren’t seen again after they were sent packing. Additionally, the Maquis colonists are very close analogs to Israeli settlers…which puts the Cardassians in the Palestinian role, there, and the Federation as Israel proper. But there’s only so far you can stretch an allegory.
