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.
