So were the Irish. But allegory to Palestinians works, too, I suppose. The thing with the Palestinians is that both Israelis and Palestinians can equally say they have an ancient claim, and it was the UN that created Israel. In fact, you go back far enough, virtually everyone was taken over by another group at some point. SO saying any one group is an allegory should be stated in loose terms. Add me to the list. The Romulans were almost uneasy allies with the Federation. Had DS9 aired even longer, or a show that followed the events of DS9 happened, instead of Enterprise, we might have seen the beginnings of a Federation\Klingon\romulan alliance. That would have been interesting. Too bad it won't happen.
