Aedh-
As I alluded to in my post above, most Science Fiction - and especially Star Trek - is often a metaphor for the zeitgeist of the culture that produces it. (Look at all of the “Cold War” plotlines in TOS Trek.)
Note that this is neither positive nor negative. Sometimes this can be good, reflecting the hopes, dreams, and aspirations of a culture. Sometimes it can be bad, showing the fears, prejudices, and hatreds of a culture; one particularly egregious example is the 1930’s “Flash Gordon’s” “Ming the Merciless,” a thinly veiled metaphor for the “Yellow Peril” anti-Asian prejudice of the times.
I wonder if my earlier posts about the “far future of the Federation” are just a reflection of my worries and fears about the future of the United States? Does my viewpoint show up my fear of the "Ugly American factor," the censorship of “political correctness,” the increasing bureaucratization of the government, and the erosion of personal freedoms imposed by technology?
Also; I always considered the Bajor/Cardassia situation of DS9 to be a metaphor for the Middle East – the clashes of religions, the Arab/Israeli/Palestinian situation, the “wormhole” as a metaphor for oil (a newly discovered invaluable resource focuses superpower attention on a previously neglected backwater)…
