Appeasement in Science Fiction

I recently finished another BSG episode, in the Eastern Alliance story arc. As is typical in the old BSG, the tone is anti-appeasement. Anti-appeasement sci-fi themes are fairly common. V condemned appeasement, as did an episode of Babylon 5. Even relatively sophisticated takes on fascism (Genesis of the Daleks, for instance) and warmongering tend to view appeasement as a de facto bad. Obviously, this viewpoint stems from Neville Chamberlain's tragic missteps with Hitler. Yet, I am not sure how wise it is to always portray appeasement as evil. There have been times where acts of appeasement could have alleviated much suffering - for instance, in Saddam's Iraq. Other times, anti-appeasement rhetoric is used against regimes that have been more wronged by the U.S. than we have been by them. For instance, anti-appeasement rhetoric is commonly used against Cuba, which had quite reasonable fears for its safety during the 50's and 60's (U.S. involvement in Cuba is a rather sordid tale of coup-making and imperialism, for those who don't know). The theme of appeasement is interesting in the original BSG, because it contrasts rather sharply with several episodes in the series that promoted pascifistic politics. Apparently, BSG wanted to have its cake and eat it too. But I think the show's rather naive faith in the military (a faith that sometimes the modern BSG seems to share), ultimately limits its success when compared to non-military oriented shows, like Blake's 7, Firefly, and Farscape, which can take far more critical views of government and politics, and still get away with it.
