While in some sense I share the desire both on this thread and the Cardassian one that there had been a more philosophically coherent opposition to "Federation values" among the main aliens (compare the BSG Cylons, who were allowed to be "right" about many things by that franchise's in-universe standards), the (perhaps unfortunate) reality is that the great majority of canon Trek was just not written that way. Probably that's part of the Roddenberry-ish "message": Cold War Americans and Russians really aren't any "different"; they've just by the whims of history ended up with different and opposed forms of government, and if you take that away and put them in a situation where they have to get to know one another they find that they have a ton of things in common.
Perhaps this message is unrealistic by real-world standards, and certainly many other SF/F systems bake in more deep-seated differences than did Trek, especially post 9-11 SF/F (although I suspect that particular fad might have run its course). And canon of course is not a straightjacket that strictly binds all subsequent fiction for all eternity. But I for one am not quite willing to just rewrite things (at least in the Prime continuity) that were consistently and clearly portrayed over many episodes and films — as was the depiction of Romulans fearful of their government and willing to oppose it and defect from it — just because it happens to be more in line with 2009 storytelling).
(But hey, that's why we got a reboot timeline, right?)
