I tend to agree, Christopher
, that the Typhon Pact poses a new challange - more of a competitor than an enemy (at least for now).
BUT, in order for TrekLit to provide readers with drama and conflict on a galactic scale (at least IMO), the TP needs to be used as something other than an ally. Not an outright enemy bent on the UFP's destruction, as that would be "more of the same" in regards to the last two major conflicts (the Dominion and the Borg), but as a counterpoint.
I can totally get behind stories that deal with a "Cold War" between spheres of influence, an economic rivalry or an ideological ones, "fought" on various fronts, without erupting into a full scale armed onflict (I have total faith that the writers and editors will try to present the current situation in an original way
All in all, I think that the change (establishment of the TP) is for the worse, as far as the Federation is concerned
, which is exactly as it should be (no point in having a new series called Star Trek: Golden Age
, now is there?
