I'm somewhat curious: Could the Temporal Cold War, as shown in numerous episodes of Enterprise, have altered any historical events previously shown in TOS, TNG, DS9 and VOY? According to Trek author Christopher Bennett (and assuming I understand him correctly), if time travel from the future results in changes made to the past, those changes are only carried through to the era the time travel originated in if the time travelers return to their era, or information travels from the altered past to the future in some manner. Basically, I wonder if a lot of what we saw in ENT originally applied to the stuff set later in time.
