Well, what we saw in "These are the Voyages" was a historical reconstruction, devised decades after the fact, and probably originally based on second and thirdhand data. Hell, they even got the date wrong (Riker's simulation is set in 2161; seven years after the "Terra Prime" incident, and after the Romulan War).
I find it fully possible that it's what Riker believes happened.
That's the only way I can choke it down.
Or you can think of TATV as an alternate universe episode. Considering that absolutely EVERYTHING looked completely off in that episode, simply declaring it AU would have been entirely reasonable, IMO.
I'm such a Trek Omnivore and to my chagrin I have ended up loving all sorts of Trek things I hated first time round.. Vic Fontaine comes to mind here. When I watched TATV the second time following my second all-the-way-through viewing of ENT I fully expected to like it because I seem to warm up to everything. I hated it SO MUCH.. even more than the first viewing. It is really a complete piece of crap.
And as this thread points out, easy to dismiss because it's from Riker's perspective, limited by history and who-knows-what. And the novels do in fact tweak some of what happened with good explanations as to the tweaking.. but how much better to have just skipped it.
