I'll go a step further: Not only is the evidence and history of US-Taliban relations all still there, but the accused-1984 people weren't even denying the history exists. They were, at worst, just glossing over it.
Let's suppose that there are five tiers on the spectrum of "good" to "1984": Acknowledge the history; Omit it; Contradict it, Erase it, Punish dissenters.
Prior to 2016 most US politicians never went past Omit.
The whole point of the 1984 scenario was that people couldn't talk about the preceding period and no evidence supporting its existence could be found.
