It relates to 1939 more than it does 2017. Trump is running an authoritarian administration, no doubt about it, but we're not quite at the stage yet where such a plot points to USA 2017. Maybe if the film went deeper, but as it is there's not much there that directly relates to what Trump is doing today. Also, everything you just described was a part of the original trilogy too. Civil War & Zootopia had more to say about our current political climate than Rogue One.
And I meant Star Trek in general. I thought that was obvious...
