If the time frame, post-apocalyptic or dystopian future, is omitted the presumed time frame is the present. And then your protagonist is immediately guilty by temporal association with current events, with terrorist incidents like the Boston bombings.

Good luck getting a warm receptive to your logline and pitch. You’re going to need it — and then some.

I suggest that if the story is set in a dystopian future, then say so in the logline. Yes, that’s 4 extra words, but the alternative guilt by temporal association factor is a far worse problem to confront than 4 extra words.

Unless, of course, you really do want to make an explicit, direct political statement about the current U.S. government and military. If that is the case, well, good luck getting a warm receptive to your logline and pitch. You’re going to need it — and then some.
