That’s a good point. Plus, that would make the whole concept of the Sequels less cynical - not so much “everything our OT heroes worked for failed because they’re bad at their job,” and more that “They succeeded for a time, but eventually the First Order stole their victory.” I think the key would be to somehow establish both that everything has been grand, but also that the First Order wants to do away with it. In under 100 words.

The galaxy is in crisis.
Luke Skywalker, working
to restore the legendary
Jedi Order, has vanished.

Peace dissolves into chaos,
and Imperial sympathizers
begin rising in power.
Declaring the Republic to
be broken and inept,
they demand a return
to the FIRST ORDER
of the Empire.

While the Senate stalls,
a few determined members
secretly form a daring
RESISTANCE to the threat.
They pursue a lead to the
Last Jedi’s whereabouts,
believing that Luke can
end the Imperial threat
once and for all…

It would also work to add “While the Senate stalls, [desperate to avoid war]” to the last paragraph; but that puts you at ten lines, and I think the other lines are all more important to the setup…
