Until the thargoids either clear off or surrender I say we keep firing.
Heck I'd go on a diplomatic escort mission to talk peace with the bugs, but with gun ports open and all 6 advanced plasma chargers fully loaded.
But I remember who started this war... ripped out of witchspace and fired on without mercy, we gained a respite from them for a while, then they came back again, I'm sure they had the technical means to talk to us if they wanted but didn't and I was there at the Oracle on that night
And 1000's died, I remember making run after run with my Asp's cargo hold jammed with refugees hoping the bugs would not catch me.
They wanted a fight, and we've given them a fight and by god I wont rest until every last stinking thargoid is ejected out of our space.
Because every time I encounter a thargoid and open the gunports I shout
"REMEMBER THE ORACLE"

The first people pulled out of Witchspace were let go peacefully. It was only after people were caught with stolen tech that the Thargoids attacked.
