Si vis pacem, para bellum

Si vis pacem, para bellum is the title of the eighth episode of Star Trek: Discovery. It premiered on the 5th of November 2017 on CBS All Access and one day later worldwide on Netflix. This episode was shown during a promotional fan screening organized by Netflix in London on 5th of November.

The title is a quote from Cicero, meaning: If you want peace, prepare battle. When translating this to Klingon, do not use ghuH, because that means "prepare for war", which is something else than preparing a war.


On mission at the planet Pahvo, the USS Discovery crew discovers a new species with unique communication skills. Admiral Cornwell is trying to escape the Klingons. L'Rell wants to overrun Starfleet, which Kol sees through.
