Ivanova's quip to Sheridan about going "where everyone has gone before" while the Ministry of Peace political officer Julie Musante was trying to seduce him, was a direct poke of fun at the opening narration of Star Trek (1966) which includes the phrase "where no man has gone before" and also references Captain Kirk's tendency to have romantic relationships throughout the series.
The term "Ministry of Peace" was first used in George Orwell's 1948 novel '1984', where it was the name of the War Ministry. Abbreviated in Newspeak as "MiniPax", it co-existed with ministries for propaganda (Ministry of Truth, or MiniTrue), rationing (Ministry of Plenty, or MiniPlenty) and secret police (Ministry of Love, or MiniLuv).
