 Why is Retief being sent to Jorgenson's Worlds?

Since they've met no opposition so far in their infiltration of Terrestrial space, they intend to seize Jorgensen's Worlds by force." Magnan leaned back, waiting for Retief's reaction. Retief drew carefully on his cigar and looked at Magnan. Unfortunately, Jorgensen's Worlds are technologically undeveloped areas.
