Im a fan of the Star Wars movies and your quote seems incorrect. I'm sure it should be:

"Princess Leia, before your execution I would like you to join me at a ceremony that will make this battle station operational. No star system will dare oppose the Emperor now."

Leia: "The more you tighten you grip Tarken*, the more star systems will slip through your fingers."

*Grand Moff Tarkin was the Imperial governor of the Outland Regions, and a key figure in the development of the Death Star project.
