Mark of Gideon (TOS) as well.
And how do the Gideons feed all of their people? You'd think alot of them would have starved to death.
Starfleet has the perfect solution to Gideon's overpopulation problem. Starships. You got too many people. Move em to another planet or planets.
Memo to Starfleet: There's these newfangled devices called cameras with telephoto lenses. Put some on your starships so that they can passively scan a planet's surface from orbit. That way the Gideon idiots wouldn't know about it.
Some good quotes from this episode that are timely even now.
"Clearly the purpose of diplomacy is to prolong a crisis."
