Whenever you really want to show how bad a baddie can be to everyone, have Earth be in danger, if not under direct attack.
Strange why TWOK worked.
Don't think that Earth wasn't in danger. Khan had himself a weapon of mass destruction that could destroy an entire planet. No world in the Federation was safe, not even Earth.

Orci and Kurtzman wanted Khan from the very beginning...
According to an interview at startrek.com re-posted at our own TrekToday, they didn't, but producer Damon Lindelof did.
“[Damon Lindelof] argued for Khan from the beginning and I argued against it,” said Orci.
Orci and Kurtzman compromised with Lindelof; they initially wrote the story without Khan and then found a way to insert him in later.
