Re: Did the Klingons destroy Romulus in Abrams Star Trek?
Klingon and Romulan spaces are very close to each other.
Hobus doesn't have to be in the part of Romulan space which is closest to Klingon space. Nimoy's narration didn't mention, say, Kronos getting destroyed or threatened with destruction. It doesn't give the impression that Klingon space and Romulan space were facing equally imminent doom and Spock just chose to try to save Romulus arbitrarily.
Just walk away, and there will be an end to the horror.
