I've grumbled about this before, but why stop now?
I'd suggest some backstory for General Korrd. After all, his assertion of dormant authority supplies the resolution to the crisis.
All we see of him in the film shows him as drunk and useless, and his sudden influence comes out of left field.
Have a scene wherein Spock consults the ship's computer (stock footage would work) for background on Korrd. This permits us to see (newly filmed) flashbacks depicting someone who was once hailed as a great statesman and reluctant warrior, but whose capabilities have since deteriorated.
Of course, Spock will remember this at the ciitical moment.
