On the other hand, it confuses me to see everyone defending Kirk's decision to blow up the Enterprise 1701 in Search for Spock... While you're focussing on the tactical necessity of the destruction as a way of fighting against the Klingons, you seem to have forgotten he stole the ship in the first place, and wasn't on a Starfleet sanctioned mission to begin with?
But if he doesn't show up, no one knows what happens to Grissom
and one of the key developers of the Genesis device gets taken back to the Klingon Empire never to be heard from again.
If I was Starfleet, I'd want to sweep Kirk's actions under the rug as quickly and quietly as possible. His actions exposed Starfleet's total ineptitude in the matter.
