True, if the planet is destroyed because they are so desperate to stop a devastating war. A war that is never mentioned again in the TOS era or any era, that plot does not make your eyesEh, I dunno. Destroying part of Florida and then never mentioning it again is certainly bad, but we're talking about something on the order of 1000 times more casualties if Qo'noS is destroyed.

(Real life WW1 celebrations will take place this year 100 years later, all if not most of the veterans are RIP. There are retcons and then there are things that make you go 'What are these writers smoking'!!!!!!)
