Really wish FASA's take on Klingons and "The Final Reflection" novella were the canon versions. Along with the simple idea of an Enterprise class heavy cruiser, rather than saying the film Enterprise is still a Constitution.
With Discovery wrapping up season one I'm finally looking to run a TOS campaign. With the Klingon Front now so ridiculously big, time to consider how to work Axanar in. Major wars don't have just one decisive battle. (Though I have a feeling the final episode of Discovery is going to show me wrong.)
Again, the "Four Years War" is specific to FASA continuity, where it was indeed four years long (give or take a few months).
The phrase has never been used in canon, and definitely not in relation to the war in Discovery.
I have seen a nice variation where the conflict aborted by the Organians was known as the Four Minute War (or Four Day if you allow for the build-up).
@Kevin: I hope you weren't too disappointed! Still not sure how to fit Discovery into my canon yet. The relations with the Klingons are quite important, but I don't like the Disco interpretation - and I'm not sure how quickly Starfleet could have recovered from that level of destruction in 10 years... Although I guess TOS could be considered post-apocalypse? Maybe this even explains the tech?
The fleet losses from Discovery actually line up quite nicely with the sense of isolation and independent action in TOS - there aren't many ships around, so a Captain has to make do without expectation of relief or assistance. Personally, I really like that as a rationale for why there seem to be so few starships in TOS, and why the Enterprise seemed to stop in on every colony and outpost it came across: Starfleet is spread thin as it recovers from war losses.

"Post-apocalypse" then :) It would explain the "there are only twelve like it in the fleet" remark...
They did seem pretty keen to get back at it by The Organian Incident! Presumably, this is the same rationale that led to the arms build-up last century - which is a good parallel given the "cold war" referenced by a lot of materials.
