One thing about Kirk as Admiral. While most hold that he is a Rear Admiral (either a renamed rank of Commadore, or a two star Admiral), but he holds the position of Chief of Starfleet Operations. If that is like the US Navy's Chief of Naval Operations, that is a full Admirals job. A top admiral's job. Fleet Admiral if you have one. This is the senior military officer of the Department of the Navy. If that translates to Starfleet, than Kirk was promoted a lot from Captain and someone thinks he can do the job, with Nogura being either the Secretary of the Navy, or the admiral in charge of Earth's fleet (or just the deployment of the Constitutions).
When you put it that way, I'm wondering if there's a Vice Chief of Starfleet Operations who's actually doing the bulk of the work instead of Kirk, since he's so bored with the cushy desk job.
Also, full admiral in two years makes nuKirk's promotion less unbelievable now. "How many cliffs do I have to hang from to get THAT job? Sign me up!"
