I would like to throw a caveat in the discussion. Given Simon Peggs recent comments about the canon of the "Kelvin Timeline" http://simonpegg.net/2016/07/11/a-word-about-canon/ Quoting Simon Pegg:"Spock’s incursion from the Prime Universe created a multidimensional reality shift. The rift in space/time created an entirely new reality in all directions, top to bottom, from the Big Bang to the end of everything. As such this reality was, is and always will be subtly different from the Prime Universe. "
A lot of fans are assuming that what happened to the Franklin in regard to the ship missing, also happened in the Prime Timeline. Neros incursion did not just impact the present, it also impacted the past of that universe. We saw that in the Next Generation episode "Yesterday's Enterprise". When that ship came forward in time it altered the past as well as the present creating a generation of Starfleet Officers who knew nothing but war with the Klingons. The Xindi and Romulan conflicts were perhaps radically different from the original Timeline in the Kelvin TImeline. I have never heard the Xindi incident referred to as a war. I don't think that was an accident.Perhaps in the 'Kelvin Timeline' Earth responded with military force as opposed to sending a lone ship into the Expanse. It is suggested that Kralls experiences in both wars were very personal. Krall became Captain of the Franklin in 2161 which is the same year the Federation was founded. It is suggested that the Federation was founded and entrenched prior to his transfer. If you go back to Into Darkness, they were vague about the Eugenics Wars suggesting it took place during a 'World War'.
I think fans spend a lot of time trying to reconcile the prime and kelvin timelines but it may be time to stop doing that and accept that the Kelvin Timeline including past and present events are going to be radically different. If you watch all three films you will see that there is a clear divergence and it runs in two directions.
