Well, at least Kimmel and Short (General, not Admiral) are going to have better endings to their careers than OTL; granted, Pearl was still attacked, but, while still awful, it wasn't as bad as OTL (and they weren't caught by surprise), so they'll end their careers somewhat better ITTL. They're still going to be relieved; they were in charge at Pearl Harbor, and someone has to take the fall for that, but they'll have better reputations ITTL...
I am not so sure they either deserve or will be relieved. They implemented the War Warning. They were on alert with the radar operating and sighting the incoming raid. They did not have enough fighters to defeat the attack but they were not responsible for the number of fighters they had. They used what they had pretty well.
