Just to assume all the spoiler stuff is true...
Wouldn't it make more sense for the Romulans to attempt to travel back in time and kill Spock than Kirk? Spock was the key to the success of the theft of the original cloaking device. Spock was responsible outing Valeris and foiling the Klingon/Romulan/Fed assassination plot. It is Spock who is causing waves of dissent on Romulus and threatening to spread reunification propoganda.
Off Spock.
