Strangely enough, it was only on fifth viewing that I expressly realized that Nero obtained the red matter to destroy Vulcan from Spock Prime's Jellyfish ship.
This raises the question as to why Spock Prime, after he realized he was to be captured by the Narada, did not at once ignite or disable the red matter (perhaps by jettisoning it).
It might be suggested that the Jellyfish was purely scientific, without autodestruct capabilities. In fact, however, we know from its destruction of the drill to Earth that it had weapons capabilities, so its designers must have had in mind that it might be attacked and captured.
In a sense it is Spock Prime who is responsible for the destruction of Vulcan, because it was he who failed to safeguard the red matter adequately, allowing it to be stolen.
