By the power of truth, I, while living, have conquered the universe.

There's a new library on 04b though, and one would assume a new index as a result. I know John wanted to rescue Cortana, but surely the logical military decision would have been to retrieve the library's index and destroy High Charity via glassing or orbital bombardment, rather than send one man in on a suicide mission to recover an AI who may or may not be corrupted on the hope she still retained the index's imprint.
Yeah, a new Index was being fabricated but Guilty Spark said that "it will take time" at the end of The Covenant. We're not given much of an indication as to how much time this is exactly, but Spark expected Installation 04B to take "a few more days" before it could be properly fired - in this time it's highly likely that the Flood would have overrun the entire Ring and the Ark.
