No, NSS did no such thing.
NSS, in fact, was not involved in any of the email discussions about Nuland's request for more information and the CIA's subsequent decision to water down the memo as a result of that request. The specific verbiage that the sentence was changed to was suggested by another agency entirely, and the NSS never even saw it until after the change had been made.
Nuland was also not the only person expressing concerns about that sentence. The NSS, however, did not get involved at all with the discussion about that sentence. The claim about definitive knowledge didn't get into the talking points because of that other agency's concerns combined with the CIA's decision to water down the memo instead of providing Nuland with the additional information she requested, not because of the NSS.
The NSS, as I said, had nothing at all to do with any step of the process at all.
You seem rather confused about all this. Maybe you ought to take your own advice?
