The answer to your question is YES - it is flatly untrue that "Wilson Insisted The Vice-President's office Sent Him To Niger," and that the quoted statements support such a claim.
You seem to be completely missing the point. The issue is whether Cheney (or his office) sent him or someone within CIA sent him. It is clearly the latter, and Wilson has never claimed otherwise.
At the behest of the VP's office--which gave him "credibility" because he was not on some partisan maneuver--which he clearly was.
You are picking at the tiniest, most inconsequential elements of this for the sake of some weird argument.
Wilson was attempting to imply that he was an "insider"--he has said most of his friends are Republicans, he supported the first Gulf War, etc. And that what led to him going to Niger was the VP's office--OBVIOUSLY implying that the VP believed in him.
You don't get that? You don't see that Wilson was trying to say--without explicitly saying it--"Hey, I'm no hack--I'm an INSIDER who innocently went ot Niger and found out the Administration was WRONG! And they ignored me, ME! And insider sent by the VP's office!"
If you are so easily duped, good luck to you--you have a hard life ahead. But the rest of us who can think know what someone is trying to do with language. Or are you going to argue that Wilson is some innocent who doesn't understand diplo-speak?
Go ahead and be willingly duped, for whatever reason you want to believe Wilson. But your whole argument here is a prissy obsession about the phrasing of a subject line, whereas the actual item is 100% true by your own admission.
