No I don't think there was anything substantial in it. We know there wasn't, now.
But at the time, Plame didn't know that-the CIA didn't know it (according to them).
So I think it's very relevant to ask, WHY didn't Plame make sure Wilson's report was given attention?
Wasn't that the whole point of going, to find out one way or the other? He made a conclusion, came back with it, and his own wife, who sent him on the trip---disregarded it.
NOBODY CARED. Why? His own wife didn't care what his findings were, to the degree that his oral report was never conveyed to any other levels.
Yet Wilson claims he went around Washington trying to get "the administration" to take note of it. Why would they, if Plame and the CIA didn't think it important?
