It is not required nor is it material as to whether Wilson is completely honest or not.
It is a documented fact that Wilson helped expose the Niger yellowcake lies. It is undisputed that these were lies with faked documents.
It is also documented that Cheney was very angry with Wilson's actions.
The fact that Wilson's opinion on why Libby's sentence has been commuted co-incides with mine has nothing to do with his honesty. It is a logical interpretation of the available facts.
Incidentally when Henry II got pretty angry about a certain detractor he did penance by walking barefoot in a rough woollen robe to the scene of his crime and was flogged by the monks.
An appropriate punishment would be to flog Cheney on the steps of Congress.
But it seems that the checks and balances in place in 21st Century America are less strong than on Medieval Kings of England.
