The collective turning away of heads (of both the Irish state and the majority of its citizens) that Werner refers to in relation to Shannon is hypocritical.
Those that believed that the case for war was not justified and whose views have now been vindicated are not being hypocritical. We are just happy that the tooth, the whole tooth and nothing but the tooth has finally emerged.
The inquiry found many errors in the lead up to the invasion. In attempting to somehow exonerate Bliar, DOM picks just one of these errors and points the blame elsewhere. In so doing, he is engaging in exactly the same type of selectivity that Mr. Bliar adopted with such disastrous consequences.
In any event, in relation to the WMD bit, Chilcot lays the blame on MI6. The spies over-promised about their ability to gather reliable intelligence. The agency realised that one of its key sources was a fabricator even before the invasion, but Chilcot says MI6 kept this concealed not just from the public, but also from Bliar.
However, and importantly, the inquiry also found that Bliar had been given warnings, including from senior members of his own staff, that much of the intelligence seemed dodgy and did not support a case that Saddam was an imminent threat. His culpability, in this particular regard, was to use his trademark evangelism to represent the bogus intelligence as compelling evidence that Saddam was a real, present and growing danger when he was not.
Again it's worth repeating that this was just one of the failings identified by Chilcot.
