The fallback argument was WMD, bring democracy and prosperity.
Instead we got ISIS.
I was very surprised that this was released as it adds to the evidence that the decision to attack Iraq and to dismantle its security services was based on lies and deception.
The timing of the release, when the repercussions of creating political and military instability in the region are becoming more frequent in Europe and the US is what surprises me the most. Perhaps the US has reduced its energy dependence on the middle east sufficiently to begin focusing on Saudi Arabia?
With this release and the Chilcot report, the leaders of US/UK have created a serious deficit in credibility and trust.
