I see that Blair claims that he would have gone to war anyway, irrespective of WMD.
He claims that he could have presented the rationale for the war without the WMD.
Funny he didn't make that case then at the time.
Could it be that he knew full well that the excuse of WMD (whether they existed or not) would be the only way to persuade the British people to back his private war?
In other words he knew that his "rationale" for war would not stand up to scrutiny.
