The NSS Newsline is usually a pretty good source of information which is why I'm not immediately dismissing this article
as being nothing more than a conspiracy theory.
What they are suggesting is that Blair's enthusiasm for the invasion of Iraq was inspired by a belief, shared with Bush, that the invasion was a “holy mission” and "a fulfilment of Biblical prophecy".
Personally, I don't think any lasting settlement is going to be reached in the Middle East until the various religious groups - each with their own agenda - can be pushed out of the picture. If there is any truth in the NSS claim, however, Blair's Faith Foundation is a religious group that needs to be further from the Middle East than most.
