As a politician in Canada, Liberal Leader Michael Ignatieff has said that he was on the sidelines of the Iraq war, but new information reveals he was on the front lines of pre-invasion planning when he worked in the U.S.The article Lilley has written goes on to describe how Pentagon and Air Force leaders worked with the Carr Centre for Human Rights, including work done by Michael Ignatieff, to, erm, find out how to limit civilian casualties. This was part of the US military's plans to try and bring in some outside opinion from such notable centres as the Carr Centre, NGO's, and media heads to figure out exactly how the Iraq War was going to play out, and how the Americans could win the PR battle (they didn't, fyi).
Ignatieff — long known to be a supporter of the decision to invade — was part of an academic advisory team that helped U.S. state department and American military officials conduct strategy sessions.
I don't know about Lilley, but this doesn't sound like "frontline" work to me, nor does it even sound like any Pentagon officials actually had personal contact with Ignatieff, but instead used his work, which was prolific at the time. The way the Sun is attempting to portray this, it's like Ignatieff was in Washington DC pointing out when and where to start bombing - not how to protect civilians.
To further point out, that was the only thing of notable substance in this article - the rest of it was pure waste and filler, designed to make it look like a bigger issue than it actually is. We don't need a primer on the Iraq War, Brian - if you had a point to make, you should have made it. Not wasted space.
