Martin confused over Iraq?

In last night's debate, on the issue of sending Canadian troops to Iraq, Paul Martin insisted that he had never suggested doing this nor even considered it. Stephen Harper quoted a page from the former American ambassador's book that stated otherwise. Later in the evening, the Liberals issued a press release claiming that Stephen Harper was lying - yet the press release quoted the section from Celluci's book stating that Paul Martin had in fact contemplated sending Canadian troops to Iraq (so, in essence, they confirmed Stephen Harper's point rather than making one of their own). News release and quotes from the book and the debate at Inkless Wells.

(addendum - Liberals later tried to clarify, via Inkless Wells again, that they were differentiating between the initial invasion of Iraq and sending troops afterwards, I'm not sure most Canadians really care about the difference).

(Oh, and I was trying to be a dutiful citizen last night by watching the debate - even played "Give 'Em the Boot Bingo" - I wish that "fundamentally" was on the card multiple times because Martin certainly says it a lot!)
