John Key hasn't spoken up yet. As for David Cunliffe, he's just been asked about it by Newstalk ZB's Felix Marwick. His response is pure mush:
Cunliffe on troops to Iraq: wd dep' on the circumstances when request made. Won't hypothesize what answer wd be w/out having specific facts.And there you have it: David Cunliffe ain't no Helen Clark. If you want New Zealand to stay out of America's stupid wars, you'll need to vote for someone else.
a difficult decision and would rely on the position taken by the United Nations and our partners. Can't rule anything in or out.
Update: And meanwhile, John Key says the chances of his government contributing to any intervention are "remote". Its a sad day when Labour looks more warmongering than National.
