Thank you, Mr. Chair, and to our guests for being here today and taking the time to present to the committee.
Mr. Clarkson, maybe I'll start with you. As I was hearing your comments, I was nodding my head, particularly around the comments on the war on terror and how that needs to be re-examined. I think that's already happening in Washington, thankfully. Some of the measures we've taken remind me of the Maginot Line. We set up and put in billions of dollars, and it has not necessarily been to the greatest effect. Others will say, no, it's kept us safe. I'm not sure; the jury is out on that. If it's to challenge that, as you say, to shift the paradigm, we need a win.
When we look at NAFTA there have been problems, as you've stated, and perhaps Mr. McRae might challenge that a bit, in terms of “we've got it, so use it”. But if we're looking for a win in terms of, at least, bilateral--and maybe I'll talk about Mexico in a minute--we've had them in the past. The most recent, clear win was when we dealt with acid rain. It was an activist government. It was a Conservative government. When we look at that model, would it not behoove us to really get engaged on the environment? Cap and trade is the model that's being presented to us. If not that file, then which file would it be, in your opinion?
