The answer is no. The dispute settlement mechanisms in NAFTA will continue operating as they have. Both countries will still be able to call upon those mechanisms, as you've seen quite recently in the way the corn dispute was resolved.
On chapter 7, with Darfur, there has been dialogue at the United Nations with a number of countries on who would be able to commit forces, who is in a position to commit support personnel who would be able to advise on technology, communications, training of soldiers, and the logistics requirements. There has been active discussion on those aspects of it.
On the specific commitment of military personnel in the form of combatants, peacekeepers, that may have been discussed. I'm not familiar with that, since my responsibilities don't extend to the United Nations. I do know there have been discussions on those earlier matters that I just referred to.
