I'm going to ask a question of Mr. Shea. I will be in touch with him off-line about a particularly jarring remark in his opening presentation; I don't want to focus on that now.
You mentioned the concept of red lines for things like chemical weapons, and you talked about a role for Canada in advancing some norms on arms control.
Could you say a bit more about both the role of NATO in establishing some red lines with the new nuclear threats that we have with tactical weapons, and the idea of NATO pursuing some more activity in the area of arms control?
