I think the question of middle-power leadership is a problematic one, mainly because in Canada there is a reluctance to embrace the ideas of middle-power leadership in those particular terms.
As Colin suggested, even if we don't talk about middle powers any longer—and Canadian leaders don't like to talk about middle powers—the essence of trying to find positions that will garner support from other like-minded states is critical.
This, it seems to me, means that we have to have a large-scale effort on the part of Canadian diplomats and Canadian politicians, both on the government and the opposition sides, to press the ideas that we have embraced so readily over the last 70 years or so as Canadians to remind others, to remind Americans, of the positive aspects of that order.
