I'm not worried about that because, historically, Canada-U.S. relations have been compartmentalized. Defence-related issues only affect defence. The Americans' presence on Canadian soil during the Second World War and the excellent level of cooperation in that regard didn't necessarily mean Canada's resources were in jeopardy. The different spheres of activity have always operated in silos. Historically, those kinds of activities in the security realm have not led to losses like the ones you are referring to. Canadians must do their part, to be sure. However, I'm not concerned about the consequences of a closer working relationship with the Americans, provided it follows well-defined parameters and explicitly drawn up rules.
