Course Description
One hundred years ago, a Canadian diplomat in Washington wrote a confidential memorandum for the Canadian Government on relations with the United States, outlining the questions that may lead to friction. That list of issues was remarkably prescient and has defined the Canada-US agenda to the present day, though the specific details have varied. Managing the relationship with the United States has long been the most important element in Canadian foreign policy, and there is a surprising continuity of themes. From environmental issues to trade and investment disputes, continental and global defence relations to cultural sovereignty, the same types of issues keep appearing on the agenda. Participants will discover how today’s headlines echo the issues faced by previous generations, and how much is the same and how much is new in today’s challenges posed by Donald Trump’s United States.
