America’s new national security strategy doctrine is getting a lot of attention and for good reason. Two main points stick out for Rudyard and Janice: the assumption that Europe is a civilization in decline, and that the western hemisphere belongs to the United States. Up until this point, many of us accepted that in the last decade the world has shifted considerably with the rise of China. The post-Cold war unipolar period led by America as the superpower is over and we are witnessing a return to the great power competition between countries that defined the late 19th and early 20th centuries. What should concern Canadians in the strategy announced last week is the notion of spheres of influence, which suggests that North America belongs to the U.S. who will dominate and discipline neighbouring countries. Putin praised the doctrine which also implies that the other great powers – specifically China and Russia – are allowed their own spheres of influence. How should Canadians interpret this strategy? And how should it inform our foreign policy and defense strategy in the years ahead?
