Foreign Policy Decision Making: The Case of Canada and Nuclear Weapons

Foreign policy decision making is the result of a complex political process in which the political values and style of the chief executive play a large part. The case of Canada's decision, in 1963, to acquire nuclear weapons illustrates that external events and pressures generated by Canada's international obligations were processed through complex political interactions. The Government of Prime Minister Diefenbaker was unable to take the nuclear weapons decision because of two splits in the Cabinet, only one of which was pertinent to nuclear weapons policy. The decision was taken by Leader of the Opposition Pearson alone and in conformity with his personal values, because of his political style which commanded deference. The approach used combines historical detail with political analysis.
