Pearson and Canada's Role in Nuclear Disarmament and Arms Control Negotiations, 1945-1957

Lester Pearson was Minister for External Affairs between 1948 and 1957. During this time Canada was a member of two successive United Nations commissions on eliminating or controlling nuclear arms with the United States and the Soviet Union as the main negotiators. The goal of these discussions was to reach an agreement on general principles that reflected the strategic needs of each side, rather than on the technical details necessary for a treaty. While the United States and the Soviet Union played the largest role in the negotiations, two other major powers, Britain and France, allies of the Americans, were also at the bargaining table. Canada was the only middle power to participate in all negotiations.
