The actions of india on May 18, 1974 reinforced the fears of forecasters of horizontal proliferation of nuclear weapons. The Indian detonation of a nuclear device gave tremendous credence to the "Nth" power theory, but more importantly revealed the inadequacy of moral suasion and the need for only peaceful uses of nuclear energy as the basis for nuclear non-proliferation. Since Canada had co-operated with India in the construction of the CIRUS reactor from which the plutonium for the Indian explosion was produced, much attention has been focused upon Canadian actions in co-operation and transfer of nuclear energy technology. The impetus provided by the action of India has produced an insistence by Canada and other nuclear energy suppliers for stricter safeguards to avoid further state action in obtaining nuclear explosive capability.
