On January 3, 1963, NATO Supreme Commander General Lauris Norstad visited Ottawa, in one of a series of visits to member nations prior to his retirement. At a news conference, Norstad stated that if Canada did not accept nuclear weapons, it would not be fulfilling its commitments to NATO. Newspapers across Canada criticized Diefenbaker, who was convinced the statement was part of a plot by Kennedy to bring down his government. Although the Liberals had been previously indecisive on the question of nuclear weapons, on January 12, Pearson made a speech stating that the government should live up to its commitments.
