of Québec nationalism. He admired the labour unions, which were tied to the Cooperative Commonwealth Federation (CCF), and tried to infuse his Liberal party with some of their reformist zeal. By the late 1950s Trudeau began to reject social democratic and labour parties, arguing that they should put their narrow goals aside and join forces with Liberals to fight for democracy first. In economic theory he was influenced by professors Joseph Schumpeter and John Kenneth Galbraith while he was at Harvard. In 1963, Trudeau criticized the Liberal Party of Lester Pearson when it supported arming Bomarc missiles in Canada with nuclear warheads. Trudeau was offered a position at Queen's University teaching political science by James Corry, who later became principal of Queen's, but turned it down because he preferred to teach in Quebec. Early political career (1965–1967) In 1965, Trudeau joined the Liberal party, along with his friends Gérard Pelletier and Jean Marchand. Dubbed the "three wise men" by the media, they ran successfully for the Liberals in the 1965 election. Trudeau himself was elected in the safe Liberal riding of Mount Royal, in Montreal. He would hold this seat until his retirement from politics in 1984, winning each election with large majorities. His decision to join the Liberal Party of Canada rather than the CCF's successor, the New Democratic Party (NDP) was partly based on his belief that the federal NDP could not achieve power. He also doubted the feasibility of the centralizing policies of the party. He felt that the party leadership tended toward a "deux nations" approach he could not support. Upon arrival in Ottawa, Trudeau was appointed as Prime Minister Lester Pearson's parliamentary secretary, and spent much of the next year travelling abroad, representing Canada at international meetings and bodies, including the United Nations. In 1967, he was appointed to Pearson's cabinet as minister of justice and attorney general. Minister of justice and attorney general (1967–1968) As minister of justice and attorney general, Trudeau was responsible for introducing the landmark Criminal Law Amendment Act, an omnibus bill whose provisions included, among other things, the decriminalization of homosexual acts between consenting adults, new gun ownership restrictions and the legalization of contraception, abortion and lotteries, as well as the authorization of breathalyzer tests on suspected drunk drivers. Trudeau famously defended the segment of the bill decriminalizing homosexual acts by telling reporters that "there's no place for the state
