Input: Article: Though much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force. It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents; Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. Similarly, Ferguson did not believe citizens built the state, rather polities grew out of social development. In his 1767 An Essay on the History of Civil Society, Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.

Input: Article: Pentecostalism eventually spawned hundreds of new denominations, including large groups such as the Assemblies of God and the Church of God in Christ, both in the United States and elsewhere. There are over 279 million Pentecostals worldwide, and the movement is growing in many parts of the world, especially the global South. Since the 1960s, Pentecostalism has increasingly gained acceptance from other Christian traditions, and Pentecostal beliefs concerning Spirit baptism and spiritual gifts have been embraced by non-Pentecostal Christians in Protestant and Catholic churches through the Charismatic Movement. Together, Pentecostal and Charismatic Christianity numbers over 500 million adherents.

Input: Article: On 18 June 1948, the National Security Council issued Directive 10/2 calling for covert action against the USSR, and granting the authority to carry out covert operations against "hostile foreign states or groups" that could, if needed, be denied by the U.S. government. To this end, the Office of Policy Coordination was created inside the new CIA. The OPC was quite unique; Frank Wisner, the head of the OPC, answered not to the CIA Director, but to the secretaries of defense, state, and the NSC, and the OPC's actions were a secret even from the head of the CIA. Most CIA stations had two station chiefs, one working for the OSO, and one working for the OPC.

Now answer this question: In what year was directive 10/2 issued?

Output:
1948
