Above these remained Gaddafi and the RCC, who remained responsible for all major decisions. In crossing regional and tribal identities, the committee system aided national integration and centralization and tightened Gaddafi's control over the state and administrative apparatus. In June 1973, Gaddafi created a political ideology as a basis for the Popular Revolution: Third International Theory. This approach regarded both the US and the Soviet Union as imperialist and thus rejected Western capitalism as well as Eastern bloc communism's atheism. In this respect, it was similar to the Three Worlds Theory developed by China's political leader Mao Zedong. As part of this theory, Gaddafi praised nationalism as a progressive force and advocated the creation of a pan-Arab state which would lead the Islamic and Third Worlds against imperialism. Gaddafi saw Islam as having a key role in this ideology, calling for an Islamic revival that returned to the origins of the Qur'an, rejecting scholarly interpretations and the Hadith; in doing so, he angered many Libyan clerics. During 1973 and 1974, his government deepened the legal reliance on "sharia", for instance by introducing flogging as punishment for those convicted of adultery or homosexual activity. Gaddafi summarized Third International Theory in three short volumes published between 1975 and 1979, collectively known as "The Green Book". Volume one was devoted to the issue of democracy, outlining the flaws of representative systems in favour of direct, participatory GPCs. The second dealt with Gaddafi's beliefs regarding socialism, while the third explored social issues regarding the family and the tribe. While the first two volumes advocated radical reform, the third adopted a socially conservative stance, proclaiming that while men and women were equal, they were biologically designed for different roles in life. During the years that followed, Gaddafists adopted quotes from "The Green Book", such as "Representation is Fraud", as slogans. Meanwhile, in September 1975, Gaddafi implemented further measures to increase popular mobilization, introducing objectives to improve the relationship between the Councils and the ASU. In 1975, Gaddafi's government declared a state monopoly on foreign trade. Its increasingly radical reforms, coupled with the large amount of oil revenue being spent on foreign causes, generated discontent in Libya, particularly among the country's merchant class. In 1974, Libya saw its first civilian attack on Gaddafi's government when a Benghazi army building was bombed. Much of the opposition centred around RCC member Omar Mehishi. With fellow RCC member Bashir Saghir al-Hawaadi, he began plotting a coup against Gaddafi. In 1975, their plot was exposed and the pair fled into exile, receiving asylum from Sadat's Egypt.
