prices on world markets increased considerably, leading to the accumulation of substantial funds in Libya, as a supplier of oil to western countries. Government revenues from oil exports were to be used to finance urban development and the creation of a modern system of social welfare. At the same time, to improve Libya's international prestige, huge sums were spent on creating a well-equipped modern army. In the Middle East and North Africa, Libya served as a carrier of ideas of Arab nationalism and as an uncompromising enemy of Israel and the United States. The sharp drop in oil prices in mid-1980s and the UN sanctions for harbouring Palestinian separatists (in 1992) led to a significant weakening of Libya. On 12 September 2003 UN Security Council lifted the sanctions imposed in 1992. Public aspect of the theory The third part—the "Public aspect of the Third International Theory" was published on 1 June 1979. This addressed many aspects of life, including women, the education system, sports, and merging the world's languages. In this part a global vision of proper co-existence is presented. The fundamental principles come down to this: every nation should have its own religion, and should recognize the importance of a continuous social chain ("the family—the tribe—the nation—the world," "from the small to the great"). According to the "Green Book": "if the national spirit is stronger than the religious spirit, the struggle between different nations, which used to be united in one religion, is amplified, and each of those nations achieves independence, returning to the social structure that is characteristic of it." "A tribe is the same as a family, but one that has increased due to the increased growth of offspring, that is, the tribe is a big family. The Nation is a tribe, but a tribe that has grown as a result of increased offspring, i.e., a nation is a large tribe. The World is a nation but a nation divided into many nations as a result of population growth, i.e., the world is a great nation." "The tribe is the natural social protection of the individual, ensuring his social needs." In Libya, according to accepted social tradition, the tribe collectively provides redemption of its members by collectively paying ransom for them, paying their fines, avenging them and collectively defending them. A special place in the Green Book is reserved for women, their physical build and social role
