It was originally a civil war triggered by the struggles of different tribes and factions in Libya. Later, due to the intervention of western countries, it developed into an international war between western countries and the Middle East and North Africa. The cause of the unrest in Libya is generally believed to be mainly due to the autocratic rule of President Gaddafi and the recent wave of protests sweeping the Middle East. But in fact, the division that the country is falling into is still deeply rooted. The Libyan war is the fourth time that the military alliance led by western countries launched a large-scale military attack on sovereign countries after the Kosovo war in the 1990s, the Afghanistan war and the Iraq war in this century. The Great Socialist People's Libyan Arab Jamahiriya, referred to as Libya, is a North African country. Located on the southern bank of the Mediterranean, bordering Egypt, Sudan, Chad, Niger, Algeria and Tunisia. Except for coastal areas and southern mountainous areas, most parts of the country are deserts. Libya has an important strategic position and is an oil-producing country, which once made it an important trading partner of European countries. However, because its government opposes western hegemonism, it is politically excluded by western countries. Since 2003, Libya has actively improved its relations with European and American countries and reached many important understandings. At present, the UN sanctions against Libya have been lifted. It is generally believed that the unrest in this country is mainly due to the autocratic rule of President Gaddafi and the recent wave of protests sweeping the Middle East. But in fact, the division that the country is falling into is still deeply rooted. Libya was once a colony of Italy. During the Italian colonial rule, Libya was composed of three autonomous states. The eastern region and Benghazi are basically autonomous. According to The Wall Street Journal, after Gaddafi came to power in the military coup of 1969, he achieved national reunification by force. He also moved the capital to Tripoli and shifted Libya's political focus to the west. Its regime has largely ignored the east, although most of Libya's oil wealth is there. According to the report, Gaddafi used tribal disputes to maintain his rule to a certain extent and promoted his tribe to key security positions and decision-making positions. He also successfully suppressed the growth of other political power centers by reorganizing the whole government regularly, making potential political opponents lose their support base or prestige. As a symbol of his Islamic revolutionary ideology, he also nationalized all private enterprises in the 1980s. Reuters commented that Gaddafi's 40-year leadership over Libya has not made this country a people's country. On the contrary, Libya is one of the countries with the most serious corruption problems in the world. As a country that produces 2% of the world's crude oil, the oil wealth created by Libya has not benefited its 6 million people. According to Libyan insiders, Gaddafi's own tribe controlled some armed forces, and it took them several years to destroy the base of his rival Warfalla. Valfara was once considered as the largest tribal alliance in the country, but this is a thing of the past. Now, when Libya's political loyalty is severely tested, many tribes left out or oppressed by Gaddafi are against him. Several tribal leaders in Valfara have appeared a few days ago, calling on the people to overthrow Gaddafi. The "Al-Zawiya" tribe from eastern Libya also joined the demonstrators over the weekend, and a leader once threatened to cut off vital oil supplies if Gaddafi remained in power. In fact, the possibility of persistent conflict and civil war has sounded the alarm for the global oil market, and the international oil price has jumped to the highest level in more than two years. According to foreign analysis, the turmoil in Libya will affect the economy of the whole Mediterranean region, and Italy, as its former colonial ruler, will bear the brunt. At present, Libyan Interior Minister Abdi and Justice Minister Ali have announced their resignations from the government led by Gaddafi. Abdi called on the army to support the opposition and fulfill its "legal obligations as citizens". In addition, at least seven Libyan ambassadors resigned to protest the killings at home, and some senior diplomats called on Gaddafi to step down.
