The final explanatory feature important to the Taliban's insurgency as a greed-based rebellion is the influence of a previous rebellion. With the support of the CIA and ISI the young Taliban in the 1990s were pitted against the Soviet Union in proxy war. This enabled the Taliban to do a number of things. They became involved in opium trade, were provided with weapons, and began to construct the organizational aptitude that allows for their continued success today. The previous involvement of the Taliban in an armed insurgency allows one of the issues with a greed-based insurgency to be dismissed. Collier and Hoeffler assert that the government has an innate advantage in greed-based conflicts as the government is more organized. However, in the case of the Afghan conflict this is not true. The transitional government is more fractionalized, less cooperative, and more ethnically divided than the Taliban. Therefore, using the greed-model we should actually expect the Taliban to defeat the transitional government after NATO's withdrawal, as the government possesses few advantages. This case shows the explanatory power of the greed model, enabling a better understanding of what the variables look like in the real world. In the Afghan case there haven't been many successes in peace building. As the following section will illustrate, the greed model is not without holes or needed additions, but the Taliban insurgency can definitively be characterized as an actor motivated primarily by the conditions that foster the greed model. Sri Lanka is an island country in South Asia that suffered from a violent civil war for more than 25 years. The fighting took place between the majority of the Buddhist Sinhalese population and the minority Hindu Tamils. This brief case study will demonstrate how the civil war was caused by horizontal inequalities and how it therefore supports the 'grievance' argument. Injustices can be seen across different ethnic groups. When the people from a certain ethnic group perceive that they are being given less opportunities by the government simply because they belong to that ethnic group, in terms of education and economy for example, it creates grievances. These grievances, which are called horizontal inequalities, lead to violent conflict. The war that took place in Sri Lanka was due to the perceived grievances that the Tamil population experienced during Sinhalese rule. Sri Lanka–-then called Ceylon–was under British colonial rule from 1815 to 1948. Even though the majority of the population was Buddhist Sinhalese, with over three million people, the British people favored the Hindu Tamils, which accounted to 300,000 people. The Tamil population therefore enjoyed privileged access to education and to government employment.
