For decades now, the South American nation of Colombia has remained in a state of perpetual civil conflict. The Colombian government is entrenched in a war against leftist guerillas and right-wing paramilitaries. In 2000, the Clinton administration approved a $1.3 billion program entitled Plan Colombia. This program was primarily aimed at crippling the illegal narcotics industry that is responsible for producing the majority of cocaine that arrives in the United States. Other goals of the plan included improving the Colombian economy, preventing human rights abuses, establishing a more consistent and secure judicial system, and increasing the overall legitimacy of the Colombian government. The purpose of this research has been to examine the level of effectiveness of Plan Colombia. Through literature analysis and through interviews with Colombians living in the United States, I have attempted to determine the degree to which the United States has accomplished these goals. The sources for the literature analysis include government documents and policy analysis pieces. The interviews were designed to get the perspective of Colombians on this situation. I have determined that perhaps the best answer to whether or not the plan has been successful is that there is no “yes” or “no” answer. Aspects of the plan are working, however the degree of their effectiveness is contested, In the meantime, Plan Colombia is expected to last for many more years, so it is important to understand which efforts are making a difference.
