From the Summary: "Recent debate on U.S. policy toward Colombia has taken place in a context of concern for the volume of drugs readily available in the United States and elsewhere in the world, and security issues in the Andean region. The United States has made a significant commitment of funds and material support to help Colombia and the Andean region fight drug trafficking since the development of Plan Colombia in 1999. […] President Alvaro Uribe, re-elected in May 2006, is seeking to address the 40- year plus conflict with the country's leftist guerrilla organizations, as well as the rightist paramilitary groups that have been active since the 1980s. President Uribe enjoys high levels of popular support, though his second term has been marred by scandal. Parties loyal to President Alvaro Uribe dominated the March 2006 congressional elections. U.S. policy in Colombia remains controversial. Proponents of current U.S. policy point to inroads that have been made with regard to the eradication of illicit drug crops and improved security conditions. However, nongovernmental organizations argue that U.S. policy does not rigorously promote human rights, provide for sustainable economic alternatives for drug crop farmers, and has not reduced the amount of drugs available in the United States. Congress has expressed concern about a number of Colombia-related policy issues including the aerial eradication of illicit drug crops, interdiction programs, the situation of U.S. hostages, funding levels for Plan Colombia, and human rights."
