From the time that President Ronald Reagan declared war on drugs in 1982 through today, the United States increased the military's role in interdiction and made illegal drugs a central component of U.S. foreign policy. Despite these actions, international drug trafficking has become the world's largest criminal enterprise and the United States is far and away the number one market for illegal drugs.This book sees the so-called war on drugs as a failure that has actually contributed to a growth in the drug trade. An overview of the U.S. antidrug policy is first provided, followed by an in-depth examination of the major criminal organizations that have been involved in trafficking, focusing on how these so-called hard targets got started, their organizational structure, their operations and how law enforcement worldwide has responded to their growth. The social, political and economic effects of drug trafficking are then explored. A concluding section assesses the impact of U.S. policy on the worldwide drug trade and puts forth what has been learned from this failed agenda.
