An up-to-date examination of Mexico's version of the "War on Drugs" that exposes the evolution of major cartels and their corruption of politicians, law-enforcement agencies, and the Army. What can President Enrique Pena Nieto do to curb the narcotics-induced mayhem in Mexico, and what would be the consequences to the United States if he fails? This book analyzes Mexico's transition from a relatively peaceful kleptocracy controlled by the Tammany-Hall style Institutional Revolutionary Party/PRI (1929-2000) to a country plagued by rural and urban enclaves of grotesque violence. The author examines the major drug cartels and their success in infiltrating American and Mexican businesses; details the response from the Obama administration; assesses the threat that the continuing bloodshed represents for the United States; and emphasizes the constraints on America's ability to solve Mexico's crisis, despite U.S. contributions of intelligence, military equipment, training, and diplomatic support. Documents the origins of Mexico's drug industry to explain today's situation involving a graft-ridden Army, suborned police, ruthless capos, unethical office-holders, and U.S. security forces Emphasizes the threat that the widespread criminality represents to the United States, as well as the constraints on Washington's ability to solve its neighbor's crisis Exposes the linkages between elected officials, particularly governors, and the underworld Illustrates the challenges that will remain, even if the cartels were shattered, by the presence of a human infrastructure of 500,000 men, women, and children skilled in kidnapping, extortion, torture, murder for hire, human smuggling, and dozens of other crimes
