Having followed Mexico's cartels for years, border security expert Sylvia Longmire takes us deep into the heart of their world to witness a dangerous underground that will do whatever it takes to deliver drugs to a willing audience of American consumers. The cartels have grown increasingly bold in recent years, building submarines to move up the coast of Central America and digging elaborate tunnels that both move drugs north and carry cash and U.S. high-powered assault weapons back to fuel the drug war. Channeling her long experience working on border issues, Longmire brings to life the very real threat of Mexican cartels operating not just along the southwest border, but deep inside every corner of the United States. She also offers real solutions to the critical problems facing Mexico and the United States, including programs to deter youth in Mexico from joining the cartels and changing drug laws on both sides of the border.

One of the most surprising developments in Mexico's transition to democracy is the outbreak of criminal wars and large-scale criminal violence. Why did Mexican drug cartels go to war as the country transitioned away from one-party rule? And why have criminal wars proliferated as democracy has consolidated and elections have become more competitive subnationally? In Votes, Drugs, and Violence, Guillermo Trejo and Sandra Ley develop a political theory of criminal violence in weak democracies that elucidates how democratic politics and the fragmentation of power fundamentally shape cartels' incentives for war and peace. Drawing on in-depth case studies and statistical analysis spanning more than two decades and multiple levels of government, Trejo and Ley show that electoral competition and partisan conflict were key drivers of the outbreak of Mexico's crime wars, the intensification of violence, and the expansion of war and violence to the spheres of local politics and civil society.

This text explains the punitive trend in Mexican anti-drug policies as a political imperative, an out-growth of the perceived need both to counter the growth of the illegal drug market and to prevent US police and judicial authorities from acting as a surrogate justice system in Mexico.

Postmodern global terrorist groups engage sovereign nations asymmetrically with prolonged, sustained campaigns driven by ideology. Increasingly, transnational criminal organizations operate with sophistication previously only found in multinational corporations. Unfortunately, both of these entities can now effectively hide and morph, keeping law e
