<P>Mexico has failed to achieve internal security and poses a serious threat to its neighbors. This volume takes us inside the Mexican state to explain the failure there, but also reaches out to assess the impact of Mexico's security failure beyond its borders.

This tightly organized volume begins to correct that gap.</P>
