Volume 105 of Terrorism: Commentary on Security Documents ("Narco-Terrorism") brings researchers up to date on U.S. and international efforts to stem terrorism related to drug trafficking. In the pages of this volume, readers will find both legal documents from criminal cases againstnarco-terrorists and governmental reports on how to approach the problem on a broader level. After showing recent trends in combating narco-terrorism globally, Volume 105 focuses on the rising drug crises in Colombia and Afghanistan. Researchers will find in this volume not just U.S. agencies'major reports on international drug-trafficking but also similarly comprehensive reports from international organizations, from NGOs to the U.N. These reports place a particular focus on the connection between terrorist activity and the global narcotics trade. The section on Colombia, whileupdating readers on the international struggle with that country's drug cartels, also includes an analysis of the political, diplomatic, and economic challenges in intervening there. The Afghanistan portion of the volume shows how the U.S. has tried to confront the heroin trade that has funded theTaliban there, including an example of how the U.S. government has used criminal prosecutions domestically to curb that trade.
