West Africa is under attack from international criminal networks that are using the subregion as a key global hub for the distribution, wholesale, and increased production of illicit drugs. Most drug trade in West Africa involves cocaine sold in Europe, although heroin is also trafficked to the United States, and the subregion is becoming an export base for amphetamines and their precursors, mainly for East Asian markets and, increasingly, the United States. The most important of these criminal networks are drug trafficking organizations (DTOs) from Latin America-primarily from Colombia, Venezuela, and Mexico-partnering with West African criminals. These criminals, particularly Nigerians and Ghanaians, have been involved in the global drug trade for several decades, first with cannabis and later with heroin. The problem has worsened to the point that these networks represent an existential threat to the viability of already fragile states in West Africa as independent, rule of law based entities. As part of this new Latin America- West Africa criminal nexus, Guinea-Bissau is generally recognized as a narco-state where state-capture by traffickers has already occurred. There is also increasingly strong evidence linking terrorist organizations or state sponsors of terrorism to the West Africa drug trade, including Colombia's Revolutionary Armed Forces of Colombia (FARC), al-Qaeda in the Islamic Maghreb (AQIM), Hezbollah (allied with elements in the Lebanese diaspora), Venezuela, and Iran. These criminal and terrorist groups are also a threat to U.S. national security, because the illicit profits earned by Latin American drug cartels operating in West Africa strengthen the same crimi nal elements that traffic drugs to North America, and the same North African and Middle Eastern terrorist groups and nations that target the United States. The link to AQIM takes on particular significance in light of this terrorist organization's recent takeover of a vast sector of ungoverned space in northern Mali, along with Touareg allies. West Africa's geographical location between Latin America and Europe made it an ideal transit zone for exploitation by powerful drug cartels and terrorist organizations-much as the Caribbean and Central America had long suffered for being placed between South America's cocaine producers and North America's cocaine users. West Africa's primary operational allure to traffickers is not actually geography, however, but rather its low standards of governance, low levels of law enforcement capacity, and high rates of corruption. Latin American traffickers recently relocated a share of their wholesale distribution from the Western Hemisphere to West Africa, with the subregion moving from being merely a short-term transit point to becoming a storage and staging area for wholesale repackaging, re-routing and sometimes (re-)sale of drugs.
