A Boko Haram massacre in a northeastern Nigerian village last month captured world-wide attention as it was reported that the terrorists burned children alive.

Far less reported are credible allegations that a key source of funding for Boko Haram and other Islamic extremists is cocaine, produced and exported by the Revolutionary Armed Forces of Colombia (FARC) and other drug-smuggling cartels working in concert with the Bolivian government. This is the same FARC supposedly negotiating a peace agreement with Colombian President Juan Manuel Santos—an agreement that would derail its drug-trade gravy train.

Europe’s recreational drug users like cocaine. European and U.K. drug warriors thought they could curb the availability of the white powder by cracking down on South American supply lines. But the cocaine capos have shifted their trans-Atlantic routes to Africa, where weak institutions are no match for transnational organized crime. Numerous press reports have named both Boko Haram and al Qaeda in the Maghreb as key players in the business of smuggling coke across the Mediterranean into Europe.

The State Department’s Bureau of International Narcotics and Law Enforcement noted in November that Colombia is once again the world’s largest exporter of cocaine. But Bolivia may be the more profitable place for cartels like FARC to operate.

That’s suggested by a January 2014 paper by David Spencer, a professor of counterterrorism at the William J. Perry Center at Fort McNair, and Hugo Achá Melgar, a Bolivian journalist who now lives in the U.S. It traces the rise to power of Bolivian President Evo Morales, a former union leader of the country’s coca-growers, or cocaleros.
