Interdiction rarely works. If Guinea-Bissau were to remove illicit drug operations from within its territories then the cartels would move elsewhere. Known as the hydra effect, once one potential drug route is cut off then another one is found and the trade continues1. This was the case for interdiction efforts between the US and Mexico. Initial government operations were successful at interdicting drugs being shipped between South American and Florida. In retaliation, traffickers began to use the US-Mexico border. The border witnesses large volumes of trade and interdicting the drugs proved to be nearly impossible2. It is logical to conclude that traffickers would find a new way to ensure drugs reached the Western markets if Guinea-Bissau sought US assistance.  1) Boaz,D. ‘The Hydra-Headed Drug Business’, CATO institute, 30 June 1998  2) Morton,D. ‘The War on Drugs in Mexico: a failed state?’, Third World Quarterly,39:3, pg.1639
