WASHINGTON — The Drug Enforcement Administration has been transformed into a global intelligence organization with a reach that extends far beyond narcotics, and an eavesdropping operation so expansive it has to fend off foreign politicians who want to use it against their political enemies, according to secret diplomatic cables.

 

In far greater detail than previously seen, the cables, from the cache obtained by WikiLeaks and made available to some news organizations, offer glimpses of drug agents balancing diplomacy and law enforcement in places where it can be hard to tell the politicians from the traffickers, and where drug rings are themselves mini-states whose wealth and violence permit them to run roughshod over struggling governments.

Diplomats recorded unforgettable vignettes from the largely unseen war on drugs:

¶In Panama, an urgent BlackBerry message from the president to the American ambassador demanded that the D.E.A. go after his political enemies: “I need help with tapping phones.”

¶In Sierra Leone, a major cocaine-trafficking prosecution was almost upended by the attorney general’s attempt to solicit $2.5 million in bribes.

¶In Guinea, the country’s biggest narcotics kingpin turned out to be the president’s son, and diplomats discovered that before the police destroyed a huge narcotics seizure, the drugs had been replaced by flour.

¶Leaders of Mexico’s beleaguered military issued private pleas for closer collaboration with the drug agency, confessing that they had little faith in their own country’s police forces.

¶Cables from Myanmar, the target of strict United States sanctions, describe the drug agency informants’ reporting both on how the military junta enriches itself with drug money and on the political activities of the junta’s opponents.

Officials of the D.E.A. and the State Department declined to discuss what they said was information that should never have been made public.
