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. The cables, from the cache obtained by WikiLeaks [offer glimpses of drug agents] 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. 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. The D.E.A. now has 87 offices in 63 countries and close partnerships with governments that keep the [CIA] at arm's length. Created in 1973, the D.E.A. has steadily built its international turf. Since the 2001 terrorist attacks, the agency's leaders have cited what they describe as an expanding nexus between drugs and terrorism in further building its overseas presence.
