William R. Brownfield: “Implementation of an effective counternarcotics plan for Colombia is more important now than ever.”

The overwhelming majority of the heroin that is now entering the United States is coming from Mexico.

If we do not have an adequate and functioning road system, counter-narcotic strategy will not succeed.

To solve the problem, we must cut off international supply.

I do believe that the federal Government of Mexico today has far better, more professional, better trained and equipped institutions than they did at the start of the Merida Initiative 7 or 8 years ago.
