For several years now, STRATFOR has been closely monitoring the growing violence in Mexico and its links to the drug trade. In December, our cartel report assessed the situation in Mexico, and two weeks ago we looked closely at the networks that control the flow of drugs through Central America. This week, we turn our attention to the border to see the dynamics at work there and how U.S. gangs are involved in the action.

As part of STRATFOR's coverage of the security situation in Mexico, we have observed some significant developments in the drug trade in the Western Hemisphere over the past year. While the United States remains the top destination for South American-produced cocaine, and Mexico continues to serve as the primary transshipment route, the path between Mexico and South America is clearly changing.

These changes have been most pronounced in Central America, where Mexican drug-trafficking organizations have begun to rely increasingly on land-based smuggling routes as several countries in the region have stepped up monitoring and interdiction of airborne and maritime shipments transiting from South America to Mexico.
