Editor's Note: This week's Security Weekly is a heavily abridged version of STRATFOR's annual report on Mexico's drug cartels. The full report, which includes far more detail and diagrams depicting the leadership of each cartel along with our updated cartel map, will be available to our members on Dec. 20. By Scott Stewart In our 2010 annual report on Mexico's drug cartels, we assess the most significant developments of the past year and provide an updated description of the dynamics among the country's powerful drug-trafficking organizations, along with an account of the government's effort to combat the cartels and a forecast of the battle in 2011. The annual cartel report is a product of the coverage STRATFOR maintains on a weekly basis through our Mexico Security Memo as well as other analyses we produce throughout the year.
