The government and the druglords, who rules Mexico?

Very good summary of the status of the joint US/Mexican war on druglords, which is mostly failing according to the authors.

Drug trafficking is Mexico’s cancer, bringing the population an indescribable number of problems, while it is barely being noticed back in the U.S. The issue is not simply the thousands of deaths in drug-related incidents every year, but also the government’s inability to control the drug cartels. This situation creates a profound sense of fatalism and disillusionment over the ability of elected officials and the security forces to effectively cope with crime and to honestly bring law and order to the community. Furthermore, rampant corruption and drug-related violence discourages foreign investment and prevents development, two issues that Mexico needs to resolve.
