Michoacana in order to defeat the Zetas.
For those of you not aware, the Zetas were birthed from a previous US war on drugs effort in the 90s when US military personnel trained Mexican special forces on counter-insurgency and drug warrior tactics (does this sound familiar?). These newly-trained, US-approved drug warriors then switched sides, offering their services to the Gulf cartel as bodyguards, enforcers, and assassins. Now, a decade later the Zetas have become powerful in their own right and have branched out to create their own bonafide cartel, an organization that has seen WalMart-like expansion in the last few years such that the other cartels are now threatened. So much so, that they have even displayed banners telling President Calderón to remove the army so that they can eliminate the Zetas. I guess they regard the military as more of a nuisance rather than a threat to their operations.
And the killing still continue, regardless of the intense rhetoric on both sides of the border, with 31 added to the yearly total now at 2,898.
