Gulf Cartel goes public on break-up with former allies Los Zetas - Monsters and Critics
Many discussion about illicit developments assert that various groups, e.g. FARC and al Qaeda, are "linked," in some coordinated, directed, coherent movement.
However, as the above article detailing the breakup of the Gulf Cartel and the Zetas illustrates, illicit groups can have divergent goals and purposes, that they can delink, diverge, and even fight one another.
So the next time that you hear that, say, the 'Ndrangheta may be doing business with the Burmese, take the report with a grain of salt and recognize that this probably does not mean that they are therefore subsidiaries of some larger Moriarity/Fu Manchu type conspiracy.
