Since [the days of Al Capone,] Chicago officials have awarded Public Enemy No 1" status to only one other person: cartel billionaire Joaqun Guzmn Loera, better known now to the world over as "El Chapo". But nearly seven weeks before [his February] capture at a beach resort, the Mexican newspaper El Universal reported how US agencies had armed and financed El Chapo's Sinaloa criminal empire for at least 12 years. That link has been substantiated by DEA and Justice Department court testimonies, and even US agents confirmed the financing had been approved by high-ranking officials and federal prosecutors. But the American media barely reported how entrenched the American government has become in the Mexican drug trade. The latest installment of the "war on drugs" has killed 100,000 people since its official declaration by Mexican President Filipe Calderon and US President George W Bush in 2006. During this period, the US-El Chapo partnership was reportedly never closer: under the deal, Washington allowed El Chapo's Sinaloa cartel to carry on business as usual while top Sinaola members, for their part, provided information on their rivals. DEA agents met with their informants more than 50 times, El Universal reported, as the agents offered their whisperers immunity. American patronage goes well beyond stoking the largest and most powerful of the Mexican cartels (Sinaloa), as well as the most heinous (Golfo and Los Zetas). Drug arrests of cartel associates amounted to less than 2% of over 50,000 arrests made in the first four years of the Bush-Calderon partnership.
