U.S. Agent's Killing Hints at Drug Prohibition War Tensions

Jaime Zapata's killing marks the first murder of an American agent in the line of duty in Mexico's drug prohibition war, which has raged relentlessly since President Felipe Calderón took office in December 2006. As such, it adds extra pressure to the already strained U.S.-Mexico drug prohibition alliance. Publicly, the Calderón and Obama administrations have continued to paint a rosy picture of the U.S. and Mexico marching side by side to defeat the common adversary of drug trafficking organizations. But as revealed in WikiLeaks cables and offhand comments by officials on both sides of the border, tensions are growing. U.S. officials complain that they cannot rely on Mexico's institutions — and this concern is exacerbated when their lives are on the line.
