For the past seven years, Mexico and the United States have put aside their tension-filled history on security matters to forge an unparalleled alliance against Mexico’s drug cartels, one based on sharing sensitive intelligence, U.S. training and joint operational planning. But now, much of that hard-earned cooperation may be in jeopardy.
The December inauguration of President Enrique Peña Nieto brought the nationalistic Institutional Revolutionary Party (PRI) back to power after 13 years, and with it a whiff of resentment over the deep U.S. involvement in Mexico’s fight against narco-traffickers. The new administration has shifted priorities away from the U.S.-backed strategy of arresting kingpins, which sparked an unprecedented level of violence among the cartels, and toward an emphasis on prevention and keeping Mexico’s streets safe and calm, Mexican authorities said.

President Felipe Calderón said that his police and soldiers are dangerously outgunned because U.S. authorities are failing to stop the smuggling of high-powered weapons into Mexico. His attorney general called for more aggressive prosecutions of gun smugglers, saying that the U.S. constitutional right to bear arms doesn’t protect them.
