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.

Some U.S. officials fear the coming of an unofficial truce with cartel leaders. The Mexicans see it otherwise. “The objective of fighting organized crime is not in conflict with achieving peace,” said Eduardo Medina Mora, Mexico’s ambassador to the United States.
