“I think more and more Mexicans will respond in a similar fashion, as we ask ourselves why are Mexican troops up in the mountains of Sinaloa and Guerrero and Durango looking for marijuana, and why are we searching for tunnels, patrolling the borders, when once this product reaches Colorado it becomes legal,” said Jorge Castañe­da, a former foreign minister of Mexico and an advocate for ending what he calls an “absurd war.”

Peña Nieto has pledged to work closely with the U.S. government against powerful transnational crime organizations when he takes office next month. But he has stressed that his main goal is not to confront smugglers but to reduce the sensational violence and rampant crime — such as extortion, kidnapping and theft — that have soared in Mexico during Calderon’s six years in office.
