President Barack Obama will be going to Mexico in April, the White House announced this week. And Homeland Security Secretary Janet Napolitano said the U.S. is sending more federal agents to the border, along with high-tech surveillance equipment.

Mexico’s drug cartels have infiltrated more than 200 U.S. cities. Napolitano told a Senate panel this week that “the cartels have fingertips that reach throughout the United States.” Lawmakers were told that the drug cartels now represent the most serious organized crime threat in the U.S.

Secretary of State Hillary Clinton visited Mexico this week, and she immediately made headlines when she publicly acknowledged the role that the U.S. plays in the drug wars currently gripping the Mexican people. The U.S., says Clinton, “can’t control our appetite” for drugs, and can’t stop the flow of automatic weapons purchased legally in the U.S. and illegally smuggled south and into the hands of drug cartels.

For weeks now, headlines have declared the emergency situation: thousands dead, and violence spilling across the U.S.-Mexico border.

Prof. Bruce Bagley

More than seven thousand people have lost their lives in drug-war-related deaths since January, 2007, according to research by the University of San Diego’s Trans-border Institute. Mexican President Felipe Calderon has sent some forty-five thousand troops and another five thousand federal police officers to confront the drug cartels across Mexico.

Bruce Bagley has long-studied Mexico and the dilemmas of Mexican democracy and the dynamics of US-Mexican relations. His research focuses on drug trafficking and security issues. Professor Bagley serves as the Chair of the Department of International Studies at the University of Miami. And he spoke with Maria about a week in which all eyes were on Mexico.

The Question of Legalization At this week’s Virtual Town Hall sponsored by the White House, President Obama addressed the issue of legalization—actually, he dismissed the question before it was asked.

Has your administration given any serious thought to how legalizing marijuana could help solve the economic crisis? We could tax this green product and create an influx of cash while reducing violence created by the war of drugs & illegal trafficking”
