On Thursday, U.S. President Barack Obama arrived in Mexico City to meet with his counterpart, Mexican President Felipe Calderon.  The issue of drug violence quickly took center stage, with the president again promising that the U.S. will do all it can to help Mexico win its war with the drug cartels.
