At tonight’s presidential debate on foreign policy, we can expect questions related to the civil war in Syria, the U.S.-led war in Afghanistan, and the broader war on terrorism, including the September 11 Benghazi attack. But I hope that debate moderator Bob Schieffer also asks President Obama and Governor Romney about another war—the one that is currently raging in Mexico and Central America.

This war isn’t between nations. There are no “insurgents,” and no ideologically motivated guerrillas trying to gain formal political power. Instead, it is a war driven by violent criminal organizations fighting to maintain or expand their control of illegal enterprises, most notably the drug trade.
