Mexican Drug Trafficking Organizations Draw Guatemalan Army to Jungles Where It Fought Civil War

The once-fearsome Guatemalan army has returned to the jungles where it battled Marxist guerrillas a generation ago, this time to hunt shadowy Mexican drug traffickers fighting for control of strategic smuggling routes to the United States. The military operations are the clearest sign yet that as Mexico's wealthy drug trafficking organizations spread into Central America, wary but weak governments here are preparing to follow Mexican President Felipe Calderon's U.S.-backed decision to turn the armed forces against the traffickers. That prohibitionist strategy has failed to slow the violence in Mexico, which has left more than 34,000 dead in four years.
