A Colombian rear admiral who served along the country's Caribbean coast was removed from his post Monday for alleged links to drug traffickers. Rear Admiral Gabriel Arango is only the latest in a series of military officers investigated in what has become a widening probe of connections between the military and the country's powerful drug trafficking organizations.

too much trouble over this plant -- just legalize it already

Arango protested his innocence, pointing to his record in seizing drugs as a naval commander. "Never in my life have I been linked to any drug traffickers," he told Caracol Radio.

It's not just the navy. Colombian prosecutors are currently investigating at least eight army officers for alleged collaboration with the Norte del Valle cartel, the country's most violent drug trafficking organization.

The Colombian military has been the recipient of billions of dollars in US counter-narcotics and counter-insurgency aid under Plan Colombia. But coca and cocaine production have remained relatively steady despite the billions.

That's because there are too many vested interests benefiting from the drug trade and the drug war in Colombia, a now-imprisoned former paramilitary commander told Reuters this week. Salvatore Mancuso, former leader of the murderous Northern Bloc paramilitary drug trafficking organization who surrendered in a sweetheart deal in 2004, said those vested interests include politicians and military officers who collude with drug smugglers, contractors connected to a multibillion-dollar US anti-narcotics program, and companies that sell chemicals used to process cocaine.

"As long as there is a conflict in Colombia, all this will flourish," Mancuso predicted. "We have to cut off the guerrillas' oxygen supply, and that oxygen supply is cocaine."

Mancuso, whose sweetheart sentence is now threatened by a Colombian Supreme Court ruling demanding harsher treatment of those who killed innocents in their fight with leftist guerrillas, is not a disinterested observer. He is now offering his anti-cocaine strategy and services to the US government, undoubtedly in hopes of getting a US indictment for drug trafficking dropped.

Mancuso's prescriptions sound familiar, too. "First we need all-out coca eradication. Second a coherent plan for security and a state presence in these rural areas," Mancuso said. "Then there has to be social and economic development for each community."

Meanwhile, drug prohibition and Colombia's drug war drag on, and those in a position to profit are doing so.
