Now the smugglers have subs:
A submarine-like vessel filled with hundreds of millions of dollars worth of cocaine was seized off the Guatemalan coast, U.S. officials said....Several drug-carrying submarines operated by Colombian drug cartels have been discovered in recent years. [emphasis mine]
There's nothing like basic economics to undermine the drug war. If you buy it, they will come. In subs, if necessary.
