The only solution for Mexico?

Some time ago I suggested that the only resolution to Mexico's drug cartel reign of terror was a Mexican government deal with the cartels. Now that it has become obvious that the U.S. is both the cause and an exacerbation (American illegal drug purchases, Operation Fast and Furious, laundering $ for the cartels, etc. see prior posts) this solution seems even more inevitable. In this very pessimistic article this writer agrees.
"It will get worse here in Mexico, unless the Mexicans themselves do something about it. They probably cannot. Vicente Fox (former president of Mexico, as Americans are all aware) favors legalization everywhere, but the cartels can easily buy any country's politicians to prevent this. The Mexican public more and more favors reaching an accommodation with the narcos: “You sell your drugs and we will turn a blind eye, but put an end to kidnappings, extortion, and the murder of the uninvolved.” This might work because it would be in the interest of the traficantes, who could discourage kidnappers by killing them unpleasantly. Nothing that isn't in the interest of the nacros will work, since they are too strong to coerce".
