the only country that i know of that has dealt with organized crime successfully is indonesia and at lesser extent to salvador, both countries run a zero tolerance policies, in the case of indonesia they actually run a minus zero policy, you get hanged by the neck until death of you're caught with a gram of shit there but neither of this countries are a major corridor for drugs.  mexico is much more complicated a direct war against the cartels always end up with major blood spill all over and if america tries to get mixed up in this shit it'll spill over the us. people think it'll be just going over to mexico and kicking shit up until you start seeing politicians family members getting kidnapped and marshalls being killed.
