'Will the American government scream bloody murder if Mexico tries to do that...yup, probably. Will the cartel's murder anyone who even attempts to take away their major source of power...yup, probably.
Hey, it won't be easy. But something has to be done.'
So obviously I am aware of all that.
But it has to be done.
Surround the government buildings AND protect the politician's families with the military - while the politician's pass the legalization. And don't make a big discussion about it...do it all behind closed doors, make sure they have the votes and then pass the law. Done.
What's your solution? Let the cartels run their regions, anyway they want, murdering anyone they want, forever?
