What is the reason that we have not put boots on Mexico?
Would be about as difficult logistically as taking on Al Queda. This isn't a uniformed army that you can just have battles with. They would be in hiding and real intilligence work would have to be undertaken and you can't just carpetbomb them since they live within the community. We can do it if needed but since a threat to us isn't imminent there isn't a reason to put such a max effort to stomp them out. They also know we are their customers so they wouldn't dare deliberately start screwing around with Americans on American soil.
This. Plus, the way it is, it's financially beneficial to both parties. Drugs have a huge impact on both economies in different ways. Also, the US would lose in the long run. Can't stop the dope, just not gonna happen.
Would lose how.
Would lode in the sense of not being able to completely eliminate drugs. I'm sure we would put a MAJOR dent in the game though, because we are a pretty powerful force. But I just envision something like cocaine being more rare. That wouldn't do anything but increase the demand and the selling price. As far as weed, most of it comes from Mexico, but we really don't need it. We can grow weed over here. Domestic production would just increase.
