I definitely believe you. I stayed REALLY far away from anything near Michoacan or Guerrero because those areas are still in dispute. You can basically draw a few lines in Mexico, and you'll see a direct relationship between the frontiers of cartel territory and fighting. Juarez, Durango, Monterrey, Chihuahua, are all cities that are smack in the middle of these lines (some a little to the left, a little to the right, but it's a general rule) and they've all seen their share of violence in the last 5 years. This isn't a coincidence. It's all related to the ways cartels fight. I think the US won't be able to even discuss the issue until more Americans actually understand the complexities (both geographic and political) of Mexico itself.
I hate to say it, but regardless of who is in power (Democrats or Republicans) we simply won't see any kind of smart policy because we're addressing it they same way that we addressed the gang problem in the 80s. We keep pretending that these guys are basically gangs running around and moving drugs. However, the reality is that they're more or less institutions within their areas of control. A lot of people get fed because of these cartels. At the street level and at the political level. I was in Queretaro a few weeks ago and had a chat with someone who works within some agency that deals with public works. She was telling me that the PRI's candidate had been entirely financed by the Gulf Cartel.
How the hell does the Obama administration even begin to talk about Mexico's drug issue when there are governors/representatives/municipal presidents in the country financed by cartels? How would a Republican, whose policies range from the myopic suggestion of closing the border to charging 100K for illegal immigrants (depending on the candidate of course) deal with that? They won't. They'll all keep suggesting silly things that won't even begin to fix the issue in any depth.
I'm not suggesting working with cartels. However there is no way any American administration, regardless of who is in power can discuss Mexico to any degree when they can't even imagine what it's like to live in the country. That's for damn sure.
