Mexico definitely produces drugs of its own; in fact, a lot of meth production has moved to Mexico.
However, the massive flow of drugs and money through Mexico needs a lot more than Mexico could produce even if every acre were turned over to cultivation of the raw materials and every maquiladora began to produce the finished product.
Venezuela and Cuba are the big shipping points, and the money from the drugs goes back to the Marxist guerrilla groups and international terrorist groups such as ETA or Islamicist groups. There is actually a big investigation of this going on in Spain right now, although naturally, you won’t hear about it here since it makes Hugo look bad (well, even worse).
I think if we realistically regarded Mexico as being under attack, we’d be able to respond better. But that’s assuming that we would want to respond - which we wouldn’t, since we now have a government or at any rate a President that is on the side of Hugo and Fidel.
Yeah, I have to give my name and address to my local pharmacist just to make sure that the Mexican cartels' meth profits stay as high as possible.
