I wrote one of my master papers on Mexico being the greatest threat to our national security. Those numbers posted are low. I will have to dig out my paper to see what was reported last year when I wrote the paper.

Another thing is that there is evidence that the drug cartels are trading drugs/money for training in both bomb making and insurgent techniques. There was a spike in the amount of attacks as well as the sophistication of the attacks.

I agree with you Ronin, the border is too relaxed and offers too much of a target for our enemies as the war in Afghanistan begins to wind down.
