There's a war going on right now in Mexican border towns between the Mexican Government and the drug cartels.
It's my theory that this exercise is all about preparing in the event that that war spills over the border into the US.
My understanding that the military exercise is about fighting an insurgency. It would be real easy for the drug cartels to mix in with our Mexican American citizens and illegals.
Don't forget that Pancho Villa crossed over the border and attacked Columbus, New Mexico back in March of 1916.
