I'd definitely support military action against the cartels - with overwhelming force. Armor, artillery, light weapons infantry, ground support aircraft, whatever it takes to send the unmistakable message that we will defend our borders.
Beforehand, however, I'd send a message to the U.N. to butt the **** out of our little adventure. Resolutions, demands, requests, political pressure, all of that emanating from the U.N. is meaningless. We're going to do what we have to do.
