Drones with Hellfires would be more efficient
They are working on that.
A few hellfire strikes on cartel activity on the Mexico side of the boarder would be an effective deterent as well. I'm all for that.
Then we would get into Illegals wanting to announce, "I'm just an illegal immigrant, not a drug smuggler, don't shoot."
Hellfires on ANYTHING would be great. Can I run the boat?
