Undersecretary of the Army Joseph Westphal, the second-highest ranking civilian official in the U.S. Army, described the situation in Mexico created by drug prohibition as an insurgency and fretted over a scenario in which armed U.S. soldiers could be called to the border and/or into Mexico. Westphal is the most senior U.S. official to publicly compare Mexico’s drug cartels to an insurgency since Secretary of State Hillary Clinton made a similar assessment last September. Westfall — who said he was expressing a personal opinion, but one he had shared with the White House — said he didn’t want to ever see a situation in which "armed and fighting" American soldiers are sent to combat an insurgency "on our border, in violation of our Constitution, or to have to send them across the border."
