I would say yes, but it's not that simple. If u designate drug cartels as terrorist then the army would be able to be deployed and get involved. So this could open the door for central and South American us army being deployed into those soverign countries for the sake of counter terrorism missions. I say no because drug cartels are already being handled by local police, that state they are in and other law enforcement. Changing a label is a big deal when it could me US Army invades Mexico because it's overrun with cartels. Also as a veteran who went through the shit show Iraq shit it never ends well for our troops when we invade independent nation's. I have to say no because of the potential gravity of this simple label change could have.
