Until the Cartels get stupid and retaliate. Then Trump orders gloves off, fuck the Mexican governments wishes. It's only a matter of time now.
Agree with your sentiment, but disagree with the bolded part.
US military operating unilaterally in a partner nation is not going to work. That will very quickly put us into an Afghanistan 2.0 in our own backyard while (internationally) gaining us the goodwill of the Russians.
Any anti-cartel actions have to be hand in hand with Mexican support, similar to what we did with the Colombians.
