Air Superiority and Naval Capabilities are nullified by being good at hiding in buildings and sniping from roofs?
You remember where them cartels get their weapons and funding from?
Just cause a few commanders got trained by some Special Forces dudes don't mean they suddenly got the capabilities to counter the USA's military.
Besides the Mujahideen having Special Forces training, they had another thing that Cartels definitely don't have:
Fierce Religious Fervor
To be honest, if you really wanted to end all the cartels you could just literally buy them out. Send a billion a piece to each Cartel head and I bet they would peace it out.
You can't do that with religious radicals.
Also Special Forces training is highly overrated. They aren't giving them all the sauce. And the USA trains with all kinds of different countries.
