They are more powerful that ISIS was in 2013 before they got major cities and more powerful than the Taliban were during 2002-2019. And honestly, they may be more powerful than the Taliban are NOW as their country collapses around them. It's not like those extremists that were fighting for several years will not jump to their guns again and fight their former allies.
At the time, the Taliban are assumed to have about 75K-150K members. The Cartels have as many as 200K.

OK. Let's talk about the other minor counter-terrorism operations or involvements the USA is engaged in the past few years.
They have all taken place in countries hostile to the USA OR with the approval of the local government.
How did things in Syria go? Sure, ISIS is not there but ISIS never threatened the USA. The terrorist organizations that took over from ISIS (Al Qaeda) did.
Libya, where again there were militias doing the groundwork, is still in a state of chaos after 12 years. Much less oil is coming from Libya.
How did things in Yemen go? You know, the country that is in an Ukraine situation for the past 12 years and USA helps the aggressor?
Do you have large trade deals with Yemen's government recently?
Not to mention that while USA bombed in the early years of the war, the Saudis and militias were fighting on the ground. And still do.
Mali? Somalia? CAR? Sudan?
Did USA accomplished anything there? Not really. The money the militias were making there to buy USA guns were made by illegal means, including drugs. Or trafficking immigrants to Europe.
That is what I am trying to say: Those special operations that the USA was bomb-and-go didn't do much except when they were punitive operations.
Yes, the USA can do an operation and take out hundreds of Cartel fighters for every USA citizen killed, to drive home the message that you don't mess with Americans. That will not stop THE DRUGS, that will help reduce the danger to American tourists in Mexico.
Because you say that Graham's Special operation idea is viable and a good idea. It is not. Just bombing a few sites would accomplish nothing as far as drug consumption in USA goes. Perhaps it will even make things worse as Mexico will cooperate even less.
If you want the USA to punish the Cartels for killing Americans, by all means, this could work. Napalm a few of their fields, with the goons inside. Kidnap some local druglords mid-ranking fish and ignore Mexico when it angrily foams at the mouth about how-dare-you.
But it won't stop the drug flow.
