TL;DR: drug cartels are run like businesses. They are very rational. But, unlike your boss, their boss can also shoot you in the face if you annoy them too much

It's the meth.
Much as I despise them, I'm not so sure that would be the case. I seem to remember folks saying the same about the Taliban, and the cartels have a lot more money and high-tech kit, than the Taliban.
Asymmetric warfare is a tough gig, on all sides.
* A conventional military war, on a battlefield: Neither Saddam Hussein's military nor the cartels nor the Taliban would last long against the US.
* An unconventional insurgency: The Iraqis quickly turned to this approach and it worked very well for them, as it did for the Taliban. The Taliban won, and the Iraqi insurgency almost drove the US out of Iraq and was eventually co-opted.
The cartels of course would choose the latter. They, the Taliban, etc. are not suicidal.
The US decided to leave because staying was not politically popular, and left. They were not beaten by the Taliban, they were beaten by the political climate at home.
If someone is actively kicking your ass, then they decide that you aren't worth the effort to keep hurting and decide to walk away, that doesn't mean you "won" the fight even if you get what you want afterwards.
It's also a perfectly common, expected way to win a war: First, wars always end with political solutions. The most well known principle of warfare is that it is 'politics conducted by other means' (i.e., by violence rather than by law or diplomacy). If there is no political solution, the war never ends. That's why the US didn't win the war in Afghanistan after decades - they couldn't create a stable political solution because they were unable to impose one on the Taliban, who in the end imposed one on the US and its allies.
Victory by outlasting enemy resources, including political will, is fundamental to warfare; wars end when resources to fight (for the political outcome) run out, but few end in total kinetic destruction of those resources - someone runs out of money or political will. It's also the explicit strategy of insurgencies. Enemies of the US know it very well and have used it for generations - that is how North Vietnam won, for example. When the Soviets invaded Afghanistan, the Afghans famously told them, 'you have the clocks (the technology), we have the time'.
Your parents get frustrated and leave. You now take a cookie from the jar.
You have a cookie, but that doesn't mean you won the argument.
I mean, some sort of cartels would bounce back after any "war on drugs" because supply and demand, but the people running them aren't hankering for martyrdom or glory over consolidating their territory and accumulating.
There isn't a real analogy there because cartel leaders have no official state support anywhere, let alone in a bordering nuclear power, but even if they did, it hardly seems reassuring from their perspective to know the drug trade will outlive them after they all get killed. It's different when you're deeply religious and believe what you're doing is worth dying for and the larger arc of history is more important than your own life and wellbeing. I don't think drug lords think that way.
I didn’t mean to start this giant thread about Mexican Cartels but here we are. Most think it’s just an isolated problem. Others know it’s more widespread. I simply stated that these murderous thugs are out there in full force with technology and armored vehicles. If provoked, they would lash out. It’s ridiculous because of course going up against the US is a losing proposition but each “generation” of cartel leader thinks they can somehow manage it.
In any case that was a war against a hardened, experienced, determined enemy fighting for its freedom from any form of colonial occupation, both as a formal military and as an insurgent force in South Vietnam.
I scarcely think the Mexican population would rise up in defense of the cartels here.
The Battle of Culiacán, also known locally as the Culiacanazo and Black
Thursday, was a failed attempt to capture Ovidio Guzmán López, son of Sinaloa
Cartel kingpin Joaquín "El Chapo" Guzmán, who was wanted in the United States
for drug trafficking.
Around 700 cartel gunmen began to attack civilian, government and military
targets around the city, despite orders from Ovidio sent at security forces'
request. Massive towers of smoke could be seen rising from burning cars and
vehicles. The cartels were well-equipped, with improvised armored vehicles,
bulletproof vests, .50 caliber (12.7 mm) rifles, rocket launchers, grenade
launchers and heavy machine guns.
