A new Pentagon task force is racing to map the full scope of cartel networks that have spent nearly two decades forging operational ties with Iranian-backed militants — connections under renewed scrutiny as Iran’s proxy militias rejoin the fight following devastating American-Israeli strikes on Tehran.
The February 22 killing of the leader of the Jalisco New Generation Cartel, Nemesio Oseguera Cervantes, in a Mexican military operation assisted by American intelligence represents the first major success for the new Joint Interagency Task Force Counter-Cartel, launched a mere 38 days earlier at Fort Huachuca in southern Arizona.
The raid that ended El Mencho’s reign exposed a complex threat that officials say has been maturing for years. The new counter-cartel effort, known as the Joint Interagency Task Force Counter-Cartel, brings together analysts from the FBI, CIA, National Security Agency, Drug Enforcement Administration, and Immigration and Customs Enforcement under military intelligence officer and Air Force Brigadier General Maurizio Calabrese.
The task force’s mission is to identify, disrupt, and dismantle cartel operations threatening the United States. That includes heading off joint operations between Mexican drug cartels and Mideast terror groups like Hezbollah.
Intelligence assessments warn that Hezbollah has conducted explosives training for Mexican drug cartel members since at least 2010, though the relationship dates back at least as early as 2008. That’s when El Universal first reported that Sinaloa cartel members traveled to Iran via Venezuela for weapons training. The reporting indicated extremist group members were marrying Mexican and Venezuelan citizens to adopt Latino surnames for easier entry into the United States.
The financial scale of the arrangement became clearer in 2011 when the Justice Department indicted a Colombian-Lebanese drug trafficker, Ayman Joumaa, for laundering more than $850 million in Los Zetas cartel earnings through fronts including the Lebanese Canadian Bank. Prosecutors on the case alleged the money was remitted to Hezbollah.
“The relationship between the cartels and Hezbollah is long-standing, significant and multifaceted,” the senior director of the Counter Extremism Project, Hans-Jakob Schindler, told The New York Sun. Mr. Schindler said the “strategically most significant part” of the relationship between the cartels and Hezbollah is financial cooperation in the international illicit drug trade.
“This also includes money laundering activities that Hezbollah is now also able to offer other organized crime networks as a service,” he said, adding, “This role has only increased since the war with Israel following the attack of Hezbollah on Israel” the day after Hamas’s assault on October 7, 2023.
Mapping the Networks
General Calabrese compared his team’s mission to targeted killing campaigns previously waged against terrorist organizations like Al Qaeda and the Islamic State, though the modus operandi are unique.
“The cartels operate differently than al Qaeda or ISIS, different motivations, which makes it even more important for us to identify entire networks so that we can disrupt and dismantle them,” the general said.
General Calabrese estimates that hundreds of leaders occupy the upper echelons of Mexican organized crime, supported by as many as a quarter-million lower-level operatives.
A Latin America security studies professor at the U.S. Army War College’s Strategic Studies Institute, Evan Ellis, told The New York Sun that while not revolutionary, “bringing together the right people in the military, intelligence, and law enforcement” focused on cartel arrangements is a useful step.
JIATF Counter-Cartel reportedly played a role in providing key information to Mexican Armed Forces in the killing of El Mencho. But while connections exist between cartels and groups like Hezbollah, their significance may be overstated.
“My sense is that Hezbollah is not the most significant partner of the cartels,” Mr. Ellis said. “The relationship is more occasional and opportunistic, for example, in areas such as money laundering, and possibly some limited interactions involving arms sales and training.”
The Iran Connection
Some of the most visible evidence of cartel-Hezbollah connections has emerged from an unexpected source: American prisons. U.S. law enforcement officials noted in 2008 an increased number of tattoos on prison inmates, particularly in the Southwest, bearing words written in Farsi and and expressing Hezbollah loyalty and imagery.
In 2010, then-Congresswoman Sue Myrick wrote to Homeland Security expressing alarm. The Farsi tattoos almost always appeared with gang or cartel tattoos, linking Iran, Hezbollah, and the cartels.
Mr. Ellis said that is not definitive of an operational link. “The tattoos suggest that some network and personal connections exist — and possibly some fascination with Shia Islam, Qods Forces, or other elements among cartel members — but it is difficult to impute more,” he said. “The fact that Secretary of War Hegseth has an Arabic tattoo, for example, does not connect him to Al Qaeda.”
Beyond the tattoos, however, congressional testimony revealed additional indicators of an alliance, pointing to more concrete operational ties. For instance, a Mexican national with Lebanese family ties, Jameel Nasr, was arrested in Tijuana in 2010 attempting to establish a Hezbollah network. Recovered cartel explosives showed sophistication, suggesting a knowledge of Middle Eastern bomb-building techniques.
Collaboration also extends beyond training to infrastructure sharing. Sophisticated narco-tunnels resembling those used by Hezbollah in Lebanon have been found along the U.S.-Mexican border, suggesting knowledge transfer of specialized excavation techniques developed for paramilitary purposes.
“As far as the operational cooperation between international organized crime is concerned, of course, there has been cooperation as far as the purchase of arms and explosive materials by Hezbollah,” Mr. Schindler added.
Intelligence officials say Hezbollah helped Mexican cartels develop smuggling techniques and routes to bring drugs and operatives into America. Those same routes moving tons of fentanyl northward can transport operatives southbound or position them at staging areas throughout Mexico and Central America.
With El Mencho’s death potentially fragmenting one of Mexico’s most powerful and violent criminal organizations — known for its extensive drug trafficking, extortion, and smuggling networks across virtually every Mexican state — Hezbollah and other Iranian-backed groups may now exploit the cartel’s instability. Despite having had a limited footprint and revenue streams compared to other organizations, Hezbollah has a window to assert itself on the North American continent.
Security analysts anticipate that the Jalisco New Generation’s rivals in the many territorial conflicts playing out across Mexico may also seize on El Mencho’s death to test the organization’s resilience, either by pushing back against the cartel’s presence in their states or by consolidating their own power.
The Jalisco cartel “had a presence and was engaged in different criminal operations from drugs to oil theft to extortion in virtually every Mexican state,” Mr. Ellis said. “The killing of El Mencho will likely unleash a wave of violence beyond the initial ‘wave of protest’ by the cartel after his death.”
The Iran Factor
Scrutiny of cartel-terror connections intensified dramatically following the February 28 American-Israeli operation that killed Iranian Supreme Leader Ali Khamenei and triggered sweeping Iranian retaliation across the Middle East. Iranian-backed militias in Iraq, including Kataib Hezbollah and Harakat Hezbollah al-Nujaba, launched drone and rocket attacks against U.S. forces.
A Tehran-backed militia coalition, the Islamic Resistance in Iraq, claimed 16 attacks using dozens of drones on February 28 alone, with additional strikes targeting American bases near Erbil. After more than a year of restraint following the ceasefire, Lebanese Hezbollah rejoined the fight with rocket attacks into Israel, marking the first such assault since November 2024.
Iran’s Islamic Revolutionary Guard Corps is also attempting to disrupt travel in the Strait of Hormuz, through which roughly 20 percent of global oil exports flow, with one attack already setting ablaze a U.S.-linked oil tanker. The U.S. military destroyed multiple Iranian naval vessels and struck Iranian proxy positions in Iraq to degrade Tehran’s power projection.
While Iranian-backed groups killed at least 603 U.S. troops in Iraq between 2003 and 2011, and its proxies conducted more than 180 attacks against American forces in the Middle East between October 2023 and November 2024, wounding more than 180 service members and killing three, Iran’s Revolutionary Guard Corps has remained arms-length from the action.
“IRGC operatives simply paid individuals from organized crime networks to conduct such attacks independently, without further operational or logistical support by the IRGC,” Mr. Schindler explained. “Especially in Europe there have been several cases in which the IRGC simply purchased attacks against individuals,” whether Iranian opposition or Israeli and Jewish targets, he said.
The Response in the Homeland
In 2025 alone, U.S. officials prevented more than 10,000 individuals with narco-terrorism ties from entering the country and placed more than 85,000 others on the terror watchlist, according to the Office of the Director of National Intelligence. Additional intelligence led to visa revocations, arrests, deportations, and other investigations.
The dramatic expansion of the National Counterterrorism Center’s watchlist reflects growing awareness within intelligence agencies that the convergence of drug trafficking and terrorism has created a hybrid threat that traditional law enforcement approaches cannot address alone.
The 2025 designation of cartels as foreign terrorist organizations represents a fundamental shift in how the U.S. government views and responds to transnational criminal organizations operating along its southern border. As the task force maps cartel networks following El Mencho’s death, investigators are racing to determine what operational capabilities may have been prepositioned on American soil by Hezbollah, other Iranian-backed groups, and their Mexico-based sponsors.
“The answers to those questions will determine whether the narco-terror alliance is primarily a financial arrangement or has evolved into something far more dangerous,” Mr. Ellis said.
Given the current situation with Iran, its targeting of civilian infrastructures in neighboring countries, and its history of using proxy warfare, Mr. Schindler said it is possible that the Iranian regime could once again task Hezbollah to conduct a terror campaign.
“If this is the case, it is likely that Hezbollah would use its cartel contacts to further its ability to do so, including potentially inside the United States,” he said.
