The Mexican military's killing of CJNG leader "El Mencho" Oseguera Cervantes on February 22 is still the dominant story in the hemisphere — CJNG retaliation violence spread across 20 states, the U.S. Embassy issued a shelter-in-place alert, and the cartel's succession fight is just beginning. Simultaneously, Trump's "Shield of the Americas" summit produced a 17-nation anti-cartel coalition with real military teeth — Ecuador is already conducting joint lethal operations with U.S. forces — but the exclusion of Mexico, Brazil, Colombia, and Uruguay is creating a visible geopolitical fault line in hemispheric security. Both stories are connected: El Mencho's death created the political opening for Trump's Miami summit, and the summit's outcomes will shape how the post-Mencho CJNG is ultimately confronted.
The U.S. Embassy in Mexico issued an emergency shelter-in-place alert Sunday, warning American citizens to stay indoors as CJNG retaliation violence spread across multiple states. The alert came roughly two weeks after the February 22 military killing of CJNG founder Nemesio 'El Mencho' Oseguera Cervantes — the cartel's coordinated response included approximately 250 roadblocks built from hijacked cargo trucks, buses, and private vehicles set ablaze across highways and urban roads in Jalisco, Michoacán, Guanajuato, Colima, Tamaulipas, Zacatecas, Aguascalientes, and Sinaloa.
Security Secretary Omar García Harfuch revealed in an interview Sunday that the final operation against El Mencho was planned in just 24 hours, despite years of intelligence groundwork. The breakthrough came when CNI and military intelligence penetrated the cartel leader's inner security circle through a source connected to one of his romantic partners, per El País.
Mexican security forces conducted a separate operation in Guerrero over the weekend, dismantling a clandestine lab and seizing approximately 300 kg of methamphetamine, 24,000 liters of liquid chemical precursors, and 20,000 kg of solid chemical substances — estimated damage to cartel operations of roughly 309 million pesos (~$15M USD), per the Cabinet of Security.
Mexico was excluded from Trump's Shield of the Americas summit — not invited, alongside Brazil and Colombia. President Sheinbaum cited Mexico's non-intervention policy and publicly rejected any suggestion of U.S. military strikes on Mexican territory, though Mexican and U.S. officials acknowledged that American intelligence support contributed to the El Mencho operation.
International investigators have published findings on an illegal mercury trafficking route running from the port of Manzanillo, Colima — a CJNG stronghold — through Peru's Port of Callao and into Bolivia, with the operation dating to June 2025. The route implicates CJNG in supply chains for illegal gold mining across the Andean region.
President Trump hosted the 'Shield of the Americas' security summit Saturday at his Doral, Florida golf club, gathering leaders from Argentina, Bolivia, Chile, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guyana, Honduras, Panama, Paraguay, and Trinidad and Tobago, plus Chile's president-elect José Antonio Kast. The summit produced a formal charter affirming democratic principles, private enterprise, and the right of nations to act against transnational criminal organizations.
Trump proposed using U.S. missile strikes against cartel targets in Latin America, framing it as part of a 'Trump Corollary' to the Monroe Doctrine. He called Mexico the 'epicenter of cartel violence' in the hemisphere and warned the U.S. would act unilaterally if necessary, though he offered no legal framework or rules of engagement for how such strikes would work.
Secretary of Defense Pete Hegseth told the assembled leaders that Washington is ready to conduct solo military operations against cartels in Latin America and called on regional governments to fight 'narcoterrorists.' Secretary of State Marco Rubio conducted separate bilateral meetings with right-leaning leaders on the sidelines, focused on building operational — not just rhetorical — security structures.
The coalition charter includes provisions for joint military operations, intelligence sharing, and coordinated border enforcement. Seventeen nations signed. Mexico, Brazil, Colombia, and Uruguay were absent — a split that reflects the ideological sorting happening across the hemisphere right now.
U.S. and Ecuadorian forces conducted a joint lethal strike Friday on a Comandos de la Frontera camp in the Sucumbíos region of the Amazon, destroying a facility used by alias 'Mono Tole' as a rest and training site with capacity for approximately 50 combatants. Video of the explosion was released publicly by both the U.S. military and President Noboa, per CNN en Español.
Separately, Ecuadorian naval forces sank a narco-submarine near the country's northern border last week as part of the ongoing joint campaign with U.S. forces, CBS News reported. The U.S. military also confirmed a strike on an alleged drug vessel in the Eastern Pacific that killed six people, though it is unclear if that operation was Ecuador-linked or a separate Pacific interdiction.
President Noboa was among the most vocal supporters at the Shield of the Americas summit, declaring that 'the time is up' for criminal groups who treated the Americas as their territory. Ecuador's partnership with the U.S. has deepened substantially — the joint operations in Sucumbíos represent the most visible kinetic cooperation between Washington and a South American government in recent memory.
The ELN released five Colombian National Police officers it had been holding hostage, Notimérica reported Monday. The gesture comes ahead of Colombia's March legislative elections, but security analysts at Portafolio warn that at least 14 municipalities — particularly in Antioquia's northeast — face high electoral risk due to active operations by the Clan del Golfo, ELN, and FARC dissidents.
In Vegachí, Antioquia, five bodies were found shot to death in the rural area of Corinto — a massacre in a zone already flagged by the MOE (Misión de Observación Electoral) as high-risk for election-related violence. Days earlier, on March 5, military units from the Fourth Brigade dismantled a Clan del Golfo communications center in Sonsón, also in Antioquia.
Colombia was excluded from Trump's Shield of the Americas coalition and was not invited to the Miami summit. President Petro has publicly called on Trump to halt the U.S.-Iran conflict. The ideological distance between Bogotá and Washington continues to widen at precisely the moment regional security cooperation is becoming most structured.
Colombia's Defense Ministry denounced the illegal crossing of approximately 2,400 people from Venezuela through irregular border paths to participate in Sunday's Colombian legislative primaries, calling it a crime in flagrante and opening an investigation.
Bolivia made a clean geopolitical break at the Shield of the Americas summit, with President Rodrigo Paz signing the coalition charter and aligning Sucre firmly with Washington's security agenda. Paz — a right-leaning centrist who took office in November — has already eliminated U.S. visa requirements, announced the return of a U.S. ambassador, and secured multi-billion dollar loans from the Inter-American Development Bank, per the New York Times.
Bolivia's president also met with El Salvador's Bukele on the sidelines of the summit, describing the Bukele model of prison control as a reference point for Bolivia's own anti-crime strategy. Bolivia's pivot away from its historically anti-U.S. posture is one of the more significant diplomatic shifts in South America in recent years.
The Trump administration is moving toward allowing limited Venezuelan oil sales to Cuba's private sector, with Treasury granting a carve-out for private-sector transactions. Trump himself has framed Venezuelan oil access as a national security and affordability issue for American consumers, Fox News reported.
The broader Venezuela situation involves the post-Maduro political transition following his capture by U.S. forces — an event that is now being cited openly by U.S. officials as a precedent for the hemisphere's new security posture. Approximately 2,400 Venezuelans illegally crossed into Colombia via irregular paths to vote in Sunday's primary, raising concern in Bogotá about border enforcement.
Trump signaled at the Shield of the Americas summit that he will 'take care of Cuba,' though analysts note the administration is currently betting on internal economic pressure and elite fragmentation rather than direct military action. A parallel diplomatic track is reportedly underway — Foreign Policy and other outlets report that informal discussions about Cuba's nickel and cobalt reserves are being explored as a potential basis for sanctions relief in exchange for political transition.
President Díaz-Canel called the Shield of the Americas summit 'reactionary and neocolonial,' denouncing U.S. military pressure across the hemisphere. Cuba's isolation within the new regional alignment is near-total — the island is not part of the coalition, faces continued U.S. pressure, and is watching its Venezuelan energy lifeline grow more uncertain.
Investigative reporting published Sunday traced an illegal mercury trafficking route from Manzanillo, Colima (Mexico) to Peru's Port of Callao, with final destination in Bolivia. A container departing June 1, 2025, listed 800 sacks of crushed stone totaling 20 metric tons as cover cargo. The route connects CJNG directly to illegal gold mining supply chains in the Andes — a cross-border criminal economy that the El Mencho killing does not automatically disrupt.
Peru's upcoming 2026-2031 elections have prompted scrutiny of party platforms on illegal and informal mining — a Inforegión analysis found only 12 of 36 parties include concrete proposals on the issue, even as illegal mining remains one of the country's primary organized crime drivers.
Honduran President Nasry Asfura participated in the Shield of the Americas summit and highlighted agreements on regional security, foreign investment, fuel cooperation, and migration. Honduras signed the summit charter.
El Salvador's President Bukele met separately with U.S. Special Envoy for the Shield of the Americas Kristi Noem following the summit, per La Noticia SV, to discuss bilateral security collaboration under the new coalition framework. Bukele remains one of Washington's most prominent regional partners.
Panama and Costa Rica also signed the coalition charter. Panama's participation is notable given Washington's stated interest in preventing 'outside powers' from controlling the Canal — a concern U.S. officials have tied explicitly to China.
President Javier Milei traveled to Doral for the Shield of the Americas summit, where the Argentine government described the meeting as an opportunity to design joint strategies against organized crime and foreign interference. Milei and Trump's relationship appears to be consolidating — the two leaders have aligned on security, economic liberalization, and anti-China posture.
Argentina signed the summit charter. No significant domestic security incidents in the last 24 hours.
Brazil was not invited to the Shield of the Americas summit, and President Lula's government was publicly noted as absent. The exclusion reflects the ideological gap between Brasília and Washington — Lula has maintained warmer ties with Venezuela, China, and the Petro government in Colombia.
Australia's government updated its travel advisory for Brazil, maintaining a 'high degree of caution' recommendation citing crime, civil unrest, and security concerns — consistent with longstanding advisories around urban gang activity and police operations.
HIGH. Post-El Mencho CJNG retaliation violence remains active across 20 states, with the U.S. Embassy shelter-in-place alert still in effect as of Sunday. The operating environment for foreign nationals and commercial freight is severely disrupted in Jalisco, Michoacán, Guanajuato, Colima, and Tamaulipas. Watch for cartel succession dynamics within CJNG — that internal power struggle is the next major threat vector.
MODERATE. No significant security incidents in the last 24 hours. Guatemala signed the Shield of the Americas coalition charter. The MOE has flagged ongoing gang presence in border areas, but no acute developments today.
MODERATE. No significant developments. Belize is listed as part of the broader 17-nation coalition framework but was not prominently featured at the Doral summit. Baseline criminality in Belize City remains the primary concern.
ELEVATED. President Asfura returned from the Shield of the Americas summit with coalition commitments on security and investment. Domestic operating environment remains challenged by gang presence and corridor trafficking — watch how the coalition framework translates into on-the-ground enforcement capacity.
MODERATE. Bukele participated in the Miami summit and held follow-on meetings with Special Envoy Kristi Noem. His security model continues to draw regional interest, including from Bolivia. No new domestic security incidents reported in the last 24 hours.
MODERATE. Nicaragua was not part of the Shield of the Americas coalition. Ortega government's posture aligns more closely with Cuba and Venezuela. No acute security incidents in the last 24 hours, but the political environment restricts independent reporting.
MODERATE. Signed the Shield of the Americas charter. No significant security incidents. Costa Rica's participation in the coalition is notable given its traditionally non-militarized posture — watch whether domestic political debate emerges over the implications of the charter's joint military operations clause.
ELEVATED. Signed the coalition charter. U.S. officials have explicitly framed Panama Canal control as a strategic interest driving the Shield of the Americas initiative — that makes Panama's internal politics and Chinese infrastructure presence a live watch item under the new framework.
HIGH. Election-related violence risk is acute ahead of legislative elections, with 14 municipalities in Antioquia flagged as high-risk. The ELN hostage release is a tactical gesture, not a strategic shift. Bogotá's exclusion from the U.S. coalition creates a security cooperation gap at a bad time.
HIGH. Post-Maduro transition continues under U.S. pressure. The partial opening on oil sales to Cuba signals tactical U.S. flexibility, but the broader political situation remains unsettled. Irregular border crossings into Colombia demonstrate ongoing population movement and state control limitations.
HIGH. Joint U.S.-Ecuador lethal operations are now publicly confirmed and actively ongoing. The Comandos de la Frontera strike in Sucumbíos and the narco-sub sinking show an accelerating operational tempo. The interior of the country is seeing criminal violence spread beyond coastal hotspots — El País reported this trend as of March 3.
ELEVATED. Illegal mining remains the dominant organized crime driver, and only a fraction of parties running in upcoming elections have serious proposals to address it. The CJNG mercury trafficking route through Callao adds an international cartel dimension to Peru's domestic mining crime problem.
MODERATE. President Paz's pivot toward Washington is the headline — Bolivia signed the Shield of the Americas charter and is pursuing IDB financing and restored U.S. diplomatic relations. Domestic security environment is improving institutionally, but the country's role as a destination in the CJNG mercury route is a concern worth tracking.
ELEVATED. Excluded from the Shield of the Americas coalition. Lula's government faces a diplomatic isolation risk within the hemisphere's new security architecture. Domestically, police violence and gang activity in Rio de Janeiro remain at elevated levels per ongoing Amnesty International and Reuters reporting from late 2025.
MODERATE. Signed the Shield of the Americas charter. Paraguay is engaged in MERCOSUR's 2026 digitization and trade facilitation agenda. No significant security incidents in the last 24 hours, though the country's longstanding role as a contraband and money laundering corridor warrants baseline monitoring.
MODERATE. Notably absent from the Shield of the Americas summit — El País Uruguay reported Montevideo was not invited, reflecting the current government's more independent foreign policy posture. No acute security incidents.
MODERATE. Milei participated in the Miami summit and deepened the U.S.-Argentina alignment. No significant domestic security incidents. The government's anti-cartel posture is rhetorical for now — watch whether the coalition framework generates concrete operational commitments.
MODERATE. President-elect José Antonio Kast attended the Shield of the Americas summit even before taking office — a signal of the direction Chile's security policy will take under his incoming government. No significant security incidents in the last 24 hours.
HIGH. Díaz-Canel rejected the Shield of the Americas framework as neocolonial. The island faces near-total regional isolation within the new coalition structure, continued U.S. pressure, and a fragile energy situation tied to Venezuelan oil. Informal negotiations over minerals-for-sanctions-relief are reported but unconfirmed.
CRITICAL. No new developments in today's OSINT, but the baseline security situation remains the worst in the hemisphere. Gang control of Port-au-Prince neighborhoods, displacement, and near-absence of state authority persist. Haiti was not part of the Shield of the Americas discussion — it remains a humanitarian and security emergency that the coalition framework does not address.
MODERATE. Signed the Shield of the Americas charter. No significant security incidents in the last 24 hours. The DR's participation in the coalition reflects its close U.S. alignment and concern about regional gang and drug trafficking spillover.
MODERATE. President attended the Shield of the Americas summit in Doral. Guyana's oil wealth and proximity to Venezuela make it a natural partner for Washington's regional strategy. No significant security incidents reported in the last 24 hours.
The CJNG succession fight is the most important near-term watch item in the hemisphere. El Mencho built a highly personalized command structure — his enforcer units (Los Deltas, Grupo Elite, CJNG 2000) were loyal to him specifically, not to an institution. What happens next is not a smooth handover. Expect internal fragmentation, violent competition for control of Jalisco and Colima port access, and potential opportunistic moves by Sinaloa Cartel factions in contested border zones like Zacatecas and Guanajuato. The 250 roadblocks were a show of force, but they were also a signal of desperation — cartels don't paralyze their own revenue corridors unless they're trying to demonstrate power they're not sure they still have.
The Shield of the Americas coalition is real on paper but untested operationally. The Ecuador precedent matters — Washington has now demonstrated it will conduct lethal kinetic operations in a partner country on request. That changes the calculus for every other government in the coalition. Expect other leaders to either quietly request similar U.S. support (Peru and Honduras are the most likely candidates given their trafficking exposure) or to feel domestic political pressure from opposition parties who will call the charter a sovereignty giveaway. Watch Colombia specifically — Petro's exclusion from the coalition while his country faces the hemisphere's most complex active armed conflict creates a security gap that neither Washington nor Bogotá can afford to ignore indefinitely.
The Cuba minerals-for-sanctions track is worth watching closely. If the Trump administration is genuinely exploring nickel and cobalt access as the basis for a deal, that would represent a significant departure from decades of Cuba policy — and it would reshape the strategic picture for Venezuela's post-Maduro transition as well, since Havana's security services remain deeply embedded in Caracas. A deal that pulls Cuba toward Washington would accelerate the Venezuela transition. A failed deal could harden Díaz-Canel's posture and drive Havana further toward Beijing.
The CJNG mercury route through Callao to Bolivia is a story that deserves more attention than it's getting. El Mencho's death does not shut down that supply chain — mercury for illegal gold mining is a multi-hundred-million-dollar market, and whoever inherits CJNG's Manzanillo operations will inherit that route too. Peru's election campaign is underway, and illegal mining is barely on the agenda for most parties. That's a governance vulnerability that transnational criminal networks will exploit regardless of who wins in Lima.
