The Encircled Presidency: Between the Wall and a Sword
A President Between the Sword and the Wall
Mexico's President Claudia Sheinbaum finds herself in an unprecedented geopolitical vise. To her north, the United States has constructed a new military architecture designed explicitly to bypass her government. To her south and across the hemisphere, nation after nation has signed onto that architecture, leaving Mexico increasingly isolated. Within her own borders, cartel violence rages with a ferocity that has transformed entire regions into contested territories where the state's authority is measured not in laws but in body counts.
The question now is not whether Sheinbaum will be forced to make a decision about Mexico's future, but what that decision will be and who will be making it for her.
The Shield of the Americas: A Coalition Built Around Mexico
On March 7, 2026, at the U.S. Southern Command headquarters in Miami, the Trump administration formally launched the Shield of the Americas, operationalized through the Coalition of the Americas Against Cartels (A3C). The coalition centralizes financial intelligence, unifies communications, and activates coordinated patrols under Pentagon supervision. Its stated mission is to confront drug cartels classified as Foreign Terrorist Organizations, with Secretary of War Pete Hegseth declaring: "Wherever they traffic drugs or threaten the American people or our partners, they will be a military target, just as ISIS or Al-Qaeda are".
At least a dozen leaders from Central America, South America, and the Caribbean attended the founding summit. The coalition represents a fundamental shift from traditional law enforcement cooperation, embodied by the DEA, to a hyper-militarized regional defense model whose partners remain outside the decision-making architecture designed by Washington.
Two of the hemisphere's most significant economies while Mexico and Brazil are absent. Their exclusion is not accidental. It reflects ideological divergence with the Trump administration and a rejection of models that compromise national sovereignty. But exclusion has consequences. As the A3C consolidates, Mexico finds itself surrounded by a coalition of nations that have chosen alignment with Washington over regional independence. The pressure to conform will only increase.
The Cartel War Within: A State Losing Its Grip
The external encirclement would be manageable if Mexico's internal situation were stable. It is not.
In Zacatecas, a strategically vital trafficking corridor, violence has escalated dramatically. A car bomb detonated outside police headquarters in Ojocaliente on August 30, 2026, injured at least eleven people and damaged more than sixty homes. The attack, attributed to the Jalisco Cartel New Generation (CJNG), marks the latest escalation in a territorial war with the Mayiza faction of the Sinaloa Cartel. The tactics are evolving: car bombs, explosive-rigged drones, and landmines weapons of war now deployed on Mexican streets. Explosive attacks rose from one incident in 2024 to six in 2025 and ten so far in 2026.
In Sinaloa, the internal war between Los Mayos and Los Chapitos has left more than 3,000 dead in two years. Despite the deployment of over 10,000 military personnel concentrated in Culiacán, violence remains "extremely high". The International Crisis Group reports that cartel factions control "many parts" of the state, where "the authority is a criminal group and not the Mexican state". Fentanyl shipments to the United States continue unabated, demonstrating the "adaptability of criminal markets" even amid internecine warfare.
The most damning revelation concerns political complicity. U.S. prosecutors have formally accused Sinaloa Governor Rubén Rocha Moya of collaborating with Los Chapitos in exchange for bribes. The ICG identifies "protection from political power" as the explanation for the Sinaloa Cartel's enduring strength and the "great pending task" for Mexico in confronting organized crime.
The Renunciation That Revealed Everything
In May 2026, reports emerged that Sheinbaum had placed her resignation on the table during a meeting with former President Andrés Manuel López Obrador in Palenque. According to journalist Mario Di Costanzo, Sheinbaum stated she was being made a "cover or accomplice" of Morena politicians accused by the United States of cartel ties, and that she could no longer operate with any margin of maneuver.
AMLO rejected the resignation, arguing that the only possible substitute, Adán López, was "unpresentable". The meeting reportedly discussed exit strategies for Governor Rocha Moya, including potential asylum in Cuba, Venezuela, Brazil, or Russia or being hidden by the Sinaloa Cartel itself. Whether or not these reports are entirely accurate, they reveal a government under siege. U.S. extradition requests, financial account freezes, and information demands have left dozens of Morena politicians "extremely nervous". The journalist described the Sheinbaum government as hanging by "pins".
Two Paths, One Destination
Sheinbaum faces a narrowing set of options.
Option One: Resistance and Isolation. She can maintain her public stance: "We will not negotiate with criminals" and reject the Shield of the Americas as an infringement on sovereignty. This preserves her ideological consistency and her base's support. But it leaves Mexico encircled by a coalition it refuses to join, facing escalating cartel violence with inadequate institutional capacity, and vulnerable to unilateral U.S. military action justified by the A3C framework.
Option Two: Alignment and Survival. She can pivot toward the coalition, accepting the militarized framework she has publicly rejected. This would require abandoning the remnants of the "abrazos, no balazos" doctrine and embracing the logic of confrontation that Washington demands. It might secure short-term stability and relieve pressure from the north. But it would also mean subordinating Mexican security policy to Pentagon directives, accepting a junior partner status that contradicts Mexico's self-image as a sovereign nation, and potentially fracturing her own coalition as Morena politicians facing U.S. charges seek protection.
The "New America" Proposal: A Provocation or a Blueprint?
Into this volatile landscape, President Trump has introduced a proposal that, on its surface, appears absurd: changing the name of New Mexico to "New America". He has also shared maps depicting Mexico visually integrated into U.S. territory, with the American flag overlaid.
The proposal has been dismissed by New Mexico's governor as a distraction. But the symbolism is unmistakable. Trump has already renamed the Gulf of Mexico as the "Gulf of America" and Lake Ontario as "Lake America". He has suggested that the United States "doesn't need practically anything" from Mexico "spicy tamales, tomatoes, a couple of things, but basically they have nothing we need".
These are not idle provocations. They are signals. Trump is communicating that the current U.S.-Mexico relationship is, in his view, expendable and that a more integrated arrangement, on American terms, is desirable.
My View on the Cartel Question
Let me be clear about where I stand, because neutrality is often misunderstood as indifference.
I am strongly aligned with free trade. The cartels, at their core, are economic actors. They control supply chains, negotiate territorial boundaries, and respond to market incentives. The violence they generate is a function of competition; not inherent to their nature as commercial entities. When cartel leadership maintains discipline, violence is contained. When leadership fractures, as it has in Sinaloa, violence spills into civilian life with devastating consequences.
I am strongly against bad leadership within the cartel ranks not because I oppose their business, but because their failures create the conditions for innocent death. The car bomb in Zacatecas, the thousands dead in Sinaloa, the disappeared young men. These are not the inevitable costs of an illegal industry. Even the implementation of fentanyl for profit is a bad business decision. They are the costs of poor management, internal betrayal, and the absence of enforceable order.
The cartel problem is not that cartels exist. It is that bad leadership has created a security vacuum that the Mexican state is too weak and too compromised to fill. The solution is not more violence. It is better governance, on both sides of the border.
The Path Forward: A Question of Sovereignty and Survival
If Mexico and the United States were to move toward closer integration whether through formal union, economic confederation, or something in between the benefits could be transformative.
The immigration problem would end. Not through walls or deportation, but through the recognition that labor mobility is an economic necessity, not a security threat. A unified North American labor market would formalize what already exists informally.
Free trade would deepen. The USMCA negotiations have already secured tariff exemptions for over 80% of Mexican exports. A more integrated arrangement would eliminate the remaining barriers and create a true North American economic bloc capable of competing with China and the European Union.
The cartel problem would crack. A coordinated, properly funded, and genuinely binational security strategy one that addresses demand, supply, and political corruption simultaneously could dismantle the criminal networks that neither country can defeat alone.
But integration requires trust. And trust requires good faith on both sides.
The Shield of the Americas, as currently constructed, is not an instrument of partnership. It is an instrument of pressure. It surrounds Mexico not to protect it, but to force its compliance.
Sheinbaum's choice is stark: resist and risk isolation, or align and risk subordination. The path she chooses will determine not only her political future, but the future of Mexican sovereignty itself.
