Executive Summary
Mexico’s government said Nemesio Rubén Oseguera Cervantes, the Jalisco cartel leader known as “El Mencho,” was killed on Feb. 21 in an operation aided by U.S. intelligence, unleashing a wave of coordinated reprisals that left dozens dead and paralyzed parts of the country. In Washington, President Trump moved to reimpose a broad 15 percent tariff under a different statute after the Supreme Court, in a 6–3 ruling, struck down his earlier tariff regime and opened the door to as much as $175 billion in refunds, jolting trading partners already bracing for retaliation. At the same time, Mr. Trump pressed advisers for more forceful options against Iran even as senior military officials urged caution, a debate that has revived fears of disruption in the Strait of Hormuz, through which roughly a fifth of the world’s crude oil flows. Elsewhere, Russia marked the war’s fifth year with renewed strikes on Ukrainian cities and mounting evidence of long-term devastation, while The Hague opened pre-trial hearings that could put the former Philippine president Rodrigo Duterte on a path to trial for crimes against humanity.

Mexico Says It Killed El Mencho; Cartel Reprisals Spread
Mexican security officials said on Feb. 21 that federal forces killed Nemesio Oseguera Cervantes, the leader of the Jalisco New Generation Cartel, during an operation near Tapalpa, Jalisco, an event the authorities described as a major blow against a group blamed for some of the country’s worst violence and for trafficking fentanyl into the United States. The Mexican defense secretary, Gen. Ricardo Trevilla Trejo, said the government tracked the cartel leader through an associate linked to one of his romantic partners, and that Mr. Oseguera died of injuries after a confrontation as he was being transported.
American officials publicly embraced the operation, underscoring the Trump administration’s push to treat major cartels as national-security threats. White House press secretary Karoline Leavitt said the United States supplied intelligence that helped Mexico locate the cartel leader, whom the United States had offered a $15 million reward to capture. The CJNG was designated a Foreign Terrorist Organization by Washington last year, elevating expectations of closer U.S.-Mexico coordination, and raising Mexican sensitivities over sovereignty that have flared during past cross-border security debates.
Within hours, Mexican officials and local media described reprisals on a scale that tested the state’s ability to reassert control. Authorities reported at least 250 roadblocks across roughly 20 states, with heavy concentrations in Jalisco, and a rash of arsons and attacks that damaged banks, supermarkets and gas stations, halted public transport and prompted flight cancellations in Guadalajara and Puerto Vallarta. Early casualty figures varied across reports, with some officials citing at least 25 deaths and others putting the toll above 70, including security personnel and suspected cartel members; the government said it deployed 10,000 troops and carried out dozens of arrests. It is unclear how quickly the CJNG will consolidate leadership after the death of its founder, or whether the group’s retaliation is meant to deter further decapitation strikes by signaling that, even without its top boss, it can still shut down entire regions.
Trump Presses Iran Strike Options as Advisers Warn of Escalation
President Trump has been pushing advisers for a military option against Iran that he believes could force Tehran back to negotiations, according to people familiar with internal discussions, even as senior military officials cautioned that a “decisive” one-off strike is unlikely and could entangle the United States in a broader conflict. The debate has unfolded as the United States increases its military presence in the region while beginning a withdrawal from a key base in northeastern Syria, redeploying forces to northern Iraq—moves that can be read as consolidation rather than retrenchment, though the administration has also weighed a fuller Syria drawdown.
The chairman of the Joint Chiefs of Staff, Gen. Dan Caine, has warned in private settings that limited strikes could trigger Iranian retaliation and a prolonged campaign, those people said, a view that reflects long-standing Pentagon skepticism about the idea that a short, surgical action can reset the regional balance. Mr. Trump publicly rejected reports that General Caine opposed military action, writing that the general “has not spoken of not doing Iran” and suggesting that any conflict would be “easily won” if ordered. The White House referred questions to the president’s posts, and a senior military official said planners were providing “unbiased” advice.
Diplomats around Mr. Trump have urged him to give talks more room. Jared Kushner and Steve Witkoff, two envoys involved in regional diplomacy, have argued that any nuclear deal may require the president to moderate some demands, according to people familiar with their counsel. Critics, including some lawmakers, have raised constitutional concerns about a momentous decision being made largely inside the executive branch, with Congress playing a limited role. The most immediate unknown is whether the administration is using the threat of force mainly as leverage, or whether the president is prepared to order a strike even if military leaders believe it will not remain limited.
Strait of Hormuz Fears Grow as Markets Appear Complacent
The administration’s Iran debate has sharpened anxieties in energy markets about the Strait of Hormuz, the narrow maritime passage that carries roughly 20 percent of the world’s crude oil each day. Iranian officials have periodically threatened to disrupt shipping there in response to sanctions or military pressure, and analysts say even a temporary disturbance—through harassment of tankers, mining, or missile attacks on regional infrastructure—could send prices sharply higher and drive up insurance costs for cargo.
India, which imports about 90 percent of its crude oil and receives more than 40 percent of its supplies from West Asia via the Strait, has been exploring alternative supply routes and reinforcing contracts, according to reports citing energy officials and industry executives. Analysts have warned that each $10 jump in crude could add billions to India’s import bill, with spillovers to inflation and currency stability. Alternative pipelines in the region, including routes that bypass the strait, have capacity but not enough to replace the volume that normally transits the chokepoint.
Yet some market participants appear to be pricing in restraint. Several analysts attributed that calm to a belief that Mr. Trump ultimately prefers coercive bargaining to open-ended war, and to the assumption that Gulf producers and the U.S. Navy would move quickly to keep lanes open. That confidence may be overstated: Iran has a record of operating in the gray zone—seizing vessels, using proxies and drones, and calibrating pressure below the threshold of full-scale conflict. A central question now is whether rising U.S. force posture and Iranian signaling are converging toward deterrence, or toward miscalculation.
Ukraine Enters Fifth Year as Attacks Hit Cities and Power Grid
Russia’s full-scale invasion of Ukraine entered its fifth year with renewed missile and drone strikes that Ukrainian officials said killed civilians in Kyiv and Lviv and further strained an energy system repeatedly targeted through the winters. President Volodymyr Zelensky accused Russia of “terror” after an attack in Lviv killed a policewoman and wounded at least two dozen others, while officials in the Kyiv region reported at least one death and injuries that included children. Ukraine’s air force said it intercepted a significant share of the incoming weapons, part of a pattern in which air defenses limit but do not eliminate the damage.
The scale of Ukraine’s long-term burden has become harder to ignore. The World Health Organization has verified more than 2,800 attacks on health-care facilities since 2022, and the United Nations has estimated that about one-fifth of the country is contaminated by mines and unexploded ordnance. The World Bank has projected reconstruction costs exceeding $588 billion over the next decade, a figure that assumes fighting eventually subsides rather than intensifies.
Diplomatic contacts have continued in narrow channels, including military-to-military discussions over front-line protocols and disengagement, sometimes mediated by the United States. Serhii Kyslytsia, a Ukrainian negotiator, described the talks as “business-like,” but said he doubted Russian interlocutors could reliably report battlefield realities. On the Russian side, recruitment incentives have become more visible in smaller cities, and new accounts—some carried by the BBC—have described commanders allegedly executing soldiers who refused orders or balked at what troops called “meat storms,” claims that could not be independently verified. Together, the battlefield attrition and the reported internal coercion suggest a conflict that is devouring resources and manpower without producing a clear path to resolution.
Pakistan Strikes Afghan Border Areas, and Kabul Threatens Retaliation
Pakistan carried out airstrikes early Sunday in Afghanistan’s Nangarhar and Paktika provinces, saying it hit seven militant camps and killed at least 70 fighters from the Pakistan Taliban, or TTP, and affiliated groups. Islamabad cast the operation as a “retributive response” to attacks inside Pakistan, including a suicide bombing in Islamabad that killed 36 people and was claimed by the Islamic State Khorasan Province, or ISKP.
Afghan authorities rejected Pakistan’s account, saying the strikes hit civilian areas, including a religious school and homes, and killed or injured at least 18 people, among them women and children. The Afghan Ministry of Defense called the strikes “a breach of international law and the principles of good neighborliness” and said it would deliver a “measured and appropriate response.” The two sides had agreed to a ceasefire in October 2025, and the new strikes now test whether that framework still has meaning.
Pakistan’s information minister, Attaullah Tarar, said the attacks were “intelligence-based, selective operations,” and President Asif Ali Zardari said they were “rooted in [Pakistan’s] inherent right to defend its people against terrorism.” India condemned the airstrikes, with a foreign ministry spokesman, Randhir Jaiswal, calling them “another effort by Pakistan to externalize its internal failures” while reiterating support for Afghanistan’s sovereignty. The escalation adds to a volatile mix along the border, where multiple militant factions operate and where each side accuses the other of harboring proxies—an accusation that, over time, has made even limited cross-border actions difficult to contain.
ICC Begins Duterte Hearings, Testing Limits of International Justice
The International Criminal Court opened pre-trial hearings in The Hague for Rodrigo Duterte, the former Philippine president, on accusations of crimes against humanity tied to his brutal “war on drugs.” Prosecutors said Mr. Duterte was “pivotal” to a campaign of extrajudicial killings that they allege spanned his tenure as mayor of Davao City and later his presidency, from 2011 through 2019, and involved thousands of deaths. The indictment cites involvement in at least 76 to 78 murders, which prosecutors said represent only a fraction of the alleged toll.
Mr. Duterte has refused to recognize the court’s jurisdiction and waived his right to appear, with his defense citing frailty and insisting on his innocence. His lawyer said he “stands behind his legacy resolutely,” a line aimed as much at domestic political audiences as at the judges in The Hague. The Philippines withdrew from the Rome Statute in 2018, but the court argues it retains jurisdiction over alleged crimes committed while the country was a member.
The judges are expected to review evidence over four days and decide within 60 days whether the case should proceed to trial. The proceedings have drawn protests outside the court from victims’ families and rights advocates, while Mr. Duterte’s supporters have argued that the campaign, however harsh, was aimed at public safety. It is unclear how President Ferdinand Marcos Jr.’s government will position itself if the court advances the case, particularly if enforcement steps are sought in a region where the ICC has struggled to secure custody of suspects without state cooperation.

Supreme Court Ends IEEPA Tariffs; Trump Pivots to 15% Levy
The Supreme Court ruled 6–3 on Friday that President Trump’s earlier tariffs imposed under the International Emergency Economic Powers Act, a 1977 national-security law, exceeded presidential authority, dealing a sharp blow to a cornerstone of his trade strategy. The court held that while IEEPA allows presidents to regulate commerce in emergencies, it does not authorize the levying of tariffs—an authority the Constitution assigns to Congress. U.S. Customs and Border Protection said it would stop collecting the IEEPA-based duties by Tuesday morning.
The decision could make more than $175 billion in previously collected duties eligible for refunds, potentially setting off a wave of claims from importers and adding another fiscal complication to an already contentious trade agenda. The ruling also undercut deals struck with several Asian partners who had accepted specific duties in exchange for relief from threatened increases, leaving governments in Indonesia, Malaysia and Vietnam questioning whether any negotiated tariff arrangement with Washington can survive a court challenge.
Mr. Trump responded by invoking Section 122 of the Trade Act of 1974 to impose a new 15 percent tariff on most imports, a tool that allows unilateral action for up to 150 days. He warned trading partners against “exploiting” the Supreme Court’s decision and floated the idea of using tariff revenue for direct payments to Americans, suggesting the program might not require congressional approval—an assertion that legal scholars say would almost certainly invite further challenges.
Financial markets, already rattled by the legal reversal and the sudden pivot, have been forced to price not just higher costs but higher uncertainty: whether refunds will be paid swiftly, whether the new tariff will face injunctions, and whether major trading partners will retaliate. The immediate fight, in other words, has shifted from the tariff rate itself to the durability of the president’s legal authority—and the willingness of courts and Congress to constrain it.
AI & Technology
Nvidia’s Rally Defies a Slumping Tech Sector as ‘Physical AI’ Takes Hold
Nvidia’s shares continued to climb this week, extending a rally that has made it the world’s most valuable technology company even as parts of the broader tech sector have sagged. In Asia, the Hang Seng Tech Index has been under pressure, dragging down heavyweight names like Tencent and Alibaba, and highlighting a widening gap between investors’ enthusiasm for the infrastructure of artificial intelligence and their caution about consumer and platform businesses facing slower growth and regulatory risks.
Jensen Huang, Nvidia’s chief executive, has been amplifying a message that Wall Street has rewarded: that the next phase of A.I. will move beyond text and image generation into machines that operate in the physical world. He has repeatedly described the coming era as “physical A.I.,” a shorthand for systems that can perceive, plan and act—technology that proponents say could accelerate humanoid robots and other adaptable machines for factories, logistics and home care. The idea has helped investors imagine a larger market for Nvidia’s chips than data centers alone.
But the story has a less glossy underside, one that critics say the market often discounts. Reports highlighted by MIT Technology Review have pointed to the vast human labor required to train and validate robotic systems, including repetitive data gathering and demonstrations that can be outsourced, underpaid and opaque. The companies building robotics platforms argue that human feedback is a transitional cost on the way to more autonomy, and that safer, more reliable machines require rigorous real-world testing.
For now, Nvidia’s ascent has become a proxy bet on whether A.I. expands into an economy of embodied machines, not just digital assistants. The open question is whether “physical A.I.” becomes a mass market soon enough to justify the valuations forming around it—or whether the sector’s next correction will come not from technological limits but from the slower, messier realities of deployment, labor and regulation.

South Korea Seeks Space Between Washington and Beijing
South Korea has signaled a desire to keep its alliance with the United States from becoming a front-line platform for confrontation with China, lodging a protest with U.S. Forces Korea after a brief aerial face-off between American and Chinese fighter jets in the Yellow Sea last week. Analysts interpreted Seoul’s démarche as an unusually explicit reminder that while it relies on U.S. security guarantees, it also has deep economic exposure to China and wants to limit the risk of being pulled into a U.S.-China clash by accident.
Seoul is also reported to be seeking to scale back aspects of “Freedom Shield,” its upcoming joint exercise with the United States, by reducing large troop and equipment deployments and spreading training throughout the year. South Korean officials have portrayed the idea as a way to lower temperatures with North Korea and reopen diplomatic channels that have been largely closed since 2019. American officials, according to reports, have been skeptical, arguing that visible readiness is a deterrent and that past reductions were difficult to reverse.
China, meanwhile, has been reinforcing ties with North Korea, with Xi Jinping congratulating Kim Jong-un on his re-election and expressing a desire to open a “new chapter” in relations. For Seoul, the balancing act is increasingly narrow: it wants U.S. protection against the North, room to trade with China, and enough autonomy to pursue its own approach to diplomacy—without giving either Washington or Beijing reason to doubt its reliability.
Chad Closes Sudan Border After Soldiers Killed in Spillover Fighting
Chad said on Monday that it had closed its eastern border with Sudan “until further notice” after clashes in the border town of Tina killed five Chadian soldiers, a sign of how Sudan’s civil war is destabilizing neighbors far beyond Khartoum. The conflict, which began in April 2023 between the Sudanese Armed Forces and the Rapid Support Forces, has repeatedly spilled into peripheral regions, pushing refugees and armed groups across porous frontiers.
Chadian officials said the closure would include humanitarian exceptions with prior approval, an effort to balance security with the reality that Chad hosts nearly one million Sudanese refugees. The move may also reflect fears that localized clashes could evolve into something more entangling, especially if armed factions use Chadian territory for transit or resupply, or if cross-border raids provoke reprisals.
Diplomats and aid groups have warned that sealing borders can redirect displacement rather than halt it, and can complicate the delivery of food and medical support in places where formal crossings are often the safest corridors. With Sudan’s war showing little sign of resolution, Chad’s decision suggests the conflict is shifting from a national catastrophe to a regional one—one border closure at a time.

Agentic coding: “ship faster” collides with “don’t hand over root”
A clear tension is forming between developers optimizing for speed and others warning that the new default is dangerously broad access: @levelsio bragged about skipping permissions to move “100x faster,” while @tobi framed “vibecoding” as the antidote to waiting on tooling ecosystems. The skepticism is sharper from @elonmusk, and even consumer-tech anecdotes like @garrytan (people contorting setups to avoid vendor apps) reinforce how trust and control are becoming core product features.

AI productivity and the labor-market argument: displacement vs Jevons vs leisure
An emerging consensus among builders is that higher output won’t reduce headcount because demand for software is effectively unbounded: @AndrewYNg argued developers will operate at higher abstraction and that “X Engineer” roles will proliferate. @fchollet similarly leaned on Jevons-style logic (efficiency increases demand), while @tobi boosted the alternative “maybe we just take the productivity dividend as time” view (e.g., a four-day week).
Benchmarks are back, but “skill” still isn’t “general intelligence”
Excitement around benchmark performance is rising again—@paulg amplified claims of an ARC-AGI-2 “saturating” result with per-task economics, fueling a sense that capability progress is becoming operationalized. Against that, @fchollet reiterated a core caution: strong task performance doesn’t imply general intelligence, pushing back on over-reading single metrics.

Claude/Cobol narratives: “automation shock” meets public-market positioning
Legacy-code automation became a market story as well as a technical one: @levelsio spotlighted the claim that Claude can streamline COBOL—framed alongside IBM’s sharp drawdown—and then pivoted to “who owns Anthropic” as a public-equity way to express the trade. In parallel, @naval circulated a biting take on AI lab value creation/appropriation dynamics, reflecting simmering anxiety about moats, IP leakage, and who captures the surplus.
Stablecoins as the “new payments UX,” plus crypto’s moral framing
The crypto-finance thread stayed focused on payments pragmatism: @brian_armstrong presented stablecoins as a cleaner baseline for moving money, and he tied the case for crypto to distributional politics by calling inflation a regressive tax on cash-holders @brian_armstrong. Separately, his builder outreach @brian_armstrong underscored how much of the ecosystem narrative is “show me what’s shipping,” not abstract ideology.
Attention, mindset, and “performance philosophy” as a tech leader preoccupation
Several voices leaned into cognitive control as a competitive advantage: @naval warned that attention will be “directed for you” if you don’t steer it, while @dhh argued pessimism is a modifiable disposition with real health consequences and urged a Stoic locus-of-control reset. The tone here is less self-help than operational—treating focus and optimism as trainable inputs to output.

Iran: “historic transformation” framing meets on-the-ground protest signals
Geopolitical commentary clustered around regime-change expectations and protest momentum: @wolfejosh elevated Reza Pahlavi’s message that Iran is at the edge of a historic shift, framing it as a threshold moment. He also amplified reports of student uprisings and suppression @wolfejosh, creating a two-track narrative of top-down political messaging plus bottom-up campus mobilization.
