Day 596 — Mexico Peace Index: Biggest Gains in a Decade; 2,377 km Rail Mega-Plan; Sheinbaum Dismisses Trump Intervention Threat

On May 20, 2026 (Day 596, Wednesday), President Claudia Sheinbaum's morning mañanera covered three major topics. MEXICO PEACE INDEX 2026: The Institute for Economics and Peace (IEP) released the Mexico Peace Index 2026, which recorded a 5.1% improvement in peace in 2025 — the most significant single-year improvement in at least a decade and the sixth consecutive year of progress. Total homicides fell 22.7% (approximately 7,000 fewer deaths than 2024), the largest single-year absolute decline on record. Sheinbaum highlighted the data as validation of her security strategy. The IEP report also noted ongoing structural risks: rising disappearances, extortion, and domestic violence indicate that the improvement in lethal violence has not uniformly translated into greater community safety. RAIL INFRASTRUCTURE MEGA-PLAN: Sheinbaum announced ambitious federal plans to construct 2,377 km of new passenger and cargo railway lines, including the Mexico City–Pachuca, Mexico City–Querétaro, Querétaro–Irapuato, and Saltillo–Nuevo Laredo corridors, as well as a Tren Maya cargo extension. The plan also includes major road and water works across 2,300 municipalities. The announcement positions rail infrastructure as a cornerstone of the administration's economic and nearshoring diversification agenda ahead of the USMCA review. TRUMP INTERVENTION DISMISSAL: Sheinbaum addressed reports of U.S. figures seeking to 'intervene' in Mexico, drawing a distinction between statements from some individuals close to Donald Trump and Trump himself, whose position she characterized as more measured. She reiterated the sovereignty principle: Mexico will engage in cooperation but not subordination with any foreign government. NEW SCHOOL DEFENSE (NEM): Sheinbaum defended the Nueva Escuela Mexicana curriculum at the mañanera, stating its goal is to form critical and civic citizens, not rote memorization, and accusing prior administrations of having removed historical figures and national facts from textbooks.
