Day 599 — Sheinbaum Condemns Israeli Interception of Gaza-Bound Flotilla as 'Unjustifiable Aggression'; Questions Chihuahua-Texas Security Agreement

On May 23, 2026 (Day 599), the Sheinbaum administration issued two significant sovereignty-related statements. FLOTILLA CONDEMNATION: Sheinbaum condemned Israel's interception of the Global Sumud Flotilla in international waters — a humanitarian convoy heading to Gaza — calling the act 'una agresión injustificable' (an unjustifiable aggression). Three Mexican women were aboard the vessel: Violeta Núñez, Sol González Eguia, and Paulina del Castillo Poblano. Israeli forces detained the convoy and its passengers; the three Mexicans were subsequently released and transferred to Istanbul, Turkey. Sheinbaum stated Mexico's position is 'always the defense of human rights, anywhere' and called for accountability for the interception. This marks Mexico's sharpest public condemnation of Israeli military actions since the presidency began — consistent with Mexico's historical abstentionist or condemnation stance in the Israel-Palestine conflict at the UN General Assembly. CHIHUAHUA-TEXAS AGREEMENT: Separately, Sheinbaum publicly questioned the legality of a 2022 bilateral agreement signed between Chihuahua state (Governor Maru Campos, opposition PAN) and the U.S. state of Texas on migration, security, and intelligence matters. She described it as 'está raro' (seems odd) that two state governments would sign an accord covering matters that are constitutionally reserved for the federal government in Mexico, and called for a review of 'how far' the agreement reaches and whether it constitutes a violation of Mexican national sovereignty. The concern is directly linked to the April 20, 2026 CIA-Chihuahua incident — where two CIA agents died in an unauthorized joint drug-lab operation that the federal government was not notified of — and reflects the administration's ongoing probe of unauthorized federal intelligence cooperation between Chihuahua and U.S. agencies. CONTEXT: The Petrobras-Pemex MOU announcement from the May 22 mañanera was also picked up by Mexican media over the weekend: Sheinbaum confirmed the two state oil companies are finalizing a cooperation agreement covering deep-water exploration in the Gulf of Mexico and mature field exploitation, to be signed in June 2026. The initiative came at the proposal of Brazilian President Lula da Silva.
