The @StateDept , supported by Pacific Northwest National Laboratory partnered with @Marocdiplo_EN and @FAR_Maroc_ to bring practitioners from 10 African States Parties to the Chemical Weapons Convention (CWC) to participate in “Atlas,” a three-day tabletop exercise focused on preventing, detecting, and responding to chemical terrorism threats. Through interactive discussions and exercises, and under guidance from a diverse set of experts, notably from the Organization for the Prohibition of Chemical Weapons @OPCW, participants explored ways to strengthen cooperation and preparedness to address evolving chemical security challenges in a modern-day setting.

Thanks to Amelie Klussman, Security Policy Director at Germany’s MFA, for today’s discussion. Built on the foundation of NATO extended nuclear deterrence, Germany’s reindustrialization and increased defense spending are key to advancing NATO 3.0.

Signing a Strategic Civil Nuclear Cooperation MOU with Paraguay is just another step in the continued growth of our relationship between our two countries. We’ve always had strong links between the United States and Paraguay, and now, those links are even stronger.

As a co-founder of the Nuclear Forensics International Technical Working Group, @NNSANews attended the 29th Plenary meeting in Berlin alongside @FBI and @StateACN.
International collaborations contribute to American capability to prevent nuclear threats and hold perpetrators accountable.

Proud to see X-ray cargo scanners the U.S. Mission donated to Tangier Med Port helping strengthen security at one of the world's most strategic trade hubs.
Together with trained operators, these scanners enhance Morocco's ability to detect illicit weapons, dual-use components, and other dangerous cargo, advancing our shared commitment to security, safe trade, and our enduring U.S.-Morocco partnership.

I’ve designated the Ecuadorian gang Chone Killers as a Foreign Terrorist Organization and Specially Designated Global Terrorist. Ecuadorian gangs help Mexican cartels move and export illicit drugs to fund terrorism and criminal activity. The Chone Killers have attacked civilians, law enforcement officers, and government officials, including high profile assassinations of public officials.
Working with President @DanielNoboaOk in Ecuador, we will continue to strengthen our regional security and ensure narcoterrorists have no place in our hemisphere.

Through Operation Economic Fury, we continue to disrupt procurement networks that support the Iranian regime’s military programs and its military activities in the region. Today the United States sanctioned 13 individuals and entities based in Iran, Belarus, and China who sought to source and purchase weapons on behalf of the Islamic Revolutionary Guard Corps.

Hoy tuve el honor de inaugurar la conferencia regional del programa FIRST en Buenos Aires, junto a representantes del gobierno de los Estados Unidos y a delegaciones de toda América Latina y el Caribe.
Que la Argentina sea sede responde a una decisión clara de este Gobierno: revalorizar el sector nuclear, tomar una posición de liderazgo en la región y allanar el camino para inversiones estratégicas en nuevas tecnologías como los Small Modular Reactors (SMR).
Sobre una base de una economía ordenada y estabilidad jurídica, nuestro país aporta algo que se construye con el tiempo: más de setenta años de experiencia nuclear. Argentina domina el ciclo de combustible nuclear, opera centrales nucleares, exporta reactores de investigación y tiene una industria de proveedores calificados para toda la cadena de valor. Un inversor que mira a la Argentina encuentra un ecosistema consolidado, con ingeniería, recursos humanos formados y un regulador con trayectoria reconocida en seguridad y no proliferación.
El sector nuclear atraviesa un momento bisagra y las inversiones que se determinen ahora marcarán el rumbo por mucho tiempo. Argentina tiene que ser protagonista de esa conversación a nivel regional. Eventos como este son, justamente, donde esas oportunidades empiezan a tomar forma para nuestro país.

Comenzó el cuarto taller regional anual para América Latina y el Caribe del programa FIRST, coorganizado por la Comisión Nacional de Energía Atómica (CNEA) y el Departamento de Estado de los Estados Unidos, y tiene como objetivo promover el despliegue responsable de la tecnología de reactores modulares pequeños (SMR) bajo los más altos estándares internacionales de seguridad y no proliferación. Argentina se convirtió en el primer país de América Latina en incorporarse a esta iniciativa en calidad de socio durante 2025.
Durante la primera jornada, el Presidente de la CNEA, Ing. Martín Porro, realizó una presentación sobre las capacidades argentinas en el campo de los SMR y la posibilidad de brindar servicios, ingeniería y asesoramiento a la región.
La realización de este taller en el país consolida a la Argentina como un referente regional en el desarrollo de reactores modulares pequeños, así como también reconoce su trayectoria de más de siete décadas en el uso pacífico de la energía nuclear y su capacidad para acompañar a los programas emergentes de América Latina.
La apertura de las jornadas contó con la participación del Secretario de Asuntos Nucleares argentino, Dr. Federico Ramos Napoli; el Embajador de los Estados Unidos en la Argentina, Peter Lamelas; el Subsecretario de Estado para Control de Armas y No Proliferación de Estados Unidos, Christopher T. Yeaw; y el Consejero Político de la Embajada de Canadá, Jonathan Sauvé.

Honored to mark Malta’s entry into the Registry Information Sharing Compact, or RISC, a key tool for maritime security and countering sanctions evasion. Malta strengthens RISC’s impact at a time when hostile states, armed robbers, hijackers, and organized crime syndicates exploit commercial maritime systems and undermine the international order. This signing marks a new high in U.S.-Malta relations. The United States values Malta’s leadership in maritime security and sanctions evasion prevention. I applaud Malta’s accession to RISC and look forward to deepening cooperation that supports our national security and Malta’s borders by strengthening information sharing and enhancing sanctions compliance.

SHAMEFUL. How does the NUCLEAR Non-Proliferation Treaty conference elect Iran as one of its 34 VPs, when the IAEA says Tehran has 400+ kg of 60% enriched uranium?? — accumulating a stockpile for which it has no credible, conceivable civilian justification??
This is exactly the kind of nonsense that makes Americans roll their eyes at multilateral institutions.
Iran shouldn’t be given any cover for its dangerous behavior.
