The National Jewish Assembly and We Believe in Israel unequivocally welcome the Argentine government’s decision to designate chapters of the Muslim Brotherhood as terrorist organisations.
Argentina’s action reflects a clear-eyed recognition of the Muslim Brotherhood’s transnational role in promoting extremist ideology, facilitating terrorist networks, and undermining democratic societies from within. As President Javier Milei’s government has made clear, this decision is grounded in intelligence assessments identifying illicit activity, public incitement to violent extremism, links to other terrorist organisations, and the tangible national security risks these networks pose.
By adding Muslim Brotherhood entities to Argentina’s terrorism and financing registry, the government has taken a decisive step to strengthen prevention, disrupt funding streams, and reinforce international cooperation with democratic partners including Israel and the United States.
This move strongly validates the core case set out in our recent joint press release ahead of our forthcoming campaign which will include a parliamentary briefing and a coordinated, multi-pronged effort to demand that the British government act with similar clarity. That campaign will call for the full proscription of the Muslim Brotherhood in its entirety, using existing powers under the Terrorism Act, rather than continued ambiguity, partial measures, or indefinite review.
Our position is clear: selective or piecemeal approaches allow extremist movements to adapt, rebrand, and continue operating through affiliated bodies. Comprehensive proscription is not symbolic. It is a practical tool that enables law enforcement, regulators, and civil society to disrupt radicalisation, financing, and organisational infrastructure more effectively.
Steve Winston, Managing Director of the National Jewish Assembly, said:
“The UK should pay close attention to what Argentina has just done. Hesitation leaves Britain exposed to the same ideological networks and destabilising forces this move is meant to stop. Confronting extremism requires political backbone, legal consistency and moral clarity. Argentina has shown all three. Britain should do the same.”
The National Jewish Assembly and We Believe in Israel will continue to work with parliamentarians, policymakers, and partners across civil society to press for robust, evidence-based action to defend democratic values, protect communities, and uphold the rule of law.
