Leaders representing major Jewish community organizations from the United States, the United Kingdom, Canada, France, Germany, Australia, and Argentina convened in London on Monday for a multi-day summit aimed at addressing the global rise in antisemitism. The gathering, organized by the J7 Large Communities’ Task Force Against Antisemitism, focused on coordinating international strategies related to policy, security, education, and technology to combat antisemitic incidents worldwide.

The J7 coalition responded to increasing antisemitic violence and hostility, highlighting findings from their latest annual report showing 2025 as the deadliest year for Jews living outside Israel since 1994. The report noted a marked rise in antisemitic incidents in several countries, including the United Kingdom.

On Monday, delegates met with British Foreign Secretary Ed Miliband to discuss the UK government’s role in addressing antisemitism under the leadership of Andy Burnham. The task force expressed concerns over recent government measures and rhetoric concerning Israel, emphasizing how such discourse adversely affects Jewish communities domestically and abroad. They also highlighted the expanding threat of online hate speech, the influence of the Iranian regime and its proxies, and the persistent demonization of Israel in public and political spheres, which frequently serves as a conduit for antisemitic behavior.

Miliband condemned the motion against Zionism passed at the Green Party conference, describing it as abhorrent, and reaffirmed the UK’s commitment to the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism. The meeting concluded with a proposal for establishing an international ministerial task force on antisemitism, which Miliband agreed to help launch.

Jonathan Greenblatt, CEO and National Director of the Anti-Defamation League (ADL), described the discussions as constructive, acknowledging areas of disagreement but underscoring shared concerns over anti-Zionist rhetoric, harassment of the British Jewish community, and the growing threat of AI-enabled antisemitism online. He indicated the dialogue would continue with calls for sustained governmental accountability.

Concurrently, UK Interior Minister Shabana Mahmood announced a public inquiry into the murders of Adrian Daulby and Melvin Cravitz, who were killed in a terror attack at the Heaton Park Synagogue in Manchester on Yom Kippur in October 2025.

Following the London summit, the J7 delegation traveled to Dublin on Tuesday, where they gathered in Herzog Park—a site named after Israel’s sixth president and former chief rabbi of Ireland, Chaim Yitzhak HaLevi Herzog—to show solidarity with the Irish Jewish community. The park recently attracted national attention after a proposed attempt to remove Herzog’s name was met with public opposition and shelved.

Maurice Cohen, chairman of the Jewish Representative Council of Ireland, addressed the group, underscoring the small yet historically rooted nature of Ireland’s Jewish population and expressing concern over 143 recorded antisemitic incidents between July 2025 and January 2026. Cohen called for more than verbal condemnations, urging practical security measures, political leadership, and unequivocal recognition that antisemitism has no place in Irish society.

Jonathan Greenblatt reiterated the task force’s concern over escalating antisemitic rhetoric in Ireland, noting that while Ireland is not a J7 member, the coalition included a special chapter on the country in its report based on data provided by the Jewish Representative Council of Ireland. He stressed the urgent need for dedicated security funding and consistent enforcement of hate crime laws, warning against waiting for a tragedy before implementing preventative actions.

During their visit in London, the J7 group also engaged with the Union of Jewish Students and the Community Security Trust, which offers security services and advocacy for the UK Jewish community. Further meetings with government representatives and Jewish leaders were scheduled to continue throughout the week to advance collaborative efforts against antisemitism.
