Designating four European antifa groups as Foreign Terrorist Organizations

Editor's note: legal analysis documents that the designations do not meet the statute's requirement of a threat to the United States, but no court or official finding establishes them as unlawful.

The countervailing facts come first, because they are substantial. Antifa Ost is a German militant group whose members are accused of attacks on people they identified as part of the right-wing scene between 2018 and 2023 and of a series of assaults in Budapest in early 2023; German prosecutors have charged seven people connected to it, and on September 26, 2025 Hungary added it to its national anti-terrorism list. The Informal Anarchist Federation and International Revolutionary Front has claimed responsibility for bombs and letter bombs aimed at political and economic institutions, including a courthouse. Armed Proletarian Justice claimed a bomb planted near Greek riot police headquarters in December 2023. Revolutionary Class Self-Defense claimed two improvised explosive device attacks, on the Greek Ministry of Labor in February 2024 and on Hellenic Train offices in April 2025. The designations were made under existing statutory authority by the Secretary of State, and a Republican senator had written urging them.

On November 13, 2025 the State Department designated all four as Specially Designated Global Terrorists under Executive Order 13224 and announced the intent to designate them as Foreign Terrorist Organizations under section 219 of the Immigration and Nationality Act, effective November 20. The Treasury's Office of Foreign Assets Control designated them in parallel. The department's own announcement said the designations support the president's National Security Presidential Memorandum-7, an initiative directed at self-described anti-fascism networks, and described the groups as anti-American, anti-capitalist, and anti-Christian. These were the first designations of antifa-affiliated groups abroad. They followed the September 2025 executive order designating antifa a domestic terrorist organization, documented at WLE-15.

Two lines of criticism are on the record. Writing at Just Security, a counter-extremism analyst argued that both authorities require the organization's terrorist activity to threaten the security of United States nationals or the national security of the United States, and that nothing in the State Department's own factual basis satisfies that criterion; the Attorney General had called antifa an existential threat to the nation and the Homeland Security Secretary had likened its network to ISIS and Hezbollah. Separately, counsel at Arnold and Porter advised clients that the designations sharpen compliance risk for American tax-exempt organizations, because material-support liability and strict-liability sanctions exposure reach U.S. persons, and financial institutions tend to close accounts at the first sign of association. This record is Tier B. The underlying violence is real, the process was the ordinary one, and no court has reviewed the designations. What is documented is the designation, its stated purpose, and the criticism of both.
