The claim is mostly true because multiple reliable sources confirm that Hungary, led by Prime Minister Viktor Orbán, has officially announced plans to designate Antifa as a terrorist organization following a similar move by former U.S. President Donald Trump, though the characterization of the U.S. Government as a 'fascist regime' is an opinion and not supported by factual evidence.

The timing aligns with former U.S. President Donald Trump's similar announcement earlier in September 2025.
The description of the U.S. Government as a 'fascist regime' is not supported by these sources and reflects an opinion rather than fact.
What the Evidence Shows
Multiple independent and reputable news outlets report that Hungary's Prime Minister Viktor Orbán publicly stated Hungary will designate Antifa as a terrorist organization, explicitly following the precedent set by former U.S. President Donald Trump. This policy announcement occurred in September 2025 and is widely covered by sources such as AP News, CNN, NBC News, Euronews, and others. The designation targets Antifa, described as a loosely affiliated anti-fascist movement with far-left activists. Additionally, Hungary's Foreign Minister has urged the European Union to adopt a similar classification for Antifa.
However, the claim's phrase 'following the decision of the fascist regime in the USA' introduces a subjective and politically charged characterization of the U.S. Government that is not supported by factual reporting or mainstream sources. The U.S. Government under Trump did announce designating Antifa as a terrorist organization, but labeling it a 'fascist regime' is an opinion rather than an established fact.
Therefore, while the core factual claim about Hungary's official designation of Antifa as a terrorist organization following the U.S. Announcement is accurate and well-documented, the additional political labeling in the input is not factual and should be treated separately as opinion.
