If this is constitutional the First Amendment means nothing. From Natylie Baldwin at antiwar.com:
Establishment institutions usually start their implementation of censorship and the throttling of press freedom by going after individuals and outlets that are small and/or not well liked by a cross-section of the public. The obscurity or general unpalatable nature of the target ensures the success of setting the precedent.
Most Americans have probably never heard of Strategic Culture Foundation (SCF) and many would be unsympathetic once they learn that the U.S. government claims it is a think tank and journal associated with Russian military intelligence, although no evidence is offered to back up this assertion, and SCF denies it has ties to the Russian government. But years of anti-Russia sentiment in the political sphere and in most American media ensures that the claim alone will suffice to tar any Americans associated with Strategic Culture Foundation with a black brush.
I have confirmed that two American writers for SCF have received letters from the US Treasury Department in recent weeks warning them of fines of over $300,000 if they continue to write for the journal. These threats are in response to alleged Russian interference in the 2020 US election and part of the US government’s enforcement of Executive Order 13848 signed by President Donald Trump in September of 2018 which sought to ascertain foreign interference in any future elections in the US and to punish those deemed guilty. Threats to US elections included not only tampering with actual voting and its supporting infrastructure but “covert distribution of propaganda and disinformation.”
Journalists should be able to publish in the U.S. regardless of who they work for. This is an absolute travesty. From Finian Cunningham at strategic-culture.org:
Washington’s real objective is to criminalize critical journalism and indeed any form of critical dissent.
In an audacious attack on free speech, journalists and writers based in the United States have now been banned by the U.S. federal authorities from publishing articles with Strategic Culture Foundation. We interview one of those authors affected by the ban, New York City-based journalist Daniel Lazare who shares his thoughts on the profound implications for free speech, independent journalism and political dissent.
Lazare is one of several U.S.-based writers who formerly published regular columns with Strategic Culture Foundation. Our online journal greatly appreciated their intelligent insights and analysis of U.S. and international politics. Sadly, we will no longer be able to publish their columns because of the threat levied on them by the U.S. federal authorities who accuse SCF of being an influence operation directed by the Kremlin. The allegations and threats are baseless and draconian.
If U.S.-based writers defy the ban, they have been threatened with astronomical financial penalties of over $300,000. The prohibition has only emerged in recent weeks. It follows earlier moves by the U.S. State Department and the Treasury Department accusing SCF of being an agent of Russian foreign intelligence. No evidence has been presented by the U.S. authorities to support their provocative claims. The Editorial Board of SCF categorically dismisses the allegations. In a statement, the editors said: “We reject all such claims by the U.S. authorities that the journal is an alleged Russian intelligence operation. We have no connection with the Russian government. We provide an independent forum for international writers to debate and freely critique major topical issues of world importance.”
