Brazilian Navy Authorization for Visit of Iranian Warships Causes New Diplomatic Strain After Two Years
The visit of two Iranian warships to Brazil, which took place between January 23 and 30, 2023, has resurfaced on social media following the reemergence of a fake news story claiming that Iran came to seek enriched uranium on Brazilian territory.
The claim was denied by official bodies but reignited the debate over the true objectives of the Iranian mission and the diplomatic impact of the Brazilian government’s decision at the time.
The ships IRIS Makran and IRIS Dena docked at the Port of Rio de Janeiro with official authorization, prompting public protests from U.S. Ambassador Elizabeth Bagley and criticisms from Israel, which classified Iran as a “malign state.”

All investigations, official statements, and international reactions occurred still in 2023, but resurfaced in June 2025, when videos of U.S. Senator Ted Cruz began circulating again in posts that distort the facts and suggest links between Brazil and the Iranian nuclear program.
Iranian Warships in Brazil Rekindle International Debate on Security and Sovereignty
The arrival of the helicopter carrier IRIS Makran and the frigate IRIS Dena in Brazilian waters was confirmed by the Port Authority of Rio de Janeiro on February 26, 2023, with a stay authorized until March 4.
The visit, classified as “friendly” by the Brazilian government, generated a strong reaction from U.S. authorities. Elizabeth Bagley stated that these ships “facilitated illicit trade and terrorist activities.”
Although the visit was authorized by the Brazilian Navy, the diplomatic reception contrasted with the tension behind the scenes.
According to telegrams obtained via the Freedom of Information Act, there was intense movement between the Ministry of Foreign Affairs, Comptroller General of the Union, and international journalists seeking answers.
U.S. Senator Ted Cruz classified the docking as a “direct threat to American security” and warned of possible crippling sanctions on the Port of Rio de Janeiro and Brazilian companies involved.
Speculations About Uranium and Espionage Place Brazil Under Suspicion of Cooperation with Tehran
In June 2025, a video with unfounded accusations that Brazil had exported enriched uranium to Iran resurfaced on social media.
The allegation was promptly denied by the Presidential Communications Secretariat, which reaffirmed that Brazil does not trade uranium for military purposes and is a signatory to nuclear non-proliferation treaties.
Uranium in Brazil is exclusively mined by the state-owned Nuclear Industries of Brazil (INB), and any international negotiation depends on approval from the Union.
Even with the 2022 legislation allowing the provision of services to foreigners, the monopoly on nuclear activity remains with the Brazilian State. All speculations regarding the shipment of uranium to Iran are false and baseless.
Investigations related to the visit of the Iranian ships, including possible links to the Revolutionary Guard, took place in 2023, with amendments included in the U.S. defense budget.
No new official developments have occurred since then, and no concrete evidence has been presented.
Iran, Israel, and the U.S. Pressured Brazil in 2023 During Geopolitical Tension in the Middle East
As early as March 2023, following the visit of the ships, Israel labeled the Brazilian decision as “regrettable” and called for alignment with Western countries. In a public statement, the Israeli regime asserted that the Iran is responsible for terrorist attacks worldwide and criticized Brazil for receiving military vessels from a “malign state.”
Behind the scenes, pressure intensified following the speeches from Senator Ted Cruz and Ambassador Elizabeth Bagley, which highlighted the risks of sanctions and the need to reassess counter-terrorism cooperation with Brazil.
The Brazilian government, in turn, upheld the principle of sovereignty in foreign relations and proceeded with the authorization, published in the Official Gazette of the Union.
Despite the diplomatic uproar, there were no breakages between the countries, but the episode was a milestone in the management of Brazilian foreign policy at the beginning of President Luiz Inácio Lula da Silva‘s third term.
CIA Document and Diplomatic Records Reinforce Suspicion About Hidden Objectives of the Visit
Telegrams sent by the Brazilian embassy in Washington and records from the Comptroller General of the Union reveal that CIA investigations have been ongoing since early 2023. Journalists from CNN en Español requested details about the docking, and public documents confirmed authorization for the disembarkation of the crews.
The hypothesis that members of the Iranian Revolutionary Guard may have been included in the Iranian diplomatic corps was not confirmed by any intelligence agency.
Nonetheless, the issue prompted an amendment by Congressman Carlos Jimenez demanding a report from the Department of Defense on the presence of Iranian military personnel in Brazil.
Based on this data, the U.S. Congress approved the request for an investigation back in 2023, but no concrete results were disclosed nor additional measures adopted.
Silence of the Brazilian Government and Fake News About Uranium Rekindle Discussions on Transparency
In 2025, the case resurfaced not due to new facts but because of the dissemination of disinformation. The narrative that the Iranian ship came to seek uranium in Brazil went viral on social media, based on old videos and out-of-context statements, such as the speech by Ted Cruz.
The Secom classified the publications as “false and alarmist”, emphasizing that Brazil strictly follows international treaties and that there is no indication of cooperation with the Iranian nuclear program.
The company INB also issued a statement reinforcing that it does not export enriched uranium and that all nuclear activity is monitored by national and international bodies.
Engraçado que falaram, falaram e falaram, mas não disseram que raios esses navios vieram fazer aqui!? Dar uma voltinha pelo Rio de Janeiro que não foi né?!
A pergunta é: Que raios vieram fazer aqui, então? O povo brasileiro quer transparência, isso é coisa séria.
1 – Por que cargas d’água dois navios militares viraram dar um rolê no Rio de Janeiro?
2 – Quem confia nas fontes de um desgoverno que é aliado ao Irã?
3 – Se o PT fala que é Fake, pode desconfiar que tem caroço neste angu.
