A Revolução Cubana sempre teve um espírito internacionalista

(Jacobin Brasil / 2026-02-27 16:56)

Resumo objetivo:
Um evento em Havana relembrou o 60º aniversário da Conferência Tricontinental de 1966, realizada originalmente como um marco de solidariedade anticolonial e anti-imperialista entre países do "Terceiro Mundo". A conferência, que incluiu a América Latina e atraiu principalmente movimentos de oposição, representou uma radicalização do discurso contra o imperialismo estadunidense, distanciando-se da abordagem soviética mais cautelosa. Seu legado é avaliado mais pelo simbolismo e pela consciência de solidariedade que gerou do que por resultados organizacionais tangíveis.

Principais tópicos abordados: 1. Contexto histórico e significado da Conferência Tricontinental de 1966. 2. Divergências entre Cuba, União Soviética e China durante a Guerra Fria. 3. O foco anticolonial, anti-imperialista e a inclusão da América Latina. 4. O legado simbólico do evento para movimentos radicais globais.

Cities Hosting Major Events Need More Focus on Wireless, Drone Defense

(darkreading / 2026-02-27 20:23)

Cybersecurity experts warn that cities hosting major events like the 2026 FIFA World Cup must enhance defenses against evolving wireless and drone threats. These threats include the potential disruption of operational technology, such as stadium systems and public safety communications, through jamming or hijacking of wireless signals. The dense radio-frequency environment during such events creates vulnerabilities for wireless surveillance and infrastructure attacks. A key challenge is the lack of visibility and authority for local law enforcement to effectively counter these drone and wireless-based risks.

Trump Moves to Ban Anthropic From the US Government

(Business Latest / 2026-02-27 21:36)

President Donald Trump has ordered all federal agencies to immediately cease using Anthropic's AI tools, initiating a six-month phase-out period. This follows a dispute between the AI company and the Pentagon over military applications, with Anthropic objecting to the removal of contractual restrictions that could allow AI to control lethal autonomous weapons or conduct mass surveillance.

Defense Secretary Pete Hegseth designated Anthropic a "supply chain risk," barring the U.S. military and its contractors from working with the company, and criticized its leadership for refusing the Pentagon's demand for "all lawful use" of its technology. The conflict tests the limits of Silicon Valley's shift toward defense work, with other AI companies and hundreds of tech workers expressing support for Anthropic's ethical stance.

Main Topics: U.S. government ban on Anthropic AI, military-corporate dispute over AI ethics and use restrictions, supply chain risk designation, Silicon Valley's evolving relationship with defense contracting.

Anthropic Hits Back After US Military Labels It a ‘Supply Chain Risk’

(Business Latest / 2026-02-28 03:30)

The U.S. Department of Defense designated AI company Anthropic as a "supply-chain risk," effectively barring military contractors and partners from doing business with it. This followed a breakdown in negotiations, where Anthropic refused to allow unrestricted "all lawful uses" of its AI by the military, seeking prohibitions on mass surveillance and autonomous weapons.

The designation has caused significant alarm in Silicon Valley, with critics calling it an overreach that damages a leading American AI firm. Anthropic is challenging the move in court, arguing the Defense Secretary lacks the authority for such a broad ban and that the designation sets a dangerous precedent.

Meanwhile, OpenAI announced a separate agreement with the Pentagon to deploy its AI in classified environments, explicitly incorporating safety principles similar to those Anthropic sought. The practical impact on Anthropic's existing customers remains legally unclear and contested.

Main Topics: U.S. Defense Department's supply-chain risk designation of Anthropic; the contractual dispute over AI use limits; industry and expert reaction; legal challenges and precedent; contrasting deal with OpenAI.

The U.S. government has designated AI company Anthropic as a national security supply chain risk and ordered federal agencies and military partners to phase out its technology. This follows a breakdown in negotiations, as Anthropic refused to allow its AI model, Claude, to be used for mass domestic surveillance or fully autonomous weapons. Anthropic argues these uses are unethical and legally unsound, while the Pentagon insists it needs the ability to use AI for all lawful military purposes without restrictions. The dispute has divided the tech industry, with some employees supporting Anthropic and others siding with the government.
