• “It is incredible how far the overton window has moved on this issue. When I graduated in 2007, it was common for tech companies to refuse to let their systems be used for war, and it was an ordinary thing when some of my graduating classmates refused to work at companies that…” — Hacker News (630 pts thread)

  Our take: We think that read is basically right: Anthropic is not taking a classic anti-war stance here. It is saying yes to national-security deployment, but no to two categories it believes are technically and morally too dangerous.

• “Raised an eyebrow a little at this sentence: "Anthropic has much more in common with the Department of War than we have differences."” — Hacker News (630 pts thread)

  Our take: That line really does jump off the page. It is Anthropic trying to establish patriotic credibility while simultaneously telling the Pentagon, in court-adjacent language, that some uses are still off limits.

• “> Our most important priority right now is making sure that our warfighters and national security experts are not deprived of important tools in the middle of major combat operations. > we had been having productive conversations with the Department of War over the last several…” — Hacker News (630 pts thread)

  Our take: The question has bite, because Anthropic’s pitch to talent has always included a stronger safety identity than its peers. But leaving OpenAI for Anthropic was never a promise of zero military work; it was a bet that this company would draw sharper lines when the pressure came.

# Statement from Dario Amodei on our discussions with the Department of War

Feb 26, 2026

I believe deeply in the existential importance of using AI to defend the United States and other democracies, and to defeat our autocratic adversaries.

Anthropic has therefore worked proactively to deploy our models to the…

• “This is the strongest statement in the post: > They have threatened to remove us from their systems if we maintain these safeguards; they have also threatened to designate us a “supply chain risk”—a label reserved for US adversaries, never before applied to an American…” — Hacker News (2920 pts thread)

  Our take: We agree that this contradiction is the center of Anthropic’s best argument: the government is calling Claude dangerous enough to blacklist and important enough to compel. The Pentagon’s answer is probably that it wants the tool without the vendor’s restrictions, but rhetorically, Anthropic has found the weak seam.

• “I was reading halfway thru and one line struck a nerve with me: > But today, frontier AI systems are simply not reliable enough to power fully autonomous weapons. So not today, but the door is open for this after AI systems have gathered enough "training data"? Then I re-read…” — Hacker News (2920 pts thread)

  Our take: This is a fair push. Anthropic’s red lines are narrow by design, and listeners should not confuse “safety-forward” with “anti-war” or even with a broad civil-liberties position on every possible surveillance use.

• “I used to work at Anthropic, and I wrote a comment on a thread earlier this week about the RSP update [1]. It's enheartening to see that leaders at Anthropic are willing to risk losing their seat at the table to be guided by values. Something I don't think is well understood on…” — Hacker News (2920 pts thread)

  Our take: We buy that values inside Anthropic can be sincere and still contested from the outside. The hard part is that sincerity does not settle where the line belongs once the company is already deeply embedded in national-security systems.
