Opinion | Iran Is Teaching Us Something About the American War Machine

“This is the time where danger lights should be flashing for a great power like the United States, if we take history as a guide," PWH Faculty Director @mchorowitz.bsky.social explains in a @nytimes.com piece by @dwallacewells.bsky.social. Read here: www.nytimes.com/2026/04/15/o...

A ‘Fight About Vibes’ Drove the Pentagon’s Breakup with Anthropic The AI giant’s CEO Dario Amodei and Defense Secretary Pete Hegseth have contrasting personalities and worldviews.

“This is a fight about vibes and personalities masquerading as a policy dispute,” explains PWH Faculty Director @mchorowitz.bsky.social in a quote for this @wsj.com piece on the Pentagon's split from the AI company Anthropic. Read here: www.wsj.com/tech/ai/anth...

The hypothetical nuclear attack that escalated the Pentagon’s showdown with Anthropic Start-up Anthropic and the U.S. military are careening toward a clash over government use of artificial intelligence — and whether it should be allowed to kill.

PWH Faculty Director @mchorowitz.bsky.social is quoted in this @washingtonpost.com piece on the fight between Anthropic & the Pentagon: “The Pentagon does not trust that Anthropic will be a reliable vendor, and Anthropic worries about misuse of its technology." www.washingtonpost.com/technology/2...
