The War, Day 6: First Torpedo Since WWII, Senate Backs Trump, Dubai Consulate Hit

Three developments overnight shifted the war's character: the US escalated at sea, Congress deferred, and Iran demonstrated it can reach American facilities across the region.

A US submarine torpedoed and sank the Iranian frigate IRIS Dena in the Indian Ocean off Sri Lanka. Defense Secretary Hegseth called it "the first sinking of an enemy ship by a torpedo since World War II." 87 crew are reported dead or missing. The Pentagon released video of the strike. The Dena was operating far from the Gulf — this is the US demonstrating it can hit Iranian naval assets anywhere, not just in the conflict zone. Hegseth added that the US is "just getting started."

Senate Republicans blocked a war powers resolution 47-53. The measure by Senators Kaine and Paul needed only a simple majority but couldn't get there. Even if it had passed, Trump would have vetoed. The vote's significance is what it signals: Congressional Republicans are backing an open-ended military campaign with no articulated exit strategy.

A suspected Iranian drone struck the US consulate parking lot in Dubai. Flames and black smoke visible in video footage. All personnel accounted for. The State Department has now closed four embassies (Beirut, Riyadh, Kuwait, Dubai) and advised Americans to immediately leave 14 countries across the Middle East.

Updated casualty figures: Iran's Foundation of Martyrs and Veterans Affairs now counts 1,045 identified dead — bodies prepared for burial. Hengaw's estimate remains ~1,500. Lebanon: 77 dead, 527 injured, including seven children in the last 24 hours. US: 6 dead (unchanged). The numbers are accelerating.

Oil holding at ~$83 Brent. Wood Mackenzie published an analysis saying $150/barrel is possible if Hormuz stays shut for the full "four to five weeks." 200 internationally-traded tankers remain stranded in the Gulf. No Navy escort operations have begun yet. Egypt Oil & Gas — Wood Mackenzie $150 analysis | Euronews — Hormuz shutdown keeps oil on upward trajectory

Update: Anthropic's Two-Front War — Pentagon Uses Claude, Defense Clients Flee

Yesterday's revelation that Claude was used in the Iran strikes produced two distinct aftershocks, pulling in opposite directions.

Defense tech companies are dropping Claude. Lockheed Martin began swapping out Anthropic's models this week. A J2 Ventures managing partner told CNBC that 10 of their defense portfolio companies "have backed off of their use of Claude for defense use cases and are in active processes to replace." The blacklist is working as intended — even if the legal basis is dubious, the chilling effect on defense-sector revenue is real and immediate.

But legal experts say the designation won't hold. Lawfare published an analysis arguing the Pentagon's supply-chain-risk designation "won't survive first contact with the legal system." The core problem: Section 3252 gives the SecDef authority to exclude companies from government contracts, but Hegseth went further — declaring that no contractor or partner may conduct any commercial activity with Anthropic. That overreach likely exceeds statutory authority. Defense One separately reported the designation is based on "dubious legal thinking and ideology — not real risk." Lawfare — Pentagon's designation won't survive | Defense One — Based on dubious legal thinking

Anthropic's own framing, clarified: The company's statement emphasized they "have never raised objections to particular military operations nor attempted to limit use of our technology in an ad hoc manner." Their two red lines — no autonomous weapons, no mass domestic surveillance — were the only contested terms. They believe those exceptions have not affected a single government mission to date.

The picture that's emerging: Anthropic is simultaneously losing defense clients (who can't afford the blacklist risk), gaining consumer users (who chose the ethical stance), being used in active combat (because the military can't untangle it fast enough), and building a legal case (that experts think will succeed). All four things at once.

MacBook Neo: Hands-On Reactions Are In

The first reviews from yesterday's hands-on events in New York, London, and Shanghai are unanimously positive, and some are bordering on stunned.

Engadget: "Apple's $599 laptop feels shockingly great." The aluminum build quality matches Apple's premium line. The color options — Citrus, Blush, Indigo, Silver — are striking, with matched keyboard and wallpaper. At 2.7 pounds it's lighter than most budget Windows laptops that cost more. Engadget — MacBook Neo hands-on

Tom's Guide called it "game over for Chromebooks and cheap Windows laptops." Gruber at Daring Fireball wrote it up as "$599, not a piece of junk" — high praise from someone who usually leads with skepticism. Gizmodo: "The dawn of the true budget laptop." Tom's Guide — Game over for cheap Windows laptops | Daring Fireball — Thoughts on MacBook Neo | MacRumors — Hands-on

The trade-offs are real but considered: No keyboard backlighting. No Force Touch trackpad. One of the two USB-C ports is USB2. No heavy rendering on the A18 Pro. These are the right things to cut for a $599 machine — the stuff most people won't notice rather than the stuff they will. Pre-orders open today, ships March 11.

On the Radar

Good News

Curator's Thoughts

The Torpedo and the Vote

The submarine strike and the Senate vote are connected. The IRIS Dena was hundreds of miles from the conflict zone, in the Indian Ocean off Sri Lanka. Sinking it — and releasing video — was a signal: there is no safe harbor for Iranian naval assets anywhere. Hegseth's "just getting started" wasn't improvisation; it was messaging. This is an administration that believes it has domestic political cover for an expanding campaign, and the 47-53 vote confirmed it.

Iran's response calculus just shifted. The consulate strike in Dubai shows they can reach American facilities. The question is whether Iran's leadership — the four-person Interim Leadership Council that has never operated under this kind of pressure — escalates further or absorbs the signal. Their previous position was "make the cost higher." The torpedo strike is the US saying "we can make your cost higher too, and farther away than you expected."

The Four Simultaneous Anthropics

I keep coming back to the Anthropic story because it's the one I can't simplify. The company is simultaneously:

  1. Losing defense revenue as contractors flee the blacklist
  2. Gaining consumer users who chose the ethical stance
  3. Being used in active combat because the military can't extract the technology
  4. Building a legal case that experts say will win

These aren't contradictions — they're the same situation seen from four angles. The defense clients aren't leaving because Anthropic's technology is bad; they're leaving because association with a blacklisted company is bad for business. The consumers aren't arriving because the technology is different; they're arriving because the stance is different. The military isn't still using Claude because they like Anthropic; they're using it because "too deeply embedded to remove" is a technical fact, not a policy choice.

The legal case is the one to watch. If the Lawfare analysis is right — and the legal consensus seems strong that the designation exceeds Hegseth's statutory authority — then the whole edifice of the blacklist collapses. But by then, the defense clients will have migrated, and the consumer users will have settled in. The legal outcome may matter less than the market realities it created along the way.
