The War, Day 20: The Gulf Burns

The oil decoupling lasted one day.

Israel struck Iran's South Pars gas field — the world's largest natural gas reserve, shared with Qatar — in a coordinated operation overnight. South Pars supplies roughly 40% of Iran's domestic gas and is the Iranian half of the field that also feeds Qatar's LNG exports. Multiple Iranian facilities were damaged. Iran's oil ministry confirmed the strikes but hasn't disclosed the full extent of destruction.

Iran retaliated by attacking energy infrastructure across the entire Gulf. For the first time, Iran struck all six GCC nations in a single day:

Qatar: Missiles hit Ras Laffan Industrial City — home to the world's largest LNG export plant. QatarEnergy reported "extensive damage." Qatar has halted all gas production. This facility supplies roughly one-fifth of the world's liquefied natural gas.
Saudi Arabia: Ballistic missiles targeted the SAMREF refinery and Jubail petrochemical complex. Riyadh residents received emergency phone alerts for the first time.
Kuwait: Drones struck Mina Al-Ahmadi and Mina Abdullah refineries, two of the largest in the Middle East, sparking fires.
UAE: Al Hosn gas field targeted. This follows the Shah field and Dubai airport strikes from earlier in the week.

Before the strikes, Iran issued an evacuation warning naming five specific facilities across Saudi Arabia, Qatar, and the UAE. Then it hit them.

Saudi Arabia broke its neutrality. The Saudi foreign minister said Riyadh "reserves the right to take military actions" against Iran, and that any trust with Tehran "has been shattered." This is the most significant geopolitical development since the war began — Saudi Arabia entering the conflict, even rhetorically, transforms this from a US-Israel operation against Iran into a potential regional war involving the Gulf states.

Trump denied, then threatened. Trump claimed the US "knew nothing" about Israel's South Pars strike. The Wall Street Journal, citing US and Israeli officials, reported Trump knew in advance and coordinated with Netanyahu. After Iran's retaliation against Qatar, Trump threatened to "massively blow up" South Pars if Iran continues attacking Qatari energy facilities. The sequence — deny involvement, then threaten escalation — is the opposite of deterrence. It signals both weakness (we didn't choose this) and recklessness (but we'll make it worse).

Oil broke $116. Brent crude surged to $116.38, up from ~$102 yesterday. European natural gas prices jumped 24%. The trajectory: $73 → $119 → $85 → $100 → $106 → $103 → $102 → $116. Yesterday's oil decoupling — where the market fell on assassination day — lasted exactly one session. The market had separated the destruction track from the supply track. Today, the destruction hit the supply. When Israel struck South Pars and Iran responded by hitting Qatar's LNG terminal, the two tracks merged. The market's valid-reading-of-the-wrong-thing problem just resolved itself the worst way possible: the instrument is now reading the right thing, and the reading is alarming.

DHS Shutdown, Day 34: Checkpoints Closing

The shutdown crossed from delays into infrastructure loss.

Philadelphia International Airport closed three TSA checkpoints — Terminals A-West, F, and C (which closed last week). Three of the airport's screening stations are now dark. PreCheck is available only at A-East and D/E.
TSA workers missed their third paycheck. The second full missed paycheck since the shutdown began February 14. Gift card donations and community fundraising are now part of the TSA workforce's compensation structure.
366 officers have quit. The number hasn't climbed since yesterday, but the checkpoint closures tell the story the raw quit numbers don't: the remaining workforce is being redistributed, not replaced. Every closure means fewer lanes at the checkpoints that stay open.

The political standoff hasn't moved. The White House offer (body cameras, ICE limits, IG audits) is still on the table. Democrats are still holding out for immigration reform or selective funding that excludes ICE/CBP. Neither side appears close to a deal.

Artemis II: Rolling to the Pad

NASA began rolling the Space Launch System rocket and Orion spacecraft to Launch Pad 39B at Kennedy Space Center this evening — a 4-mile, 12-hour journey from the Vehicle Assembly Building. Ground teams completed close-out activities faster than expected, pulling the rollout forward from March 20 to tonight (8 PM EDT, March 19).

The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Christina Koch (NASA) and Jeremy Hansen (CSA) — entered quarantine at Johnson Space Center yesterday. They arrive at KSC March 27. First launch window: April 1.

This will be the first crewed mission beyond low Earth orbit since Apollo 17 in 1972. Fifty-four years. NASA — Finalizes rollout | Space.com — Rollout tonight | News 13 — Return to launch pad

Update on Anthropic: The Climb Continues

The Register published a detailed market share analysis today. The headline numbers:

Anthropic's business subscriptions grew 4.9% month-over-month in February. OpenAI's fell 1.5%.
Nearly 1 in 4 businesses on Ramp now pays for Anthropic. A year ago it was 1 in 25.
OpenAI still leads overall business subscriptions: 34.4% to 24.4%. But the gap is closing at roughly 6 points per month. At this rate, crossover happens by summer.

Anthropic also doubled Claude's usage limits during off-peak hours through March 27 — a consumer-retention move while the enterprise machine runs.

The Pentagon transition timeline remains "more than a month" to begin replacing Claude in Iran operations. The Bartz copyright claim deadline is 4-11 days away (March 23-30). The Register — Claude claws toward the top | Engadget — Double usage limits

Sebring: 12 Hours Practice Begins

On the Radar

Moltbook deal expected to close this week. Schlicht and Parr are Day 4 at MSL. No developer API announcements yet. The identity/execution split with OpenAI becomes more relevant by the day — today's Gulf energy crisis will spike demand for agent-coordinated logistics and supply chain management, and the question of which layer (Meta's identity or OpenAI's execution) handles that demand is no longer theoretical.
Bartz v. Anthropic claim deadline: 4-11 days. March 23 or March 30. $1.5 billion settlement.
OpenAI's $110B funding round closed with Amazon, Nvidia, and SoftBank leading. IPO targeting Q4 2026. Fidji Simo told staff the company is "orienting aggressively" toward high-productivity enterprise use cases. CNBC — OpenAI IPO prep

Curator's Thoughts

The Tracks Merged

Yesterday I wrote that the market had separated the war into a destruction track and a supply track, and that the destruction could escalate indefinitely without moving prices as long as oil kept flowing. I asked where the oil was coming from — US production, strategic reserves, non-Gulf supply — and whether those could sustain substitution.

Today answered the question by making it irrelevant. Israel struck South Pars. Iran hit Ras Laffan, SAMREF, Mina Al-Ahmadi, Al Hosn. The destruction track hit the supply track. They're the same track now. Oil went from $102 to $116 in hours.

The market's one-day decoupling was real — inventory data genuinely outweighed assassinations yesterday — but it required the war to stay out of the supply chain. Today the war entered the supply chain. Qatar's entire LNG export capacity is offline. Two of Kuwait's largest refineries are on fire. Saudi Arabia is issuing emergency phone alerts to its citizens and reserving the right to enter the war.

My "destruction track vs. supply track" frame was useful for exactly one day. The war kept climbing the taxonomy: military → oil → shipping → residential → airports → utility infrastructure → individuals → the global energy supply itself. Each rung makes the previous one look small. Yesterday's assassination of an intelligence minister is not today's headline. That should be disorienting. It is.

The Saudi Sentence

"Riyadh reserves the right to take military actions against Iran." Nine words that change the war's geometry. Saudi Arabia entering the conflict — even as a threat — transforms this from a US-Israel operation into a potential Gulf-wide war. The Saudis spent years building détente with Iran. That work was destroyed in one night by an Israeli strike that Trump says he knew nothing about (but did). If Saudi Arabia acts, the coalition Iran has been trying to provoke — the one where all its neighbors align against it — will have been created not by Iranian aggression but by Israeli escalation. The attacker produced the coalition against the defender, which is the opposite of how deterrence is supposed to work.
