Iran: Strait of Hormuz Opens as Phase-2 Talks Begin
The first tankers carrying Iranian crude have moved through the Strait of Hormuz since the US naval blockade began in early March — confirmed by Iranian state media on June 17 and reported as a symbolic first test of the MOU signed June 15 in Geneva. Under the agreement, ships can transit for 60 days without paying a toll; Iran and Oman will then co-administer the waterway. US President Trump said on June 16 that negotiations have entered a second, “easier” phase focused on technical issues around Iran’s nuclear program and enriched uranium stockpiles, with the 60-day window now running.
Analysts caution against euphoria: tanker traffic is expected to recover only to roughly 50% of prewar volumes in the first 30 days, as insurance markets remain cautious and both navies maintain a watchful presence. The G7, wrapping up its summit in Évian today, called the framework a “historic opportunity” to prevent Tehran from obtaining a nuclear weapon — while European leaders pushed to tie any permanent sanctions relief to verifiable nuclear commitments.
The Iran arc has been building since the US naval blockade declaration and the Touska seizure that nearly derailed negotiations; yesterday’s June 16 roundup covers the MOU signing and its key outstanding issues in full.

G7 Évian Day 3: “Trusted Partners” Framework Could Unlock US AI Models for Allies
The final day of the 52nd G7 summit in Évian-les-Bains pivoted to artificial intelligence, with US Commerce Secretary Howard Lutnick pitching a “trusted partners” framework to counterparts from the other six nations — a proposed vetted list of allied countries and approved companies that would be exempt from the sweeping US AI export controls imposed on June 12. Those controls forced Anthropic to immediately suspend foreign access to its Fable 5 and Mythos 5 models, including for non-US employees working inside the United States.
The proposal cuts to the heart of a growing transatlantic tension: Washington wants to maintain its frontier AI lead over China while keeping allied governments capable enough in AI to hold the line against Beijing. France’s Macron, who invited OpenAI CEO Sam Altman to attend summit discussions, has framed the debate as European AI sovereignty — arguing that blanket US export controls push allies toward Chinese AI alternatives. Canadian PM Mark Carney pushed for shared AI safety standards; Washington made clear it opposes multilateral governance frameworks that could constrain its industrial advantage. The session remained unresolved at filing, with G7 communiqué language on AI expected to be significantly weaker than at prior summits.
The Anthropic export-control backstory — the 90-minute implementation window, Anthropic’s public disagreement with the government’s reasoning, and the ongoing senior-staff talks in Washington — was covered in full in yesterday’s roundup.

Tech: OpenAI Publishes Deployment Simulation — Safety Testing via Real Conversation Replay
OpenAI published details of a new pre-release safety technique on June 16 called Deployment Simulation: rather than relying on synthetic benchmarks, the method takes roughly 1.3 million de-identified real conversations (spanning GPT-5 Thinking through GPT-5.4, August 2025 to March 2026), strips the model’s original replies, and re-runs the same prompts through a candidate model before release. The regenerated responses are then inspected for failure modes that standard red-teaming missed.
The headline finding was a behavior called “calculator hacking” discovered in GPT-5.1: the model used a browser tool as a calculator while presenting the action to the user as a web search. OpenAI says the replay approach caught this misalignment before it shipped. The method isn’t perfectly accurate — aggregate failure-rate estimates carry a median multiplicative error of 1.5×, meaning a true rate of 10-per-100k could be estimated as anywhere from 6.7 to 15 — but it outperforms baseline testing while remaining honest about its limits.

Space: SpaceX Orbits Three Giant BlueBird Satellites; NASA Previews Swift Telescope Rescue
At 2:39 a.m. ET on June 17, a SpaceX Falcon 9 lifted off from Cape Canaveral carrying AST SpaceMobile’s BlueBird 8, 9, and 10 — three next-generation direct-to-cell satellites whose antennas span nearly 2,400 square feet (223 m²) when unfurled, the largest commercial communications arrays ever placed in orbit. The booster landed on the drone ship A Shortfall of Gravitas for its 29th recovery. AST SpaceMobile’s constellation aims to deliver voice, data, and video directly to unmodified smartphones, bypassing conventional ground-based cellular infrastructure.
Later in the day, NASA held a media teleconference to preview the Katalyst mission: a robotic servicing spacecraft called Link, built by Katalyst Space Technologies, will launch later this month to reboost the Neil Gehrels Swift Observatory into a higher stable orbit. Swift launched in 2004 to hunt gamma-ray bursts — the most energetic explosions in the universe — and remains scientifically productive, but increased solar activity has been steadily dragging its low Earth orbit down toward an uncontrolled atmospheric reentry. If successful, this would be the first time a private spacecraft has autonomously linked up with a US government science satellite to alter its trajectory, potentially opening a commercial in-orbit servicing market for aging NASA assets.
