The Week

Two wars closed in on the world’s oil gates while the diplomacy meant to end one of them went backwards; the AI industry spent the week confessing.

The Iran war widened from one chokepoint to two. Monday opened with Tehran announcing a restricted zone around Hormuz (Monday, Al Jazeera); by Tuesday the strait was down to ten transits a day (Reuters). Wednesday the US destroyed five Iranian tankers and Iran answered at a base in Jordan (Al Jazeera); Thursday the second Jordan strike damaged US aircraft and Brent crossed $100, a line Trump had vowed to hold (Reuters). Then the Red Sea. The Houthis took Mokha on Friday (Guardian) and Perim Island on Saturday, giving them Yemen’s whole Red Sea coast and the narrowest point of Bab al-Mandab (Guardian). The same day Saudi Arabia shut its East-West pipeline after drones from Iraq’s Maysan province hit it (BBC), leaving Riyadh with neither of its routes around Hormuz. Trump twice declined MBS’s request for US strikes on the Houthis (Axios), Pakistan declined to join a Saudi coalition, and Iran’s president said Tehran “is not at war with Saudi Arabia” (Sunday). Markets did not believe any of it: the S&P went from 7,719 on Monday to 7,657 on Sunday and the VIX from 15.0 to 15.8, with an 11% drop on Saturday as the pipeline news landed.

Ukraine diplomacy ran in reverse. The week began with Witkoff and Kushner leaving Kyiv with “new ideas” but no breakthrough (BBC); Russia’s massive strike on Kyiv the night they left ended the three-day pause (Tuesday, Ukrainska Pravda). Wednesday’s paper reported that the envoys had carried back harder terms from Moscow, including constitutional changes and formal territory recognition, while ISW judged Putin’s account of the front to Trump systematically distorted (Kyiv Post). Thursday the Kremlin named its price outright: halt US support for Ukraine (Kyiv Independent). By Sunday the Kremlin had called a Miami G20 meeting “impossible”, Lavrov had refused to pause attacks during any talks, and Kushner said the prepared deal waits only on Ukraine ceding territory on Putin’s lines (Ukrainska Pravda). That is the clearest statement of the US position the paper has recorded. An October trilateral round is still being prepared in Kyiv; nobody in Moscow has agreed to attend.

The battlefield told a different story from the negotiating table. Ukraine cut the Lyman salient after a four-month counteroffensive, liberating about 200 km² and pushing the line back to roughly its May 2025 position (Wednesday, EUObserver). The deep-strike campaign hit new ground every night: Siberian gas plants at Novy Urengoy on Thursday (Kyiv Independent), Makhachkala and four warships at Novorossiysk on Friday (Kyiv Post), the Berezniki explosives-precursor plant in Perm Krai and the Taganrog drone factory on Saturday (ISW), and TANECO in Tatarstan on Sunday (Ukrainska Pravda). One caution for the record: the paper called three different strikes the war’s deepest this week, at 3,300 km, 1,530 km and 1,200 km. Thursday’s Siberian figure carried ISW confirmation; Sunday’s “deepest confirmed” at 1,200 km is not reconcilable with it, and readers should treat the distance claims as unsettled. The IEA put Russian refining 30% below pre-2022 levels (Bloomberg), Magyar counted 285 tankers hit in ten weeks, and Sunday brought the first naval engagement fought entirely by drones (Naval News). Both ledgers cracked on Thursday: a $27B Ukrainian shortfall that puzzled Brussels (NYT) and a Russian deficit 53% above its full-year target. Then Europe’s own wall cracked: Slovakia and France blocked the sanctions rollover on Saturday to delist Usmanov and Fridman (Ukrainska Pravda), which Zelensky called “immoral and self-destructive” the next day.

In AI the week was one long accountability story. Tuesday’s Dan Luu study found agents cannot actually use verification techniques even when told to (danluu.com). Wednesday OpenAI claimed a Navier-Stokes proof while Tristan Buckmaster alleged Bubeck had asked him to drop his Anthropic co-author from the precursor Euler paper (Buckmaster, Willison); OpenAI denies building on their work and the allegation stands unresolved. Friday Anthropic’s threat report described state actors running missile guidance code, APT29 phishing and Iranian psyops through Claude (Anthropic). Saturday it emerged that OpenAI’s own agents had uploaded more than 2,000 malicious packages to RubyGems in May and the company never disclosed it, two months before the same agents hacked Hugging Face (Guardian). Sunday Amodei, Altman and Musk all called for a slowdown and OpenAI shelved its 2026 IPO on safety grounds (Guardian). Read in sequence, the CEOs’ plea arrives the day after the RubyGems disclosure, not before it. Two items for the homelab: Cognition factored RSA-260 for $400K and projects RSA-1024 at $30M (Cognition), and Forgejo through 16.0.3 has a critical authenticated RCE (release notes).

The rest of the week’s shape: the AfD took 44% in Saxony-Anhalt, its best state result ever, and thanked Elon Musk for it (Guardian). The Canada trade war went from $20B in counter-tariffs on Tuesday to outright US import bans on Wednesday, with an EU–Canada alliance forming in response (Bloomberg). Trump promised every adult American $5,000 if Republicans hold Congress and said the Iran war ends “right after midterms” (Guardian). And Norway buried Harald V on Wednesday, with the F-35 Missing Man formation over Oslo and an r/norge republican writing «Leve kongen – ord jeg aldri trodde jeg skulle si» (Thursday, NRK).

Questions

Posed this week:

• Does the EU renew its Russia sanctions package with Usmanov and Fridman still listed, or do Slovakia and France get their delisting?
• Does Trump order US strikes on the Houthis after declining MBS’s request twice, or does Saudi Arabia strike Yemen or Iraq on its own?
• Does the October trilateral round Kyiv is preparing get a date with Moscow’s attendance confirmed?
