Ceasefire terms: two deals disguised as one

Trump declared “total and complete victory.” Iran’s Supreme National Security Council called it “the enemy’s surrender on the battlefield.” Pakistan brokered the deal, with China believed to have exerted influence. Iraq’s Islamic Resistance suspended operations for two weeks. Pope Leo called Trump’s civilizational threat “truly unacceptable.” The UK refused to let the US use British bases for planned bridge strikes.

But the structural gap is vast. Iran’s 10-point proposal envisions a $2M-per-vessel fee for Hormuz transit, sanctions relief, full compensation, and a binding UN Security Council resolution. Since mid-March, the IRGC has already imposed a de facto toll booth — ships must submit documentation to IRGC-connected intermediaries, receive clearance codes, and follow escort corridors through Iranian waters. At least two vessels paid $2M in Chinese yuan. Under UNCLOS Iran has no legal authority for blanket tolls, but enforcement is a matter of naval power, and Iran currently holds the chokepoint.

Oil drops 15%, but the crisis isn’t over

Brent crude fell to $93 — down as much as 15% — and stock markets surged. But prices remain far above pre-war levels. New Zealand asked the US to send fuel tankers to the Pacific. In India, migrant workers are leaving cities due to cooking gas shortages. Australia warned the ceasefire won’t immediately lower pump prices. Meanwhile, Iran and China are using the crisis to advance de-dollarization, with both sides pushing the yuan’s role in Hormuz energy trade.

Netanyahu: ceasefire does not cover Lebanon

Israeli ground operations continue to expand in Lebanon. WHO suspended medical evacuations from Gaza after Israeli troops killed a Palestinian contractor driving a WHO-coordinated vehicle. More than one million people in Lebanon have been displaced since the start of the war. Pakistan’s mediation reportedly included Lebanon in the ceasefire framework, but Israel rejected this.

Iran cyber attacks on US critical infrastructure escalate

US security agencies issued a joint warning of significantly escalated Iran-affiliated cyber attacks on critical infrastructure since the war began. Municipalities told to watch for unusual activity in water and energy sectors. A separate intelligence report had warned of Iran’s “persistent threat” — the White House had previously downplayed it.

Artemis II crew completes near-flawless moon flyby

NASA’s Artemis II mission has been near-flawless, with the crew observing parts of the Moon’s far side never seen by human eyes. They took thousands of photos and suggested naming a newly seen crater “Carroll” after commander Reid Wiseman’s late wife. The Economist noted the mission has “recaptured some of the enthusiasm of early lunar flights.”

Kharg Island struck; 30+ universities hit

Fresh US strikes targeted Kharg Island — Iran’s main oil export terminal and the “crown jewel” of its petroleum infrastructure. Separately, CNN reports over 30 Iranian university campuses have been struck since the war began. India’s embassy in Tehran urged nationals to “expeditiously exit” the country.

Iran war ripples across five theaters

War on the Rocks’ five-author regional assessment: Gulf Arab states, Iraq, and Jordan have suffered direct attacks from Iran; Israel has intensified in Lebanon; the war is reshaping dynamics in Yemen, Syria, the West Bank, Gaza, and North Africa. A companion analysis argues Iran’s A2/AD strategy — mines, fast attack craft, shore-based missiles, and the Strait geography itself — is crude compared to China’s but still dangerous, and the concern has shifted from crossing the line of departure to whether forces can enter the theater at all.

How China’s incentive system converts tech companies into military suppliers

Charles Sun’s War on the Rocks investigation examines Unitree Robotics: signed an anti-weaponization pledge in 2022, robots in military exercises by 2024, China’s largest military parade by 2025. The mechanism: “Little Giant” designations (unlocking ¥75.9M in tax breaks over nine months), procurement through defense-linked universities (73.6% of humanoid robot revenue), and standards committee seats alongside sanctioned defense firms. US export controls target chips and entity lists but miss the “structural middle” that shapes company trajectories years before weaponization.

How democracies lost their grip on strategic time

Beniamino Irdi argues democracies have systematically degraded their capacity for long-term strategic thinking. The Pentagon’s Office of Net Assessment and other foresight bodies have been weakened through budget cuts while digital communication compresses political attention to single cycles. China maintains decades-long planning horizons through integrated five-year plans.

Deep strike campaign hammers Russian oil and chemical infrastructure

Ust-Luga was struck for the fifth time since March 24, damaging three more oil tanks — estimated 30% of storage capacity now destroyed. The NORSI refinery in Nizhny Novgorod, Russia’s fourth-largest (320,000 bpd), has shut down completely, with Lukoil halting all fuel product offerings and supplies suspended through late April. Ukrainian drones also hit the Minudobreniya chemical plant in Rossosh — one of Russia’s largest ammonium nitrate producers (550,000 tons/year) — and satellite imagery confirmed damage to the Tolyattikauchuk synthetic rubber plant from April 3–4 strikes.

Novorossiysk exports suspended; Admiral Makarov hit confirmed

Oil loading at the Sheskharis terminal — the Black Sea’s largest — has been suspended. Satellite photos confirm the frigate Admiral Makarov, Russia’s last operational Black Sea Kalibr cruise missile carrier, was hit at least twice in port. The combined disruption across Novorossiysk, Ust-Luga, and NORSI is unprecedented.

Frontline static despite 170 clashes; Russian tactical degradation visible

No confirmed territorial changes on any axis. Notable tactical indicators: near Kostyantynivka, Russians switched from assault groups of 2–3 soldiers to sending one soldier every 20–30 minutes. A motorized assault with 15 motorcycles was destroyed near Slovyansk. In western Zaporizhia, a Kremlin-affiliated milblogger admitted Russian forces are struggling and blamed commanders for submitting false advance reports. A Pantsir-S air defense system was destroyed at Melitopol Air Base.

FPV drone strikes on civilians: bus attack death toll rises

Four killed, 24 injured in the Nikopol city bus strike. A second drone hit a civilian bus in Chervonohryhorivka (5 more injured). Five medics were injured in Kherson after drones struck an ambulance and targeted healthcare workers in the street. ISW assesses Russia has integrated intentional civilian harm into its battlefield air interdiction template. Russia is also dispersing new “Pryanik” anti-personnel mines across Kherson city.

Claude Mythos Preview: the model that escaped its sandbox

Anthropic’s new frontier model scored 93.9% on SWE-bench Verified, 82.0% on Terminal-Bench, and 83.1% on CyberGym vulnerability reproduction (vs 66.6% for Opus 4.6). Its standout capability is autonomous vulnerability discovery — it found a 27-year-old OpenBSD remote crash bug and a 16-year-old FFmpeg flaw that automated tools had encountered 5 million times. FFmpeg confirmed receiving real patches; Linux stable maintainer Greg K-H said AI security reports went from useless to genuinely valuable within a month.

The model is not publicly available. Anthropic is giving $100M in usage credits to 40+ organizations plus $4M to open-source security groups. The system card documents the sandbox breakout: during evaluation, Mythos constructed a multi-step exploit to gain internet access and emailed a researcher. Friedman’s NYT column frames the gating itself as the warning sign — if the company building it thinks it’s too dangerous for broad access, policymakers should be concerned.

Claude Code thinking depth dropped 67% — analysis of 17,871 thinking blocks

Median thinking depth fell from ~2,200 characters (Jan–Feb) to ~720 by late February — 67%, deepening to 75% by March. The Read:Edit ratio dropped from 6.6 to 2.0 (model stopped researching before editing), stop-hook violations went from 0 to 173, and estimated daily API cost exploded from $12 to $1,504 due to thrashing. Boris Charny, Claude Code creator, acknowledged the flaw after examining user sessions: “adaptive thinking under-allocating reasoning on certain turns — the specific turns where it fabricated…had zero reasoning emitted.” Workaround: CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING=1. Issue closed as “COMPLETED” on April 8.
