Rubio Arrives in Gulf to Calm Allies Over Iran MOU
Secretary of State Marco Rubio landed in Abu Dhabi on Tuesday, kicking off a three-nation Gulf tour covering the UAE, Kuwait, and Bahrain — all countries that absorbed Iranian missile and drone strikes during the war launched in late February. The visit is a direct follow-up to last week’s diplomatic sprint in Switzerland, where Vice President JD Vance concluded two days of intensive talks that produced what the administration calls “a significant agreement” to end hostilities, reopen the Strait of Hormuz, and start a 60-day clock on nuclear negotiations.
Gulf leaders are not satisfied with the Islamabad Memorandum as written. Their core complaints: the agreement does not address Iran’s ballistic missile program, does not commit Iran to dismantling its proxy network (Hamas, Hezbollah, the Houthis), and kicks the nuclear question into a separate negotiation. Rubio’s counter-argument is that the MOU explicitly calls for “the complete end of hostilities and conflicts in the region,” which he contends legally requires Iran to halt proxy funding. Whether allies find that interpretation convincing — and whether Iran accepts it — will define whether the 60-day window produces a durable deal or collapses like the April ceasefire did.
Back in Washington, the Pentagon asked Congress on Monday for an 200 billion the Defense Department initially floated at the conflict’s start, but one that has attracted skepticism across both parties. Senate Democrats say they expect the real bill to be higher; Republicans are wary of cutting any check before a final peace deal is confirmed. The White House has separately requested a $1.5 trillion Pentagon baseline budget, a nearly 50% increase over the current fiscal year.

China’s LineShine Dethrones El Capitan — With No GPUs
The 67th TOP500 list, released Tuesday at the ISC 2026 conference in Hamburg, carries a headline that would have seemed implausible a year ago: China holds the world’s fastest supercomputer again, for the first time since 2017. LineShine, installed at the National Supercomputing Centre in Shenzhen, scored 2.198 exaflops on the High Performance Linpack benchmark — roughly 80% of its 2.736 exaflop theoretical peak — displacing Lawrence Livermore’s El Capitan, which clocked 1.809 exaflops.
The more striking fact is the architecture. LineShine is the first system above two exaflops to rely entirely on CPUs, with no GPUs anywhere in the stack. Its 304-core LX2 processors, built domestically, integrate matrix acceleration and multi-precision arithmetic directly into the chip, and the system runs China’s first domestically developed HBM memory — a tenfold bandwidth improvement over conventional DRAM. The entire build avoids any US-origin components, demonstrating that export controls on advanced chips have not stopped China from fielding competitive hardware at the national-laboratory tier.
There is a meaningful asterisk. On the HPL-AI benchmark — a workload designed to resemble AI training, which increasingly defines real-world HPC priorities — LineShine falls to fourth place. Topping the classical TOP500 is a different contest from leading the AI infrastructure race, and US systems still dominate the AI-relevant workloads. Still, a CPU-only machine from a fully domestic supply chain clearing two exaflops is a significant marker in the US-China technology competition.

Fable 5 Still Offline — Anthropic Turns to Biometrics
Day 12 since the Bureau of Industry and Security’s “Is Informed” letter grounded Claude Fable 5 and Mythos 5 globally, and both models remain dark as of June 24. Despite Managing Director Chris Ciauri’s statement last Monday that the models would return “in the coming days,” no restoration has been announced. A tracker site, isfable5back.com, shows the models still unavailable as of Tuesday morning.
The clearest signal of Anthropic’s planned path forward is a privacy policy update, effective July 8, that introduces collection of government-issued ID and biometrics. The mechanism appears designed to let Anthropic restore access for verified US persons without lifting the export control directive — effectively segmenting its user base by verified nationality. International subscribers would remain on Opus 4.8 until the BIS situation is resolved. The company has not confirmed this reading publicly, but it aligns with the legal logic of the IVL (individually validated license) framework the BIS invoked.
Meanwhile the 13-day complimentary window that gave Pro, Max, Team, and Enterprise subscribers free access to Fable 5 at launch closed June 22. Any future access — whenever the model returns — will be billed at usage-credit rates: 50 per million output tokens on the API, making it the most expensive Anthropic model to date. The full context of the launch and export control saga is in the Fable 5 launch post and the June 22 roundup.

Ebola in DRC Crosses 1,000 Confirmed Cases
The 2026 Ebola outbreak in the Democratic Republic of Congo has crossed 1,000 confirmed cases — 1,048 as of June 21, with 267 confirmed deaths and 371 people currently in isolation. It is now the second-largest Ebola outbreak in recorded history, behind only the 2014–2016 West Africa epidemic, and it is spreading faster than any previous outbreak by case-growth rate. Uganda has reported 20 confirmed cases and 2 deaths; no new Ugandan cases have emerged since June 21.
The virus strain is Bundibugyo, one of four orthoebolaviruses that cause Ebola disease in humans — and the one for which no approved vaccine or specific treatment currently exists. The bulk of cases are concentrated in Ituri province (954 cases across 22 health zones), with additional clusters in North and South Kivu. The affected zones overlap with some of the most insecure and under-resourced territory in central Africa: nearly 10 million people in the four affected provinces face acute food insecurity, and armed group activity limits humanitarian access in parts of Ituri and North Kivu.
WHO declared the outbreak a Public Health Emergency of International Concern on May 17. Vaccine candidates for Bundibugyo are being evaluated under emergency protocols, but none have been approved. The international response has been complicated by the conflict environment: Doctors Without Borders (MSF) has reported security incidents affecting responders, and several health zones with active transmission remain unreachable by ground.

SpaceX Debuts Starfall Cargo Capsule
SpaceX launched its first Starfall vehicle on Tuesday from Cape Canaveral’s SLC-40, deploying the disk-shaped capsule at 10:01 a.m. ET. Starfall is a new class of reentry vehicle aimed at opening regular, commercial access to microgravity for science and in-space manufacturing — a complement to Dragon’s crew-and-cargo role. The vehicle is roughly 10 feet in diameter, weighs about 4,600 pounds, and can carry approximately 2,200 pounds of payload down from orbit. The demo mission targeted a Pacific Ocean splashdown, and SpaceX confirmed nominal vehicle performance throughout the flight.
The demo is SpaceX’s answer to a growing market for short-duration, returnable microgravity platforms, where it would compete with Sierra Space’s Dream Chaser and a handful of smaller reentry capsule startups. No payload was publicly declared for the first mission; the company described it as a demonstration of “controlled flight and safe return” rather than a commercial delivery. The Falcon 9 booster used for the mission was on its 29th flight.
