Iran: Diplomacy Restarts as Netanyahu Flies to Washington#

President Trump said Monday there is “a good chance” the latest round of Iran diplomacy could produce a breakthrough — while simultaneously warning he would quickly resume airstrikes if talks collapse. Netanyahu departed Israel under unusual secrecy amid reported Iranian security threats and landed in Washington for the first face-to-face meeting with Trump since the two launched their joint war against Iran in late February. The two leaders are expected to compare notes on the pause in U.S. strikes and on how far Washington is willing to go in making concessions to Tehran. Reports suggest their relationship has grown strained over diverging timelines: Netanyahu has pushed to keep military pressure on, while Trump’s team is eyeing the November midterms as a deadline for a visible diplomatic win.

Iran’s foreign ministry spokesman Esmail Baghaei flatly denied that U.S. strikes had compelled Iran to request new talks and gave no indication that Tehran was ready to make concessions or meet directly with American officials. The more substantive diplomatic channel remains Oman: Iranian and Omani deputy foreign ministers met over the weekend in Tehran, reaching what both sides described as “some progress.” Oman proposed a regional maritime security consortium to govern Hormuz transit — toll-free in principle, with a voluntary environmental service fee — but Iran is insisting on retaining unilateral control and collecting its own transit fees. The gap remains wide, though the channel is active.

Separately, 28 vessels transited Bab el-Mandeb on Monday, the highest four-day total since Houthi operations intensified. Hormuz traffic remains sharply depressed. Earlier context: the Hormuz blockade background and the Houthi entry into the conflict.

Ukraine: Trump Shifts From Pessimism to Optimism on Zelenskyy#

A notable private reversal has emerged in how Trump is reading the Ukraine war. According to the Wall Street Journal, Trump has moved away from his earlier position — shared quietly with advisers — that Ukraine was losing, and is now expressing genuine optimism about Zelenskyy’s resilience and Ukraine’s battlefield trajectory. The shift follows recent Ukrainian strikes deeper into Russian territory. Advisers say Trump has been impressed by Zelenskyy personally and by the fact that Ukraine keeps pushing forward rather than collapsing.

The change in tone matters because U.S. diplomatic posture on Ukraine peace terms tends to follow Trump’s instincts. A Trump who believed Ukraine was losing would press Kyiv to negotiate from weakness; a Trump who sees Ukraine as holding — or gaining — is more likely to allow Kyiv leverage in any eventual talks with Moscow. The July 23 Rubio-Lavrov meeting in Manila opened a channel, but produced no public commitments from either side.

China Masters the Lithography Gap: Domestic DUV Machines Enter Mass Production#

China has begun mass-producing home-grown immersion deep-ultraviolet (DUV) lithography machines — the specialized tools needed to manufacture advanced semiconductors — in what analysts are calling the most significant breakthrough yet in Beijing’s drive to build a sovereign chip supply chain. The machines are being produced by Shanghai Aishengna Electronic Technology Group, a state-backed firm assembled from teams at several Chinese lithography startups. Roughly five units are expected to ship in 2026, rising to around twenty in 2027, with SMIC, Hua Hong Semiconductor, and ChangXin Memory Technologies (CXMT) as the first recipients.

The strategic context is hard to overstate. Since the U.S. imposed export controls on advanced chips and persuaded the Netherlands to restrict ASML from selling its EUV lithography tools to China, immersion DUV has become China’s only realistic path to manufacturing competitive chips at scale. Producing these machines domestically breaks a critical choke point — the theory behind U.S. chip controls was that denying tools would delay Chinese semiconductor progress by years. The caveat is real: CNBC reports that some components still come from Japan, and supplier delays have constrained 2026 output. But the direction of travel is clear: China is closing the gap faster than most Western analysts expected.

Amodei Clarifies: No Open-Weight AI Ban, But Squeeze China’s Chip Access#

Anthropic CEO Dario Amodei published a statement on July 27 asserting that “Anthropic has never advocated for a ban on open-weight models” — a direct response to mounting speculation that the company had quietly backed such a move amid U.S.-China AI tensions. The clarification came in the wake of Kimi K3, the Chinese open-weight model from Moonshot AI whose debut rattled Silicon Valley by approaching frontier performance at a fraction of the cost. (The White House last week separately accused Moonshot of covertly distilling Anthropic’s Fable model to train Kimi K3 — see last week’s roundup for that story.)

Amodei’s actual policy asks are narrower and more targeted: stop industrial-scale distillation of proprietary U.S. models, tighten chip export controls to cut off China’s access to training-grade compute, and require mandatory safety evaluations for any model above a capability threshold — regardless of country of origin. He argued that open-weight models without dangerous capabilities represent “a public good” and that banning Chinese open-source AI would be largely ineffective since “bad actors are unlikely to be legitimate U.S. businesses.” Where he drew a harder line was on models capable of providing meaningful assistance in developing bioweapons, which he framed as a genuinely asymmetric risk requiring stricter controls.

US Walks Out of UN Security Council After France Compares Washington to Authoritarian States#

The U.S. delegation walked out of a UN Security Council meeting on Monday when France’s ambassador took the floor to condemn Washington’s recent human rights voting record. The immediate trigger was France’s comparison of the U.S. to Russia, North Korea, and other authoritarian states — a reference to the U.S. joining those two countries in voting against extending Volker Turk’s term as UN High Commissioner for Human Rights. Turk’s four-year term renewal was backed by a broad majority; the U.S. was one of only a handful of countries to oppose it.

U.S. Ambassador Mike Waltz responded that Turk had shown a consistent pattern of criticizing democratic nations like the United States and Israel while “cozying up to the world’s worst oppressors,” and accused France of “disingenuous grandstanding.” The walkout is the latest in a series of public ruptures between Washington and European allies at the UN, following the U.S. voting pattern on human rights resolutions that has repeatedly placed it in the same column as states it would normally oppose. France and the U.S. are both permanent Security Council members; the row does not directly affect Council operations but signals a deepening transatlantic divide on international institutions.
