We begin in Tehran, where Iran's security chief Mohsen Rezaei has flatly rejected proposals to move enriched uranium OUT of the country — telling a visiting Pakistani delegation that Iran's nuclear sovereignty is NON-NEGOTIABLE. ... This is a significant hardening of position. Pakistan has been the primary diplomatic back-channel between Washington and Tehran since the summer's ceasefire, and Islamabad's mediation efforts now face a concrete obstacle: any deal that requires physical transfer of enriched material appears, for now, to be off the table. ... Watch whether U.S. envoy Steve Witkoff — who travels to St. Petersburg on Tuesday to meet Russian officials on European and American proposals — returns with any new framework that can break this impasse. The diplomatic geometry here matters: Russia is simultaneously a guarantor candidate for any eventual Iran deal AND an active belligerent in Eastern Europe — two roles that increasingly pull in opposite directions.

And it is that very tension — between diplomatic engagement and battlefield reality — that defines today's picture in Ukraine. ... Ukrainian forces struck Yandex data centres in what military intelligence described as a targeted operation — the strikes reportedly disrupted Russian court hearings and caused power outages across Sumy Oblast. Ukraine's HUR claimed one hundred and eight Russian soldiers killed and twenty-nine captured in a single Sumy operation. ... Separately, Ukraine's Security Service has charged a Russian occupation official in Zaporizhzhia Oblast with war crimes — the official headed the department responsible for religious organisations within Russia's occupation administration. ... The Witkoff mission to St. Petersburg unfolds against THIS backdrop: active operations, active prosecutions, and a front line that shows no sign of freezing. What to watch: whether Witkoff returns with anything that Kyiv can credibly engage with — or whether the St. Petersburg talks remain a parallel track DISCONNECTED from the war's daily arithmetic.

The infrastructure of INFORMATION is itself now a theatre of conflict — and nowhere is that clearer than in today's AI developments. ... Washington has ordered all federal civilian agencies to REMOVE DeepSeek — China's flagship AI system — from their networks entirely, citing national security concerns. That order extends to third-party services built on DeepSeek's underlying technology. ... The timing is pointed. On the same day, a Google cloud outage took down UK banking services — including Revolut — for hours, demonstrating just how concentrated critical financial infrastructure has become inside a handful of technology providers. ... And in New York, mayoral candidate Zohran Mamdani publicly argued that the federal government has ABDICATED on AI governance entirely — urging state-level action to protect citizens. The picture that emerges is a governing vacuum: Washington banning one foreign AI system while offering NO coherent framework for the domestic AI economy that is already reshaping banking, warfare, and the infrastructure of democratic accountability. ... That vacuum does not stay empty for long.
