The diplomatic scaffolding for this week's Abu Dhabi talks is now visible, and its shape tells you where the leverage sits. Secretary of State Marco Rubio confirmed Sunday that "security guarantees" — the post-war architecture for Ukraine and Europe — have been the persistent throughline of US-mediated discussions. US envoys Steve Witkoff and Jared Kushner will represent Washington at Tuesday-Wednesday negotiations, while France's Foreign Minister Jean-Noël Barrot confirmed European participation without naming a specific representative. President Trump, in a "60 Minutes" interview broadcast Sunday, said he believed the war would end soon and that Ukraine could emerge "with a little bit different shape." Asked whether Putin was stringing him along, Trump replied: "Oh, I don't think so." The phrasing is significant. "Different shape" is the clearest public signal yet from a sitting US president that territorial concessions are on the table as a settlement baseline, not merely a Russian demand. Rubio's framing deserves close reading. By centring "security guarantees" rather than ceasefire mechanics or territorial lines, the US is attempting to shift the negotiation from what Ukraine loses to what Ukraine (and Europe) gains structurally. This is the classic mediator's move: reframe a zero-sum territorial dispute as an institutional design problem. Whether it works depends entirely on whether Russia treats the architecture discussion as genuine or as cover for a fait accompli on borders. On the ground, the war continues to impose asymmetric costs. A Russian drone struck emergency workers in Komyshuvakha, a village in southern Ukraine previously hit by bombs that killed at least 55 people last Monday; about 50 remain missing. Russia's defence ministry claimed overnight strikes hit three cargo vessels carrying military goods to Ukraine — one in Odesa, one in Chornomorsk, a third southwest of Odesa — plus two electricity substations powering Ukrainian defence industry. These are escalatory moves designed to erode Ukraine's logistics and morale during the negotiation window. The Zaporizhzhia nuclear plant lost external power for the 27th time since the conflict began, forcing backup generators to cool reactor fuel. The IAEA confirmed power was restored hours later but said the cause and location of the disconnection were unknown. Twenty-seven power losses at Europe's largest nuclear facility is not a statistic — it is a systemic fragility being normalised. Moldova offered a counterpoint to the fragility theme. President Maia Sandu launched a new power line connecting the country to Romania and the European grid, declaring: "For decades, Moscow used energy to blackmail us. No more. Moldova buys zero Russian gas." For a former Soviet republic of 2.6 million people, this is a concrete step toward energy sovereignty — the kind of infrastructure investment that reduces long-term extractive leverage. The overall picture: the US is building a negotiation framework around post-war security architecture while signalling acceptance of altered borders. Russia is simultaneously escalating strikes on civilian and logistics targets — a classic "negotiate from strength" posture. Europe is present but its representation remains ambiguous. Ukraine's leverage continues to erode with each week of infrastructure destruction, making the timing of any deal as consequential as its terms.
