US-Iran tensions threaten Ukraine peace talks as temporary strike pause holds

Millions of Ukrainians face extreme winter conditions without electricity or heating as temperatures plummet to -26°C, creating humanitarian crisis alongside ongoing conflict.
Something is happening between the United States and Iran, and those developments could affect the timing.
Zelenskyy explaining why planned peace talks in Abu Dhabi might be postponed or relocated.

On the 1,438th day of a war that has reshaped the European order, a fragile pause in strikes on Ukraine's power infrastructure offers millions of freezing civilians a rare night of warmth — yet the diplomatic machinery meant to build on this moment is stalling, pulled apart by the gravitational force of a separate crisis unfolding between Washington and Tehran. Peace talks scheduled for Abu Dhabi this Sunday now hang in suspension, their American architects redirected elsewhere, their promise dimming before it could fully form. History reminds us that the distance between a pause and a peace is vast, and that the world's crises rarely wait their turn.

  • Zelenskyy publicly acknowledged Friday that US-Iran tensions may force the postponement of critical Ukraine-Russia negotiations in Abu Dhabi, stripping the talks of their American architects before they could begin.
  • Trump's envoys Witkoff and Kushner have been pulled from the Abu Dhabi table entirely, with Russia's negotiator Kirill Dmitriev rerouted to Miami instead — the machinery of diplomacy grinding sideways.
  • A fragile, unacknowledged pause in strikes on energy infrastructure has kept the lights on in some Ukrainian cities since Thursday, but the Kremlin's own spokesman suggested the arrangement would expire Sunday.
  • Millions of Ukrainians face temperatures plummeting to -26°C without reliable electricity or heating, meaning the survival of this informal truce is not a diplomatic abstraction but a matter of life through the winter.
  • Europe is fracturing over how to respond — the Netherlands insisting on continued support with no dialogue with Moscow, while Hungary's Orbán weaponizes Ukraine's EU accession bid ahead of his own April elections.

On the 1,438th day of the war, something unusual happened: the strikes on power plants stopped. Not officially, not by any signed agreement, but by what Zelenskyy described as a reciprocal understanding — if Russia refrained from hitting Ukraine's energy infrastructure, Ukraine would do the same. Trump claimed Putin had agreed to a one-week halt. The Kremlin neither confirmed nor denied it. By Friday morning, both sides appeared to be honoring it, and for the first time in weeks, some Ukrainian cities had heat through the night.

The pause was fragile from the start, and now it is threatened by something far away. Ukraine's senior officials were due in Abu Dhabi on Sunday to meet Russian negotiators, with American envoys Steve Witkoff and Jared Kushner expected to attend as they had in the previous round. But rising tensions between Washington and Tehran have scrambled those plans. Zelenskyy acknowledged publicly that the date and location might change. The secretary of state confirmed the American envoys would not be coming. Russia's negotiator was rerouted to Miami. The talks, already uncertain, risk becoming theater — or not happening at all.

The human stakes make the diplomatic paralysis harder to absorb. Millions of Ukrainians are living without electricity or heating in one of the coldest winters in decades, with Kyiv bracing for minus 26°C starting Sunday. In this context, the pause in energy strikes is not a diplomatic milestone — it is a matter of survival.

Across Europe, the fractures are deepening. The Netherlands' incoming prime minister pushed back against calls to reopen channels with Moscow, insisting there were no signs Russia wanted peace and that Europe must build its own capacity for action rather than deferring to Washington. In Hungary, Viktor Orbán was escalating his campaign against Ukraine's EU membership bid, framing the accelerated 2027 accession timeline as a threat — a position shaped as much by his own April elections as by principle. The war in Ukraine has become a domestic political instrument across the continent, even as the people it most directly concerns endure the dark and the cold.

On day 1,438 of the war, Ukraine and Russia have stopped shooting at each other's power plants. It is not a ceasefire. It is not even officially acknowledged by Moscow. But for the first time in weeks, the lights have stayed on in some cities, and people have had heat through the night. The pause is fragile, temporary, and now threatened by something happening thousands of miles away—in the space between Washington and Tehran.

Ukrainian president Volodymyr Zelenskyy was supposed to send senior officials to Abu Dhabi on Sunday to sit across a table from Russian negotiators. The Americans were supposed to be there too: Steve Witkoff and Jared Kushner, Trump's envoys, who had attended the previous round. But on Friday, Zelenskyy acknowledged what everyone already suspected. "The date or the location may change," he said. "Something is happening in the situation between the United States and Iran, and those developments could affect the timing." The secretary of state had already confirmed that Witkoff and Kushner would not be coming. In Moscow, Putin's special envoy Kirill Dmitriev was being rerouted to Miami instead, to meet with Trump's people there. The machinery of negotiation was grinding to a halt before it had properly started.

What made this moment fragile was the weather and what it had already done to Ukraine. The country was experiencing one of its coldest winters in decades. Millions of people were living without electricity or heating. Kyiv itself was bracing for temperatures to drop to minus 26 Celsius starting Sunday. In this context, the pause in strikes on energy infrastructure was not a diplomatic victory—it was a matter of survival. Trump had claimed on Thursday that Putin had agreed to halt attacks on Ukraine's power grid for a week. The Kremlin acknowledged the request but would not confirm the agreement, though a spokesman suggested it would end on Sunday. Zelenskyy said there was no formal ceasefire, only a reciprocal understanding: if Russia stopped hitting power plants, Ukraine would do the same. By Friday morning, both sides appeared to be honoring it. "In all regions, there were indeed no strikes on energy facilities from Thursday night to Friday," Zelenskyy said. "Ukraine is ready in reciprocal terms to refrain from strikes and today we did not strike at Russian energy facilities."

The stakes of the Abu Dhabi talks were enormous precisely because they were so uncertain. Zelenskyy emphasized that he needed everyone who had been part of the previous negotiations to show up. "Everyone is expecting feedback," he said. Without the American envoys, without clarity about Russian intentions, without even a confirmed date or location, the talks risked becoming theater—a meeting that happened but resolved nothing, or worse, did not happen at all.

Meanwhile, fractures were widening in Europe. The incoming Dutch prime minister, Rob Jetten, pushed back against suggestions from some EU leaders that Europe should reopen diplomatic channels with Russia to prevent Trump from monopolizing negotiations. Jetten said his new government would continue supporting Ukraine and would not speak to Moscow because there were "no indications" Russia wanted to end the war. "As long as the aggression continues, we will continue our support for the Ukrainian people," he said. He also called for Europe to stop looking to the United States and develop its own capacity for action.

In Hungary, Viktor Orbán was escalating his opposition to Ukraine joining the European Union, claiming the bloc wanted to fast-track membership in 2027 to allow Ukraine to access the next seven-year budget cycle. Zelenskyy had made 2027 his target for EU accession, but skepticism about the accelerated timeline was real. Orbán's public campaign against it was likely also calibrated for his own political survival—parliamentary elections in April could end his 16 years in power. The war in Ukraine was becoming a domestic political weapon across Europe, even as the people of Ukraine froze in the dark.

The date or the location may change. From our point of view, something is happening in the situation between the United States and Iran, and those developments could affect the timing.

Why does the US-Iran situation matter to peace talks that are supposed to be about Ukraine and Russia?

Model

Because Trump's envoys were supposed to be in Abu Dhabi to represent American interests and guarantees. If the US is preparing military action against Iran, those envoys stay in Washington. The talks lose their anchor.

Inventor

But couldn't the talks happen without them?

Model

Technically yes. But Zelenskyy was clear: everyone who was at the last round needs to be there. Without the Americans, there's no one to broker a deal, no one to promise enforcement. It becomes a conversation between two sides with no mediator.

Inventor

What about the pause in strikes? That seems like progress.

Model

It is, but it's also a hostage to the weather and to Trump's word. It lasts a week, maybe. Kyiv is about to get hit with minus 26 degree cold. If the pause breaks, people die from cold as much as from bombs.

Inventor

Is Orbán trying to sabotage Ukraine's EU bid?

Model

He's using it. The EU accession question is real and complicated, but Orbán is making it a campaign issue for his own election. He's betting that opposing Ukraine plays well with his base.

Inventor

So the talks might not even happen?

Model

They might happen in a different place, at a different time, with different people. Which means they might not accomplish anything. Or they might happen and still not accomplish anything. Right now, no one knows.
