When Air Force planes carrying Steve Witkoff and Jared Kushner touched down in Kyiv, the White House had already framed their preceding talks with Vladimir Putin as "substantive" — a word that, in diplomatic circles, is chosen precisely because it commits to nothing. The two senior American envoys arrived bearing a message of momentum; what they found, according to France 24 correspondent Gulliver Cragg reporting from the Ukrainian capital, was a city not yet willing to believe it. That scepticism is not irrational. Ukraine has endured more than three years of full-scale invasion, survived several rounds of internationally brokered ceasefire speculation, and watched each promising diplomatic signal dissolve before it produced a single kilometre of returned territory.

For many Ukrainians, the pattern has become familiar enough to be its own kind of warning. Officials in Kyiv have repeatedly insisted that any settlement must guarantee their country's security rather than simply freeze a front line that leaves Russia in a position to strike again. Those conditions have not visibly softened in Moscow. The broader context makes the mission harder still.

European governments, which had largely been sidelined during earlier rounds of US-Russia contacts, are watching Washington's bilateral approach with unease, fearing that a deal shaped without them could weaken the collective deterrence that underpins NATO's eastern flank. In Brasília and Beijing, meanwhile, both governments have expressed interest in contributing to any eventual peace framework, a reminder that the war's diplomatic geography now extends well beyond the Atlantic alliance. Whether Witkoff and Kushner can translate White House optimism into terms that Kyiv can accept — and that Moscow will not simply pocket — remains the question that every previous envoy has also failed to answer.
