Public opinion radicalizes
In Russia, before Trump entered the picture, attitudes were relatively balanced: roughly half of respondents supported ending hostilities, while about the same share preferred to continue the war. Trump’s provocative statements in February, however, shifted Russian public opinion toward a more hawkish stance. The proportion of Russians unwilling to accept compromises in a settlement with Kyiv rose from 32% in autumn 2024 to 42% in March 2025. Despite the widespread fatigue with the protracted conflict (around half the population acknowledges that the war is negatively affecting their lives), state propaganda during this period portrayed Trump as a politician who “understands Russia” and is prepared to take its interests into account. This messaging reinforced perceptions of Russia’s military advantage and even encouraged demands to “keep fighting a little longer.” Because of the “Trump effect,” support for the military campaign temporarily increased, rising from roughly 50% to 57% at the peak of his declared peace push in early March.
In Ukraine, too, hope for a quick ceasefire initially rose, with a significant segment of society expressing readiness to make concessions for the sake of ending the war. In early 2025, about 40% of Ukrainians were willing to consider suspending offensive operations if it helped secure a peace agreement. Yet the infamous meeting between Zelensky and Trump on February 28 in the White House – which many Ukrainians viewed as humiliating for their country – sharply altered public sentiment: the share of respondents willing to compromise for peace fell to 33%, while support for fighting until full liberation of Russia-occupied territory rose from approximately 49% to 57%. In other words, most Ukrainians became markedly more uncompromising after that episode, rejecting the notion of a “bad peace,” on terms perceived as favorable to the Kremlin.
A mediator lacking trust
The pro-Russia tilt of Trump’s peace proposals went unnoticed neither in Kyiv nor in Moscow. The majority of Ukrainians, as well as a significant share of Russians, believed that Trump was acting in Russia’s interests. Earlier in the year, 72% of respondents in Ukraine and 43% in Russia held this view; by autumn, the latter figure had sunk to 32%. Overall trust in the US president remains extremely low: only about 12% of Ukrainians and 20% of Russians trust him. Many in Russia see him as a foxy and inconsistent politician, with more than half of Russians opining that even Putin does not trust him (and vice versa). As of autumn, only a third of Russians now say that Trump is genuinely seeking a ceasefire, versus the three quarters who believe in Putin’s peaceful intentions. In Ukraine, over 50% of the population believes that Trump is trying to pressure Kyiv into making dangerous territorial concessions to satisfy the Kremlin.
Overall, the upshot is that, in these conditions, no mediation can succeed: the mistrust on each side means that Trump’s initiatives have been seen by Russians as unreliable and by Ukrainians as forced on them and as threatening their country’s sovereignty.
