A large majority of Americans continue to support Ukraine’s war effort, backing ongoing arms supplies and supporting additional sanctions on Russia, according to the latest Harvard CAPS / Harris Poll released on 6 October.
The poll, conducted online by The Harris Poll and HarrisX on 1–2 October 2025 among 2,413 registered American voters, reflects persistent cross-partisan approval for the US role in Ukraine's defense.
According to the poll, 68% of respondents believe a future Trump administration should both tighten sanctions on Russia and continue supplying weapons to Ukraine. Both Democrat (72%) and Republican (73%) voters support the arms supplies and new sanctions.
While 57% support imposing tariffs on countries that buy Russian oil and gas, 79% of those surveyed think Europe should stop buying oil from Russia and turn to the United States instead.
Zelenskyy among most popular global figures in the US, Ukraine as popular as NATO
Ukrainian President Volodymyr Zelenskyy remains one of the most favorably viewed international figures among American voters, with 29% rating him as favorable or very favorable. According to the latest Harvard CAPS / Harris Poll, he ranks seventh overall in net favorability, behind Donald Trump, Charlie Kirk, Robert F. Kennedy Jr., Joe Biden, JD Vance, and Elon Musk.
Zelenskyy’s favorability exceeds that of US officials such as Senator Marco Rubio, House Speaker Mike Johnson, and Secretary of War Pete Hegseth, who were also included in the survey. In the very favorable metric, Zelenskyy (16%) ranks ahead of Musk (15%) and matches Kennedy and Biden.

In the “favorability of institutions” ranking, Ukraine places seventh — slightly behind Harvard University and slightly ahead of NATO in overall favorability — while sharing the same 17% “very favorable” rating as NATO.

Most Americans support Trump’s peace efforts — but doubt his chances of ending the war
While 65% of Americans support US President Donald Trump’s efforts to end Russia's war in Ukraine, a 63% majority say he will not be able to actually solve the conflict, according to the same poll.
