The Biden administration is privately encouraging Ukraine’s leaders to signal an openness to negotiate with Russia and drop their public refusal to engage in peace talks unless President Vladimir Putin is removed from power, according to people familiar with the discussions.

The request by American officials is not aimed at pushing Ukraine to the negotiating table, these people said. Rather, they called it a calculated attempt to ensure the government in Kyiv maintains the support of other nations facing constituencies wary of fueling a war for many years to come.

The discussions illustrate how complex the Biden administration’s position on Ukraine has become, as U.S. officials publicly vow to support Kyiv with massive sums of aid “for as long as it takes” while hoping for a resolution to the conflict that over the past eight months has taken a punishing toll on the world economy and triggered fears of nuclear war.

While U.S. officials share their Ukrainian counterparts’ assessment that Putin, for now, isn’t serious about negotiations, they acknowledge that President Volodymyr Zelensky’s ban on talks with him has generated concern in parts of Europe, Africa and Latin America, where the war’s disruptive effects on the availability and cost of food and fuel are felt most sharply.

“Ukraine fatigue is a real thing for some of our partners,” said one U.S. official who, like other interviewed for this report, spoke on the condition of anonymity to discuss sensitive conversations between Washington and Kyiv.
