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.Veteran diplomat Alexander Vershbow, who served as U.S. ambassador to Russia and deputy secretary general of NATO, said the United States could not afford to be completely “agnostic” about how and when the war is concluded, given the U.S. interest in ensuring European security and deterring further Kremlin aggression beyond Russia’s borders.“But it is ultimately the Ukrainians doing the fighting, so we’ve got to be careful not to second-guess them.” While Zelensky laid out proposals for a negotiated peace in the weeks following Putin’s Feb. 24 invasion, including Ukrainian neutrality and a return of areas occupied by Russia since that date, Ukrainian officials have hardened their stance in recent months.That shift has been fueled by systematic atrocities in areas under Russian control, including rape and torture, along with regular airstrikes on Kyiv and other cities, and the Kremlin’s annexation decree."
