Vice President JD Vance has issued an ultimatum to Ukraine and Russia over America's peace proposal to end the war. "It's time for them to either say yes or for the United States to walk away from this process," he told reporters during his visit to India, shortly before boarding Air Force Two on Wednesday.

A peace plan that would leave Russian forces deep inside eastern Ukraine would be welcome news in Moscow. President Vladimir V. Putin has said for almost year that he would accept a cease-fire in which Ukraine withdraws troops from the four regions that Moscow has claimed as its own and drop its aspirations to join NATO.

Vice President JD Vance warned Russia and Ukraine that the U.S. could "walk away" if the two countries do not strike a deal to end the ongoing war.
