The Washington Post and Bloomberg reported the information.President Donald Trump intensified pressure on Ukrainian President Volodymyr Zelenskyy over the weekend, demanding a response to his administration's peace proposal by Thursday or warning Ukraine would have to "continue to fight his little heart out." The ultimatum comes as the White House pushes a 28-point plan to end the war that has drawn sharp criticism from both European allies and Republican lawmakers for making substantial concessions to Russia.The U.S. proposal, drafted with Russian input by Trump's special envoy Steve Witkoff and Russian envoy Kirill Dmitriev, would require Ukraine to cede territory to Russia, significantly reduce its armed forces to 600,000 personnel, and bar NATO troops from Ukrainian soil. Ukraine would also need to withdraw from parts of eastern Donbas that Russia has failed to fully occupy, creating a demilitarized buffer zone that would be internationally recognized as Russian territory.European leaders swiftly responded with a counterproposal on the sidelines of a Group of 20 meeting in Johannesburg on Saturday. More than a dozen leaders, including French President Emmanuel Macron and German Chancellor Friedrich Merz, drafted an alternative plan calling the original U.S. proposal "a basis which will require additional work."The European response fundamentally differs from the American plan on several key points. Most significantly, it rejects any restrictions on Ukraine's armed forces, which European leaders say "would leave Ukraine vulnerable to future attack." Instead of limiting troop numbers, the counter-proposal suggests a higher cap could be negotiated, with Ukraine previously stating it needs at least 800,000 troops during peacetime.According to the European plan, Ukraine would regain control of the Zaporizhzhia Nuclear Power Plant and the Kakhovka Dam, with "unhindered passages" on the Dnipro River and control of the Kinburn Split. The proposal stipulates that discussions on any territorial swaps could only occur after a ceasefire is established along the current line of contact.Crucially, the European response demands robust security guarantees from the United States that mirror NATO's Article 5 mutual-defense clause. The plan also calls for frozen Russian assets to be used for Ukraine's reconstruction and compensation, with those assets remaining frozen unless Moscow agrees to pay for war damages. Other sanctions would be lifted progressively as Russia abides by the agreement and is gradually reintegrated into the global economy."We reiterate that the implementation of elements relating to the European Union and relating to NATO would need the consent of E.U. and NATO members," the European leaders said in their joint statement.Senior European officials from France, Germany, and Britain are scheduled to join talks on the Ukraine peace plan in Geneva on Sunday, where national security advisors from the U.S., Ukraine, and Europe will discuss both proposals.The U.S. plan has also encountered resistance within Trump's own party. Sen. Lindsey Graham wrote on X that "several areas" of the proposal "are very problematic and can be made better," emphasizing that "the fate of the almost 20,000 Ukrainian children kidnapped by Putin's forces" must be addressed."This so-called 'peace plan' has real problems, and I am highly skeptical it will achieve peace," said Sen. Roger Wicker, chairman of the Senate Armed Services Committee. "Any assurances provided to Putin should not reward his malign behavior or undermine the security of the United States or allies."Sen. Mitch McConnell warned that "rewarding Russian butchery would be disastrous to America's interests," while Sen. Tim Scott voiced support for imposing "tough, targeted sanctions on Russia to weaken Putin's war machine."Russian leader Vladimir Putin told his security council Friday that the U.S. proposal could serve "as the basis for a final peace settlement," though he claimed the U.S. had not discussed the plan in detail with Russia. "Russia is ready for peace talks and peaceful resolution of problems. But this requires, of course, a substantive discussion of all the details of the proposed plan," Putin said.When asked if his proposal was a final offer, Trump responded, "No," adding, "I would like to get the peace. It should have happened a long time ago. … We're trying to get it ended. One way or the other we have to get it ended."On November 19, Axios reported that the White House is quietly working with Moscow on a comprehensive framework to end the war in Ukraine, drawing inspiration from the recent Gaza ceasefire deal.According to Reuters, the U.S. has signaled to President Volodymyr Zelenskyy that Ukraine must accept a U.S.-drafted framework to end the war with Russia that proposes Kyiv giving up territory and some weapons.On November 21, the British publication The Telegraph published the full list of the 28 points of the U.S. peace plan, which Washington is proposing to Ukraine and Russia as a basis for ending the war. The document reportedly involves significant concessions from Kyiv, but does not prohibit it from joining the EU.Donald Trump has stated that the U.S. is demanding Ukrainian leader Volodymyr Zelenskyy sign a peace agreement by Thanksgiving on November 27. At the same time, the United States has increased pressure on Ukraine, threatening to halt the supply of weapons and intelligence.
