In an interview with Fox radio, Trump said that Ukraine risks losing even more territory"in a short period of time."

Regarding the deadline until next Thursday, which is Thanksgiving Day in the US, Trump said it could be extended if everything"goes well", but overall, he said, it is"the right time".

So far, Trump has not commented on the peace offer published in the media.

Washington has proposed a plan to end the war in Ukraine that appears to be based largely on Russian demands. It includes not only the retention of occupied territories under Russian control, but also Ukraine's commitment not to join NATO, not to expand the alliance and Russia's return to the G8, according to a draft of the plan obtained by AFP.

The plan states that Ukraine would hand over to Russia those parts of Donetsk and Luhansk regions that it does not already control. The Donetsk and Luhansk regions, as well as Crimea, would be recognized as de facto Russian-controlled territories, and a demilitarized zone would be established in Donbas. Meanwhile, in the Zaporizhia and Kherson regions, which Russia has declared its territory but does not fully control, the front line would be frozen. Russian troops would have to leave the occupied territories in other regions of Ukraine.

Once all parties agreed to the plan and both sides withdrew to the agreed points to begin implementing it, an immediate ceasefire would come into effect. Both sides would be granted amnesty covering wartime offenses.

Kiev would also have to reduce the size of its army by slightly less than half - to 600,000.

There are no strict military restrictions on Russia. The plan states that"it is expected that Russia will not invade neighboring countries and that there will be no further expansion of NATO," and that NATO will not deploy troops in Ukraine.

Russia should establish a policy of non-aggression against Europe and Ukraine by law, and the United States and Russia should extend nuclear arms control and non-proliferation treaties, including START I.
