Ukraine, which was subject to a full-scale invasion in 2022 and saw Russia annex Crimea in 2014, says it needs security guarantees from the major powers - primarily the United States

Donald Trump has said he will be speaking to the presidents of Russia and Ukraine on Monday about stopping the 'bloodbath' in Ukraine. What are the challenges the U.S. president faces in his drive for a peace deal and what could such a deal look like?

As part of a failed 2022 deal, Ukraine would have agreed to permanent neutrality in return for security guarantees from the five permanent members of the U.N. Security Council: Britain, China, France, Russia and the United States, and other nations including Belarus, Canada, Germany, Israel, Poland and Turkey, according to a draft seen by Reuters.
