What does President Trump claim about his ability to end the war in Ukraine?

President Trump claims he is the only person in the world who can end the Ukraine war and believes he has the power to do so. He asserts that if he had been in the White House three years ago, the conflict would never have begun. Trump appears to blame Ukraine for not making a deal with Russia prior to the invasion, suggesting that he would have forced negotiations between the parties. His statements imply that Vladimir Putin would not have dared to invade Ukraine had Trump been President of the United States.
