As President Trump takes office he inherits two international conflicts in which the United States is deeply involved. On the campaign trail he said he would be able to end the war between Russia and Ukraine. Last month he said there would be "hell to pay" if Hamas and Israel did not reach a ceasefire and hostage release deal before he assumed office. A temporary and fragile ceasefire began on Sunday. We hear from NPR correspondents in Israel, Russia and Ukraine to hear about those countries' expectations for the Trump presidency.
