Trump to pitch 'Board of Peace' at Davos after walking back Greenland threats

US President Donald Trump will show off his new "Board of Peace" and meet Ukraine's leader at Davos on Thursday -- burnishing his claim to be a peacemaker a day after backing off his own threats against Greenland. Trump said he was due to hold talks with Ukrainian President Volodymyr Zelensky after the "Board of Peace" meeting as difficult negotiations for a ceasefire in the Ukraine war continue.
