President Donald Trump’s “Board of Peace” that was initially seen as a mechanism focused on ending the Israel-Hamas war in Gaza is taking shape with ambitions to have a far broader mandate of other global crises. It could mean potentially rivaling the United Nations in what would be a major upheaval to the post-World War II international order. In letters sent Friday to various world leaders inviting them to be “founding members” of the board, Trump says the body would “embark on a bold new approach to resolving global conflict.” Leaders from Argentina, Paraguay, Canada, Egypt and Turkey have been invitated to join the board, according to their governments.
