US President Donald Trump is moving forward with his “Board of Peace,” initially designed to help implement a Gaza ceasefire, with ambitions to expand its mandate to other global conflicts, potentially creating a parallel to the United Nations.

In letters sent Friday, Trump invited world leaders—including Argentina’s Javier Milei, Paraguay’s Santiago Peña, Canadian Prime Minister Mark Carney, Egyptian President Abdel-Fattah el-Sissi, and Turkish President Recep Tayyip Erdogan—to serve as founding members. Trump described the board as “the most impressive and consequential board ever assembled,” envisioning it as an international organization and transitional governing body.

Trump’s 20-point Gaza ceasefire plan, endorsed by the U.N. Security Council, serves as the framework for the Board of Peace, but letters suggest the body could extend beyond Gaza to address other global crises. A senior U.S. official said an expanded role is “aspirational” and aimed at addressing frustrations with the United Nations’ bureaucracy, though the board is not intended to formally replace the U.N.

Critics argue the initiative could undermine established international norms. Daniel Forti of the International Crisis Group said it allows the U.S. to sidestep traditional mechanisms for sovereignty and territorial integrity, potentially shaping global conflicts to Washington’s interests.

An executive committee overseeing Gaza already includes U.S. officials, business leaders, and former international figures such as Tony Blair and World Bank President Ajay Banga. Israel has objected, saying the board’s plans were not coordinated with its government.

The White House plans a formal announcement of the board and its members next week at the World Economic Forum in Davos, Switzerland, amid questions over its potential impact on the post-World War II international order.
