U.S. President Donald Trump on Thursday promised $10 billion and Muslim-majority nations offered funding and troops for Gaza as he inaugurated his “Board of Peace,” a new institution whose ultimate mission has drawn questions.

The Vatican already announced it will not participate in Trump’s ‘Board of Peace, insisting that global conflict management should remain the responsibility of the United Nations (UN). The position was disclosed by the Holy See Secretary of State, Cardinal Pietro Parolin, who said the Church was “perplexed” by aspects of the initiative.

“At the international level, it should above all be the UN that manages these crisis situations. This is one of the points on which we have insisted,” Parolin told reporters.

The board — originally proposed to oversee reconstruction in Gaza — has since been expanded into a global peacekeeping body to be chaired indefinitely by Trump.

Trump brought together allies from around the world — many authoritarians, with few Western democrats who traditionally ally with the United States — to hail his peacemaking just as he sends U.S. military might near Iran and threatens war.

Presiding with a gavel over the meeting in the gleaming Washington building of the former U.S. Institute of Peace, which has been gutted and renamed after the 79-year-old Republican, Trump hailed the “powerful people” who joined his board.

“We will help Gaza. We will straighten it out. We’ll make it successful,” Trump said, holding up a document with pledges before the disco beats of his adopted theme song “YMCA” came on the speakers.
