German Chancellor Merz said the current form of US President Trump’s “Board of Peace” prevented Germany from joining for “constitutional reasons.” But Merz said he was open to “new formats” of cooperation with the US.

German Chancellor Friedrich Merz said he is open to new dialogue with the United States, but added that he would not join US President Donald Trump’s so-called Board of Peace as it currently stands.
“We are, of course, ready to explore other forms, new forms of cooperation with the United States of America,” he said at a press conference in Rome on Friday.
Merz had previously expressed his willingness to participate in such a body to Trump weeks ago, but he added that what it has now become cannot be accepted by Germany in its current structure “on constitutional grounds.”
Germany ready for more cooperation with US
The rejection adds Germany to the list of traditional US allies that said they would not join the board, including France, the UK and Spain.
Saudi Arabia, Hungary and Qatar have confirmed their spots on the US board, which some observers see as a way to circumvent the United Nations.
