Controversies
U.S. President Donald Trump said French President Emmanuel Macron's November comment that NATO was in a state of "brain death" for its reaction to the 2019 Turkish offensive into north-eastern Syria was "very, very nasty." The two leaders disagreed about terrorism, trade, and France's contributions to NATO's budget. Trump mentioned the possibility of France "breaking off" from NATO, although Macron made no such suggestion.
Trump and U.K. Prime Minister Boris Johnson did not meet because Johnson was concerned about Trump's possible interference with the UK general election on 12 December.
While meeting with Canadian Prime Minister Justin Trudeau, Trump complained that Canada is "slightly delinquent" in its contribution to NATO because it pays less than 2% of its GDP on the military. The two leaders had a friendly discussion about the United States–Mexico–Canada Agreement. Later, during a reception at Buckingham Palace, Trudeau, Johnson, Macron, and Dutch Prime Minister Mark Rutte seemed to mock Trump because of a 45-minute press conference. In turn, Trump called Trudeau, "two-faced," referencing Canada's military spending.
Turkish President Recep Tayyip Erdoğan insisted that NATO members formally recognize the Kurdish YPG as a terrorist organization.
