WATFORD, England (AP) — Aiming to play the role of global statesman as the impeachment drama was unfolding in Washington, President Donald Trump instead shattered NATO’s professed message of unity at its 70th anniversary celebration in England and put his personal and policy differences with alliance members on stark display.

Trump called Canadian Prime Minister Justin Trudeau “two-faced” and French President Emanuel Macron “nasty” during a 52-hour trip that exposed the alliance’s divisions on military budgets and relations with Turkey, as well as the U.S. leader’s own unconventional ways on the world stage.

At the same time, he found it difficult to leave behind events in Washington, lashing out as House Democrats resumed their push for impeachment over Trump’s call for Ukraine to investigate a political rival. He said it was “sad” that Democrats were pushing ahead with the inquiry when “there was no crime whatsoever and they know it.”

Trump, looking to showcase foreign policy wins as he heads into an election year, offered a more optimistic outlook for NATOs future. He took credit for boosting the share of NATO nations that are meeting the alliance’s goal of spending 2% of gross domestic on defense and sought to pressure more countries to increase their military budgets. But he also put a spotlight on his administration’s lingering to-do list: ending a China trade war he instigated, passing the U.S.-Mexico-Canada agreement as well as trade deals with the European Union and Britain.

A day after Trudeau was overheard gossiping about Trump during a reception at Buckingham Palace, Trump called the Canadian leader “two-faced.” In an unguarded conversation, Trudeau told leaders, including Macron and British Prime Minister Boris Johnson, that “he takes a 40-minute press conference off the top,” an apparent reference to Trump’s long and unscheduled question-and-answer session with journalists earlier that day.

Trudeau also said, seemingly about his meeting with Trump: “You just watched his team’s jaws drop to the floor.”

Trump fired back during a Wednesday afternoon meeting with German Chancellor Angela Merkel. He suggested that the Canadian’s overheard comments were precipitated by Trump’s decision to highlight the fact that Canada falls short of NATO goals on defense spending.

“The truth is that I called him out on the fact that he’s not paying 2% and I guess he’s not very happy about it,” Trump said. Later, seeming to relish the spat, Trump remarked “That was funny when I said that guy was two-faced.”

Relations between Trump and Macron, once the American president’s closest European ally, deteriorated a day earlier in feisty exchanges on live television.
