Abusing his international counterparts has become a signature strategy of the Republican firebrand. In June, the US President called Justin Trudeau, the prime minister of Canada, “very dishonest and weak” at the end of the G7 summit. Trump attacked Mr Trudeau over trade and was angered at criticism from his Canadian counterpart.
A spokesperson for the Canadian prime minister said at the time: “The prime minister said nothing he hasn’t said before, both in public and in private conversations with the President.”
The Republican also lambasted the Chancellor of Germany, Angela Merkel, in June.
He said: “The people of Germany are turning against Ms Merkel’s leadership as migration is rocking the already tenuous Berlin coalition.”
He also threw sweets at the German leader during a G7 meeting in June.
He said: “Don’t say I never give you anything.”
In July, Trump told the Sun Theresa May had “wrecked” Brexit.
He later said his own interview with the newspaper was “fake news”.
Trump went on to threaten the President of Iran, Hassan Rouhani, in July.
He said: “You will suffer consequences the likes of which few throughout history have ever suffered before.
“We are no longer a country that will stand for your demented words of violence and death.
Trump’s comments came after Mr Rouhani said a war between Iran and the US would be “the mother of all wars”.
However, the Iranian leader also insisted “peace with Iran is the mother of all peace”.
During a meeting with Shinzo Abe, prime minister of Japan in August, Trump reportedly said “I remember Pearl Harbor,” in what diplomats said was a threat toward his Japanese counterpart.
The property tycoon later said the meeting between the pair was “tense”.
In September he threatened Nicolas Maduro, the President of Venezuela, by saying the US could easily overthrow his government.
He said: “It’s a regime that, frankly, could be toppled very quickly by the military if the military decides to do that.”
Trump’s administration has also labelled Venezuela, Cuba and Nicaragua the “troika of tyranny”.
The President slammed Emmanuel Macron in November after the French President suggested the EU should build a military to protect against threats from China, Russia and the US.
The billionaire tweeted: “Emmanuel suffers from a very low Approval Rating in France, 26 percent, and an unemployment rate of almost 10 percent.
“He was just trying to get onto another subject.
Trump added: “There is no country more Nationalist than France.”
Mr Macron said in response: “Between allies, respect is due.
“I don’t think the French expect me to respond to tweets but to continue this important history.”
