Canada and Mexico, the other members of NAFTA, have been frustrated by what they see as unacceptable United States demands in slow-moving talks to modernize the deal.
But when it came to America's adversaries, Trump was in full suck-up mode. And they made light of the disputes.
"We spend two days working out a [joint] statement and commitments". The consensus documents typically outline a shared vision of global affairs, where the seven countries also undertake commitments on everything from currencies, development aid and worldwide security.
Macron launched the offensive on Thursday at a joint news conference with Canadian Prime Minister Justin Trudeau. "Everyone agreed, including President Trump". "And that's the key point", Trump said.
"When we're at war with our allies, if we need something, we don't have them to turn to", said Conley, now with the Center for Strategic and International Studies in Washington.
But for Trump, infuriating allies with fake facts is just another day at the office.
And Trump has done little to ease their jitters.
And at the same time as western nations are at loggerheads, the United States president seems more at home with autocrats than with Washington's traditional allies.
This will be Trump's second summit of the G-7, an informal gathering that meets every year under a rotating chairmanship. He's proven himself to be a leader on the world stage. Few expect the assembled leaders will even agree on language for a joint "communique" that typically concludes the summit.
While posing for photographs at the summit Macron, 40, patted Trump, 71, on the arm and then grabbed his hand to shake it. But the group retreated quickly behind closed doors for the start of their talks.
Across a narrow table, German Chancellor Angela Merkel and French President Emmanuel Macron are standing, holding copies of a draft text, arguing for their position. "I think the bilateral meeting that's scheduled between the two is a really good thing and I think they'll walk through a lot of these issues".
Although Trump and Kudlow have since claimed Trudeau "stabbed us in the back" and was the reason for the U-turn, it is Trump's actions that other G7 leaders appeared to find frustrating.
Kylie Jenner Deletes All Photos Of Stormi's Face From Instagram
And the reality TV star hit back when social media users questioned why she had cropped Travis Scott's daughter out of the image. Following her response, Kylie removed every photo that shows Stormi's face, leaving only those that merely show her presence.
"Emmanuel's been very helpful in that regard", Trump said.
When Trump met with Macron in France past year, the two shared an intense handshake that saw both men clench their fists until their knuckles turn white. The relationship between the two alpha males has been something of a rollercoaster ride since they first met previous year.
Trump has been less friendly with Trudeau, who he views as overly liberal, according to aides. There are differences in styles of diplomacy and views about cooperation and free trade.
But less than 24 hours later the two men were facing each other in white armchairs, grinning ahead of face-to-face talks. That means Trump "is right to a certain extent" when he criticizes Germany for spending only 1.3% of economic output on defence, Merkel said.
"We're going to deal with the unfair trade practices".
In Canada, Trump is confronting a fractured set of Western alliances that he has shown little desire to fix.
Trump made the comments in tweets from Air Force One as he headed to Singapore for his summit with North Korea's Kim Jong Un.
The proposal was supported by other leaders present, the official said.
Russian Federation was expelled following Vladimir Putin's annexation of Crimea in 2014, which Mr Trump characterised as "something happened a while ago".
"Russia should be in this meeting", Trump said.
European Council President Donald Tusk, who will attend the meeting of EU leaders, said in the New York Times this week "Europe must now do everything in its power to protect the trans-Atlantic bond, in spite of today's mood".
