The President's intervention torpedoed an attempt to reassert the group's commitment to free trade and paper over the cracks in the western alliance exposed by Trump's controversial decision to slap tariffs on steel and aluminium. "You end up with gradual escalation".
Last week, Canada hit back at Trump administration by announcing retaliatory tariffs on up to 16.6 billion Canadian dollars (12.8 billion USA dollars) worth of US steel and aluminum as well as a diverse list of other products.
"He's a puncher or a counterpuncher, and he thrives on conflict", Hunter said.
Trump, during the summit, insisted that Russian Federation should be a part of the group, leaving many to wonder why the US president is going out of his way to include Vladimir Putin in the group. But that didn't stop the Twitteratis from drawing inferences about the kind of "power dynamics" was at play at the Summit, where Trump seemed to not be in sync with the rest of the United States allies, as was perhaps evident by his decision to not endorse the joint statement.
Economists and trade analysts note that the rules of world trade aren't as one-sided as the president argues.
The president also repeated claims that Canada overtaxes American dairy products under its supply management system and complained about Canadian automobiles entering the USA market.
He accused other states of "robbing" his country through their trade policies and proposed scrapping tariffs across the G7.
As a result, Hunter said, America has become "the world's leading IP-based economy".
He said USA representatives will examine the tariffs on automobiles coming into the country and bemoaned the Canadian tariffs that affect American companies and farmers. "I don't think that ratcheting up the rhetoric is going to improve things".
"What a happy thought", said Hunter, the trade lawyer.
Donald Trump, in a tirade against countries he said are "robbing" the U.S., targeted India once again on import tariffs, as he left the G-7 summit in Canada on bitter terms. The fears of a global trade war are coming truer by the day.
His comment sparked a new diplomatic spat between Trudeau and the Trump administration and led Chancellor Merkel to criticize Trump's handling of the matter.
Ten minutes later, the French President's office released a photo that shows Mr Macron negotiating with his American counterpart, gesticulating to make a point. And so we are talking to many countries.
White House economic adviser Larry Kudlow accused Trudeau of undermining Trump right before his meeting in Singapore with North Korean leader Kim Jong Un. "Canada has objected in words, but will also do so in actions", she said, referencing the retaliatory measures Canada will impose next month.
The US President addressed the subject of worldwide trade during an impromptu news conference at the summit Saturday, saying that he did not want to see other countries take advantage of the US over trade.
Despite the sharp differences, Trudeau said all seven leaders had come together to sign a joint declaration despite having "some strong, firm conversations on trade, and specifically on American tariffs".
