Commentators saw a parallel in past tensions between Trudeau's father and Richard Nixon, when the then-leader of the United States called Trudeau senior, in private conversations, a "pompous egghead" and a "clever son of a bitch". "Not fair to the PEOPLE of America!" he tweeted.
"Germany pays 1 percent (slowly) of GDP towards North Atlantic Treaty Organisation, while we pay 4 percent of a MUCH larger GDP", he wrote, saying that the USA was protecting Europe and being "clobbered on trade" in return.
"Germany pays 1 percent (slowly) of GDP towards North Atlantic Treaty Organisation, while we pay 4 percent of a much larger GDP".
The former Conservative prime minister said that while he believes the dispute is serious, that doesn't make it "lethal". We protect Europe (which is good) at great financial loss, and then get unfairly clobbered on Trade.
Smith further said Trump's latest attitude towards Trudeau isn't a new thing and he has "been kicking allies in the teeth his whole presidency".
Larry Kudlow, the White House economic adviser, also characterized Trudeau's remarks as a "betrayal".
How the Hill Reacted to the Trump-Kim Summit
He added that he hoped to withdraw United States troops from South Korea at some point - further undermining the long alliance. Trump first announced there would be "a signing" shortly after midday, during a stroll with Kim around the hotel grounds.

Another stumbling block was the part regarding climate change, where the United States didn't want to see any reference to the Paris Agreement, from which the Trump administration has withdrawn, The Star reported. Can't do it in person.
The communique - which had appeared to have papered over the cracks that surfaced at the summit - said the leaders of the US, Canada, Britain, France, Italy, Germany and Japan agreed on the need for "free, fair, and mutually beneficial trade" and the importance of fighting protectionism.
"When I got on to the plane, I think that Justin probably didn't know that Air Force One has about 20 televisions", Trump said. He had other things, bigger things, on his plate in Singapore. He reiterated his longstanding view that the United States has been taken advantage of in global trade, adding, "We're like the piggy bank that everybody's robbing, and that ends". "That will not stand".
"We finished the (G7) meeting and really everybody was happy".
"Don't blame Trump. It was Trudeau who started blasting Trump after he left, after the deals had been made".
Prime Minister Trudeau on the other hand, did not balk at the statements but instead remained professional and mature - which is to be expected from a leader of one of the most respected and democratic countries in the world. "This I've never seen before, nor has anyone else", Mulroney said. From promoting democracy and to fighting terrorism, "we're on the same page". The first issue involved the World Trade Organization.
