Trump's apparent threat to end US trade deals with top allies came as he feuded with French President Emmanuel Macron, Canadian Prime Minister Justin Trudeau and other leaders over the trade war he instigated late last month. "As Canadians, we're polite, we're reasonable, but also we will not be pushed around", he said.
U.S. President Donald Trump's Twitter tirade against Prime Minister Justin Trudeau following the G7 is sparking promises of support from some of Trudeau's political rivals as well as calls for calm from foreign diplomats and experts.
Earlier in the day, Trump had said there should be "tariff free" trade between the G-7 nations, though he did not elaborate on how or whether the USA would reduce barriers.
Kudlow says Trudeau's actions were a "sophomoric play" and says the prime minister stabbed his United States allies in the back, which he argues did a great disservice to the whole G7.
"This weekend, certainly if you care about America's place in the world, had to be one of the most concerning, certainly, and I'll just say the most depressing, in Donald Trump's year-and-a-half in office", Scarborough said on "Morning Joe" while introducing James Stavridis, chief worldwide security and diplomacy analyst for NBC News and MSNBC.

"He really kind of stabbed us in the back", Kudlow said.
"The president will continue to say what he says", he said of Trump.
"It was a betrayal", Kudlow said on CNN's "State of the Union".
McCain's message came after President Donald Trump withdrew the USA endorsement of a joint statement from the G-7 summit on trade and tariffs.
On Twitter, Trump complained that Trudeau had criticized USA trade policy - specifically US tariffs on Canadian metals - after the Canadian premier had "acted so meek and mild" in their one-on-one meeting.
Presumably, as Toronto Star reporter Daniel Dale pointed out on Twitter, Kudlow was upset that Trudeau's comments could hurt Trump's chances of impressing Kim Jong Un ahead of his meeting with the North Korean dictator in Singapore this week. "I did suggest it and people were - I guess they're going to go back to the drawing board and check it out".
