Leave it to Fox News’s Shepard Smith to add a peculiar twist to the burgeoning war of words between Donald J. Trump and Justin Trudeau.

The news anchor wondered out loud whether we need to build a wall along our northern border with Canada, to complement the wall Trump wants to build along our southern border with Mexico.

Trump left the G-7 summit in Quebec after leveling threats against our major trading partners. He and the Canadian prime minister got into a particularly angry exchange, with Trump accusing Trudeau of double-crossing him after he left the summit.

Trudeau responded with threats of retaliation against the United States over the tariffs Trump has leveled against Canadian steel and aluminum. A Trump economic adviser, Peter Navarro, said there is a “special place in hell” for anyone who stabs the president “in the back.”

As the Daily Beast reported: “Our biggest trading partner in all the world, our best friend from way back in World War II and every time in between, Canada” Smith added, laughing for a moment before dropping this suggestion: “Maybe we need a Northern wall.”

Do you get my drift here?

Trump announced his presidential campaign by declaring that Mexico is “sending rapists, murderers and drug dealers” into our country. He said he would wall off the country from Mexico and make the Mexican government pay for it.

Is there another such threat awaiting the Canadians now if Trump and Trudeau keep exchanging heated insults across the world’s longest unsecured border?
