Trump’s war on Canada a pitiful own goal

This summer, America played host to one of the biggest international events on the planet, the World Cup, drawing millions of foreigners to our cities and towns, our stadiums and our national parks, where many of them had never been before.

The consensus was, America is awesome — visitors from Bolivia, Scotland, Uzbekistan, and everywhere in between marveled at the sheer size of our great nation, the diversity of our topography, the deliciousness of our foodstuffs, and, perhaps most importantly, the kindness of our people. (Not to mention, our eighth wonder of the world — Buc-ee’s.)

What a difference a month makes.

Despite our friends in far-flung places singing our praises, now, to hear our closest neighbors tell it, America is nothing but a “ bully” and a “ thug.”

After trade negotiations with Canada collapsed this week, and President Trump announced a whopping 50% tariffs on $20 billion worth of Canadian goods — including Canadian whiskey and hockey sticks — it’s no surprise our friends to the north are less than pleased with their downstairs neighbors.

In our defense, not all of us are responsible for electing the bully and thug in question — and if polls are any indication, most Americans agree with Canada that Trump is doing a terrible job. But still, it’s hard to hear.

Especially since we love Canadians, and we very much want them to love us back.

But after spending years threatening to invade Canada and make it the “51st state,” and mocking its leaders with petty nicknames and school yard insults, Trump may have finally put Canadians’ famous politeness to the test.

“You’re at war when you’re attacked, and we got attacked,” said Prime Minister Mark Carney. “We’re going to hit back.”

Manitoba Premier Wab Kinew called Trump “erratic,” “irresponsible,” and “a bad person” who was “not to be trusted.”

And Ontario Premier Doug Ford wasn’t nearly as nice, calling Trump the “king of bankruptcies,” and telling him to “Kiss my ass.”

Again, these are our friends talking!

But their righteous indignation is justified — we are in the midst of an unpopular war that we can’t seem to end, our economy is in the toilet, we’re banning books, deporting children with cancer, shooting unarmed protesters, spreading measles, and covering up for one of our most notorious sex offenders. And we have the audacity to attack our nice and normal friends?

But it’s not just an issue of bad manners. Americans have long been accused of that.

It may be an election issue now.

States like Michigan, Maine, Alaska and Ohio, all of which border Canada and are important trade partners, also have another thing in common: highly competitive Senate races.

And despite all but Maine voting for Trump in the last election, Cook Political Report lists all four as a toss-up.

The Canada trade issue is real these voters; for auto workers in Michigan who rely on Canadian aluminum and steel; for 95% of Mainers who rely on Canada for home heating; for Ohioans who use Canadian metals and machinery; for Alaskans who need Canadian crude.

So Democratic Senate candidates like Abdul El-Sayed in Michigan and Mary Peltola in Alaska have yet another important talking point to add to their reservoirs — that Trump’s dumb trade war, much like his dumb actual war, is going to make voters’ lives worse.

Add it to the pile — a majority of voters already believe they are worse off under Trump, and this won’t help.

With fewer than 70 days until the midterm elections, the imprudence of picking a fight with important allies — who now seem prepared to unleash retaliatory economic pain on Americans in competitive states hardly seems debatable.

But Trump seems hell bent on totally destroying whatever good will we still had left on the world stage.

Talk about an own goal.
