Trump is back to his old foreign policy ploys. But he should leave Canada be.
This
 all started when Trump threatened to add 25 percent tariffs to all 
goods coming from Canada. Then, according to Fox News, Justin Trudeau 
objected on the grounds that this idea was stupid, so Trump said that if
 Canada didn’t like it, it could become our 51st state. And then there 
was “nervous laughter.”
Yup, the Trump times are back. Once again, our foreign policy is: Please Tell Me This Is a Joke.
While
 I enjoyed the anxious flittering  of Trump’s posse that followed,  
(“Brilliant idea, sir! But have you considered that  if we added Canada 
as a state, it would be too liberal?” “That’s fine. We will make it two 
states!”), I, for one, am not afraid to say: I don’t think annexing 
Canada is a good idea.
You know, we have norms for a reason, and I think the norm of not invading our northern neighbor is a good one.  Also, I
 remember the War of 1812 — well, not personally, but I read about it — 
and what I took from it is that we should not get into unprovoked fights
 with Canada, at least not if we like the way our White House is 
currently decorated.
It
 is not just the idea of invading Canada that bothers me, although it 
does, especially since winter is coming. Do we remember what happened to
 Napoleon when winter arrived and he tried to invade a little place I 
like to call “Europe’s Canada”? It didn’t go well for him! And Russia 
did not even have hostile, dedicated geese, the way Canada does. Have 
you ever been on bad terms with a Canada goose? It isn’t safe. They will
 do to our whole country what they have already done to our country’s 
golf courses.
I
 know that Donald Trump thinks that precedents like that don’t apply to 
him because he is taller, or tanner, or something, or that he is immune 
to history because he refuses to read and just gets all his facts from 
Steve Bannon whispering into his ear in a sinister fashion, but that’s 
not how history works.
I
 also think that, once we annex Canada, we would have no idea what to do
 with it. We’d be out of our depth in so many ways. First, it would make
 the country a weird shape and ruin all the maps. Also Alaska, which 
likes its space, would be stressed out to find itself suddenly 
coterminous with the rest of the United States. We should leave Alaska 
be; it’s full of bears.
Third, we would have to change the flag, and  altering the flag in any way would distress and anger Martha-Ann Alito. I do not want to get on her bad side. Every time that happens, we lose a right.
Fourth,
 everyone in Canada expects actual health care and a social safety net 
that we are ill-equipped to provide. Fifth, if Toronto actually became 
part of this country, we would have to stop telling moviegoers that it 
was New York City and filming everything there. Sixth, it would 
introduce a confusing new type of bagel to the bagel ecosystem that 
competes against our native bagels. Finally, perhaps most ominously,  it
 would remove any last smidgen of doubt that Ted Cruz is eligible to run
 for president.
I
 know that there would be some upsides. Poutine! Mounties! A Northwest 
passage! Everyone who speaks high-school-level French would perk up at 
the thought of Quebec becoming a whole Francophone addition to our 
north. (Unfortunately, they speak Québécois French, so our French would 
be completely useless there.)
And,
 yes, we would gain Celine Dion. But we would also gain Drake. Also, 
expanding in this sudden, aggressive way might make Russia feel nervous 
that it was next.
But
 fundamentally, I think this sets a bad precedent. We cannot just go 
around threatening to annex every country that says Donald Trump’s 
economic ideas are bad. If we do that, we will be at war with the whole 
world: not just trade war, actual war. I just don’t think it’s a good 
idea.
