“I know why, and it’s because my president is threatening to annex your country.”
It’s far more than that. The Trump administration is lawless, ignoring and defying the courts, and trampling on the constitution. My son’s school just cancelled a long planned trip to New York City because of the very real risk that one of more of the children in the trip might be held, handcuffed, and thrown in ICE detention for days or weeks. Under the current authoritarian regime it is unsafe for anyone to travel to the US.
Yeah, if Canadians had the character to withhold their vacation dollars over the unacceptable behaviour of the US government, they would have stopped going there 20 years ago. The only difference is that now you risk being summarily thrown in a gulag even if you don’t look stereotypically middle-eastern.
None of that unquestionable behaviour was their President literally stating that we should be annexed, however.
