Canada

No, because Canada's economy will collapse long before the US economy if each side just keeps increasing tariffs. What Canada needs to do is make things cheaper for Canadians, not more expensive.

Take any law related to US intellectual property and decriminalize that.

Violating the copyright on Hollywood movies? Go for it. No charge.

Something you want to do is covered by a patent held by an American? Do it, you won't be prosecuted.

Want to bypass DRM on a tractor, a printer, an iPhone, sell or give away tools to allow anybody else to do it? Feel free.

The biggest advantage of this approach is that if the US did the same thing with respect to Canadian IP, they'd have so much less to work with. The US has geared its economy towards producing IP, and then used trade deals to demand that other countries respect that IP or the US will put tariffs on their stuff. Well, clearly the US isn't holding up its end of that bargain, so fuck 'em.
