And the electricity, and the aluminum, and the potash...

It's really a big joke when Trump says the US doesn't need anything from Canada. It's actually the other way around. In Canada grow our own food so we won't go hungry, and we have lots of water and energy, we don't have any worry about getting cold in the winter. I can't think of anything we need from the US we couldn't also get from Europe or Asia. It would just cost a little more to ship it over the ocean. But really for most products The European and Asian made products are about the same price as the US made products.

I suppose the US midwest could retool their refineries and you could send oil by rail up from the Gulf of Mexico. But I don't think that'll be cheap. I guess you could get potash from further away too, though I hear there's some supply chain problems with getting fertilizer from the Middle East that might be a problem there.

The US has basically the lowest rate for recycling aluminum in the world. I suppose they could put a lot more effort to encourage recycling so they won't need as much aluminum.

But I somehow doubt there's a plan to do any of these things. Americans are just going to have to pay even higher prices for stuff.

He thought he could have it all. "Letting them see who's boss and they'll be begging to sign." The idea of Canada saying no probably didn't occur to him. "That's them just playing hard to get."

It's still unclear how far he's willing to push this but maybe fortifying the border would be a good precaution.

That's the fun part. As soon as Canada limits/taxes the export of energy the US will free us Canadians from the despotic rule of Ottawa.
