It is a good thing canadians are so nice. Dropping US alcohol is a tiny thing compared to some of the weapons canada might deploy. Look at all the back-and-forth deals in recent years and you will see an exemption for oil and potash. Think gas prices are high now? See what happens if canada starts shipping less crude. Think food prices are high? See what happens when there is no fertilizer because canada has restricted potash exports. And what will make Musk's head explode: canada is starting to allow cheap chinese EVs into north america. Canadians will be driving them around the US very soon.
> US mines produce roughly 500,000 metric tons of potash per year, only about 8 percent of the 5.9 million metric tons of apparent annual US consumption. The remaining demand is met through imports, producing a net import reliance of about 92 percent. Reflecting the high concentration of global potash production, most of that supply comes from Canada (79 percent), with smaller volumes from Russia (12 percent) and other producers (9 percent) including Israel.
