Again, the tariffs in question weren't just about immigration which you focused on. They are also about the drugs/fentanyl problem, potentially trying to protect U.S. industries, address trade imbalances, etc. As I said, multifaceted.
All Trump know is tariffs, he think tariffs alone will sloes drug/fentanyl problem. The tariffs does nothing to protect U.S. industries, that ship has sailed long time ago. All he does is disrupting existing supply chain, in hope some will return to US. He tried this on his first term, there is zero success.
Trade imbalance is even more funnier. The whole US is built on trade deficit which allow other countries to hold on US dollar as its reverse. The whole reason that US can sustain itself this long is because US dollar is being used widely and its status as reserve currency around the world. The moment you rip this apart, US dollar loss ground, your government won't last long.
