Wrong again, McFry. The Constitution nowhere forbids free, unrestricted trade with any foreign country. It only gives the feds choice but not the mandate to regulate such (Art I, Sec 8, Cl 3).
Wrong. The US Constitution doesn’t sanction or protect Free Trade with other nations in any way shape or form. It authorizes duties and tariffs on imports which is the opposite of Free Trade. The first law ever passed by the first congress was the tariff Act of 1789.
