"On Wednesday, President Donald Trump announced the US was imposing reciprocal tariffs on a small collection of Antarctic islands that are not inhabited by humans, as part of a global trade war aimed at asserting US dominance. The Heard and McDonald Islands, known for their populations of penguins and seabirds, can only be reached by sea.
Trump announced the countries now subject to tariffs in a Wednesday press conference, using a poster as a prop. Additional countries - including the Heard and McDonald Islands, which are, incidentally, not countries - were listed on sheets of paper distributed to reprters.
One of the sheets claims that the Heard and McDonald Islands currently charge a "Tariff to the U.S.A." of 10 percent, clarifying in tiny letters that this includes "currency manipulation and trade barriers." In return the sheet says that the US will charge "Discounted reciprocal tariffs" on the islands at a rate of 10 percent."
