BERLIN, GERMANY - MARCH 08: In this photo illustration bottles of American bourbon whiskey stand arranged at a whiskey shop on March 8, 2018 in Berlin, Germany. U.S. President Donald Trump has promised to authorize tariffs on imported steel and aluminum today and the European Commission has vowed to retaliate with tariffs on Levi's jeans, Kentucky bourbon and Harley-Davidson motorcycles.
