BERN, SWITZERLANDAngered by rising international tariffs against his nation, Swiss president Gunter Klima threatened a worldwide Ricola embargo Tuesday. 'If these unfair tariffs are not lifted,' Klima said, 'we will have no choice but to withhold our natural Alpine-herb throat lozenges, causing billions of throats across the globe to go tragically unsoothed.' An estimated 2.1 billion people rely on Swiss menthol for their throat-calming needs.
