WASHINGTON — A gobsmacked planet is wondering what’s next from President Donald Trump on the tariff spree he’s set in zigzag motion. In recent weeks, Trump has announced punishing tariffs against allies and adversaries alike, selectively paused and imposed them, doubled and then halved some, and warned late in the week that he’ll tax European wine and spirits a stratospheric 200% if the European Union doesn’t drop a 50% tariff on U.S. whiskey. His ultimate stated goal is clear: to revive American manufacturing and win compromises along the way. But people and nations whose fortunes rise and fall on trade are trying to divine a method to his machinations. So far, he’s spurred fears about slower growth and higher inflation that are dragging down the stock market and consumer confidence. “His tariff policy is erratic,” Robert Halver, at Germany’s Baader Bank, said. “So, there is no planning certainty at all.”
