Trump’s trade war bluster over China is rattling the world

The sharp rise of the Dow Jones Industrial Average since Donald Trump’s election as president in November 2016 is something he and his supporters often cite to show how he has helped the economy — and how, despite his divisive style, Trump’s tax cuts and regulation reductions have been good for America. But the president’s bluster about trade wars — “I am a Tariff Man” — and the important U.S.-China relationship has so far fueled only chaos. Consider this week. The Dow dropped 799 points Tuesday then had a wilder day on Thursday, closing down 79 points after falling as much as 784 points.
