President Donald Trump on Thursday night signed an executive order applying blanket tariffs to scores of countries. In announcing tariffs ranging from 10% to 41% levied against around 70 countries, Trump began a new chapter in a volatile, months-long saga that reached a fever pitch over the last couple weeks, during which he also announced hundreds of billions of dollars worth of so-called trade deals with the United Kingdom, Japan, Indonesia, the European Union, and South Korea, among others.
