Gideon Rachman’s Easternization, his new survey of a transformed Asia, admirably does what so little writing on foreign affairs attempts. It treats with equal facility economics, geopolitics, security, enough history for needed background, official thinking, and public attitudes. Rachman, chief foreign affairs columnist for the Financial Times, has an eye for the telling statistic and for the memorable detail that makes it stick. He packs an enormous amount of information into a short book and opens windows of understanding for nonexperts onto this immensely important three fifths of humanity. And while not directly concerned with the new American administration, the story he tells shows well why Donald Trump’s foreign policies could end so badly for the United States and for the world.
