Ian Bremmer, author of "Every Nation for Itself" and "Superpower," now takes on the populist backlash against globalism with a stark warning about where this trend might be headed in his new book, "Us vs. Them: The Failure of Globalism," out April 24.

Ian's insight: It’s not just Europe and America. Technological and economic changes, the historic flow of people across borders, and public demand for protection have empowered a whole new class of politicians with a talent for pitting one group against another.
