On Wednesday, Brookings Senior Fellow Robert Kagan sat down with Susan Glasser of The New Yorker to discuss Kagan's new book The Jungle Grows Back: America and Our Imperiled World. In the book, Kagan argues that, like the jungle that keeps growing back, dangerous global actors, when left unchecked, will create chaos. Kagan and Glasser discussed whether the American public tends to support foreign policy that focuses on international withdrawal or unilateral intervention, whether the Trump foreign policy will enable faster growth of dangerous actors, and whether the America of 2018 has parallels to the U.S. in the 1920s or 1930s.
