"[The author] has spent her career studying civil conflict in places like Iraq and Sri Lanka, but now she has become increasingly worried about her own country. Perhaps surprisingly, both autocracies and healthy democracies are largely immune from civil war; it's the countries in the middle ground that are most vulnerable. And this is where more and more countries, including the United States, are finding themselves today. Over the last two decades, the number of active civil wars around the world has almost doubled. [The author] reveals the warning signs--where wars tend to start, who initiates them, what triggers them--and why some countries tip over into conflict while others remain stable. Drawing on . . . international research and lessons from over twenty countries, [she] identifies the . . . risk factors, from democratic backsliding to factionalization and the politics of resentment"--Provided by publisher.
