For America, civil wars elsewhere in the world might seem like somebody else’s problem. But in reality we’re very likely to end up playing a role: Most civil wars don’t end without foreign intervention, and America is the lone global superpower, with huge sway at the United Nations. Christia suggests that Washington would do well to acknowledge early on that it will end up intervening in some form in any civil war that threatens a strategic interest. That doesn’t necessarily mean boots on the ground, but it means active funding of factions and shaping of the alliances that are doing the fighting. In a war like Syria’s, that means the United States has wasted precious time on the sidelines.
Despite her sustained look at the worst of human conflict, Christia says she considers herself an optimist: People spend most of their history peacefully coexisting with different groups, and only a tiny portion of the time fighting. And once civil wars do break out, the empirical evidence shows that hatreds aren’t eternal. “If identities mattered so much,” she says, “you wouldn’t see so much shifting around.”
