Every year, Foreign Policy publishes their Fragile State Index (although it was previously called the Failed State Index). This is precisely what it sounds like: an analysis of the stability of nations around the world.
For anyone interested or concerned with global politics, this is must-read material. It’s an important view of where conflict and strife not only currently exists, but where it could rise and overwhelm nations and their neighbors. Beyond the numerical index, they always have editorial surrounding the rankings to give useful insight.
