So what’s happening, and why should you care? In a world increasingly inhabited by the homeless and displaced, Chad is the worst-case scenario. Nearly half a million refugees make this one of the most desperate and volatile countries in the world. Here we see the enormous human toll of the ongoing conflict in Darfur, which has expanded into proxy wars between Chad, Sudan and the Central African Republic. Refugees from all three countries have sought safety in Chad. But Chad is far from safe, and even the presence of thousands of French and E.U. troops cannot guarantee the country’s integrity. Chad is bad off. But Chad could get much much worse. We should care not just because Chad is a major oil exporter, but because this crisis could spread throughout central Africa, affecting millions.
