1. Afghanistan
Decades of warfare have left Afghanistan ravaged and deeply divided. The country managed to get invaded by both Soviet Union and the United States in a span of twenty odd years. In the meantime, years of war between various warlords and tribes have thoroughly destroyed any semblance of a civil society. It is no wonder then that Afghanistan is top of the list when it comes to 25 least tolerant countries in the world.
