Sudan, Iraq, Somalia, Zimbabwe, and Chad are the five most failed states in the world according to Foreign Policy's Failed State Index.
Variables include demographic pressures, refugees, group grievances, economy, human rights, and security. Liberia, Indonesia DR Congo, and Bosnia have made the most improvement since last year. Countries going down the tube are Niger, Equatorial Guinea, and Somalia. However, the Lebanon was the biggest collapse.
Failed states during Cold War were located in the "global south." Now as Central America is torn between globalization and failed Marxist policies after a decade of progress, most failed states form a cluster between middle Africa and Central Asia. TDAXP calls this the Afro-Islamic Gap. African and Arab kleptocracies are more concerned with personal gain while Islamists favor ummah (Islamist's version of globalization) versus neo-liberal globalization.
Now for a bit of cartographic criticism. Montenegro is shown as part of Serbia. It is time to update, Foreign Policy. Also, the decision to color shallow water differently from the ocean was a mistake. It has no purpose on a political map and it makes it difficult to tell what the status of Greece and other small countries are. (See, Catholicgauze did pay attention in cartography class way back)
