North Korea and Turkmenistan are unchanging hells in which the population is cut off from the world and is subjected to propaganda worthy of a bygone age. And in Eritrea (173rd), which has come last for the second year running, President Issaias Afeworki and his small clan of paranoid nationalists continue to run Africa’s youngest country like a vast open prison.

The international community, including the European Union, endlessly repeats that the only solution continues to be “dialogue.” But dialogue has clearly had little success and even the most authoritarian governments are still able to ignore remonstrations without risking any repercussions other than the inconsequential displeasure of the occasional diplomat.
