Post World Wars most those countries did not fair well . Military rule , dictators , soviet era stuff , more conflicts etc These kind of rulers and conflicts tend to fuck up countries development and economy .

Thousands languished in prison for many years or were sent into exile on the islands of Gyaros and Makronisos .
