North Korea - After the Korean War, Kim Il-sung introduced the personal philosophy of Juche, or self-reliance, which became a guiding light for North Korea's development. Kim Il-sung's son, Kim Jong-il, is now head of state, but the post of president has been assigned 'eternally' to his late father. Decades of this rigid state-controlled system have led to stagnation and a leadership dependent on the cult of personality. Aid agencies have estimated that up to two million people have died since the mid-1990s because of acute food shortages caused by natural disasters and economic mismanagement. The country relies on foreign aid to feed millions of its people. The totalitarian state also stands accused of systematic human rights abuses. Reports of torture, public executions, slave labour, and forced abortions and infanticides in prison camps have emerged. A US-based rights group has estimated that there are up to 200,000 political prisoners in North Korea.
