The Least Peaceful Country

Globalpeace
Iraq claims the title for a fourth year:

Iraq received the worst score because of the continued political and social conflict in the country. Despite security improving in 2009 and the holding of provincial elections at the beginning of that year, there were still 4,645 Iraqis killed according to Iraq Body Count. In comparison, the Brookings Institution recorded 2,259 Afghans that died that year. The country also had a high number of displaced and refugees, which have not returned home. Military expenditures also increased last year because Iraqi forces were asked to do more with the U.S. beginning to withdraw. The growth of Prime Minister Nouri al-Maliki’s power was given mixed reviews because while he provided leadership, he also led to internal problems with other parties and the Kurds. Overall, the Institute thought that while 2009 was an improvement over previous years, the continued tensions and violence within Iraq justified putting it at the bottom of its list.
