由于达尔富尔危机，《外交政策》(Foreign Policy)杂志与和平基金会(Fund for Peace)共同制作的“2008失败国家指数”(2008 Failed States Index)将苏丹列为世界第二最不稳定国家。
SOMALIA TOPS LIST OF WORLD'S MOST UNSTABLE NATIONS
Somalia has for the first time been ranked as the most unstable country in the world, while Israel has fallen into the ranks of the 60 weakest states, according to an annual assessment of the world's most troubled nations.
The 2008 Failed States Index, which is produced by Foreign Policy magazine and the Fund for Peace, also argues that Sudan, with its crisis in Darfur, is the world's second most unstable country.
Sudan is closely followed by Zimbabwe. The country's economic crisis and political turmoil have triggered the slide in this year's index.
Israel's low score – it ranks 58th on the list – reflects, in the words of the report, “deteriorating security in the West Bank, the country's sharp economic disparities, political stalemates, ongoing violence, and its failure to fully integrate its Arab minority”.
According to this year's index, seven of the top 10 most unstable countries are in sub-Saharan Africa. With Chad taking fourth place for political instability, sub- Saharan states occupy four of the top five places in the index.
Fifth place goes to Iraq. This is an improvement on last year, when it was ranked as the second most unstable country. The US military surge has been a key factor in the country's performance in the index this year.
However, Iraq's gains do not reflect long-term, fundamental changes, according to the report's authors. “The desperate predicament of 4m refugees at home and abroad, the abysmal state of public services, and the discord among sectarian factions have shown no real improvement,” according to the index.
