Humanitarian Aid Still Needed in Nuclear-Pariah North Korea

In the 1990's, famine killed 2 million people in North Korea; Kim Jong Il appealed for assistance. Last year, he ordered donors to leave the country or scale back their programs. This year, the country faces a cold winter and likely food shortages, just as it's facing sanctions for testing a nuclear bomb. South Korea and China have both reduced aid since the test, and the US has cut its donations to the UN's World Food Program since Kim Jong Il cut back its mission earlier this year. What are the humanitarian prospects?
