Wall Street Journal on North Korea options:
Withholding food aid to bring down a government would normally be unethical, but North Korea is an exceptional case. Past aid proved to be a mistake as it perpetuated one of the most evil regimes in history. The U.N. says some 40% of the population is undernourished, even as the Kims continue to spend huge sums on weapons. Ending the North Korean state as quickly as possible is the most humane course.
