One of those evenings when you realize that there is more that needs to be addressed than just economic systems.

From the NYT:

North Korea said it had successfully conducted a nuclear test on Monday, raising the explosive power and level of control of its nuclear device to a new level, its state media said.

“We have successfully conducted another nuclear test on May 25 as part of the republic’s measures to strengthen its nuclear deterrent,” the North’s official KCNA news agency said.

South Korea’s Yonhap news agency also quoted a ruling party official as saying that a test was conducted.

YTN Television quoted the South Korean weather agency as saying it detected a tremor indicating a test at 0054 GMT.
