Don't Count on a North Korean Nuclear Deal (Denny Roy, The National Interest)

The persistent North Korea nuclear weapons crisis is generating heightened fear among the countries targeted by Pyongyang for hostile signaling, including the United States. Washington reacted strongly to the DPRK’s fourth nuclear test in January, leading the effort in the United Nations Security Council to impose a new set of sanctions that observers say is tougher than usual. Nevertheless, it is uncertain whether China will fully enforce these sanctions, and indeed whether any sanctions short of a total international economic embargo (to which China is not agreeable) would force Pyongyang to abandon its nuclear weapons and intercontinental ballistic missile (ICBM) programs.
