While North Korea’s recent nuclear tests significantly raised the level of fear in the United States, they were not a surprise. North Korea, long a nuclear state, is a dangerous nuclear proliferator that has shirked international commitments. Pyongyang issues highly aggressive rhetoric toward the United States and its regional neighbors on a regular basis; it flaunts its nuclear capability and threatens to use it, and tends to share nonconventional know-how and technologies. And herein lies a link to Tehran: as Iran also remains motivated in the nuclear realm despite the JCPOA, the direct implications of North Korea's activities for Iran's nuclear program must be under constant scrutiny. The indirect implications for dealing with Iran's nuclear motivation invoke the ability to rely on negotiations to stop a determined proliferator. The North Korean case of failed negotiations must be heeded when thinking about Iran.
