US President Donald Trump's attempts to jettison the Iran nuclear deal will, in the eyes of many observers, send a dangerous message to the international community, and to North Korea in particular.

For months now, the international community has argued that Iran is fulfiling its obligations under the 2015 Joint Comprehensive Plan of Action, known as the JCPOA. Trump's campaign promise to withdraw from the accord, however, comes at a time when his administration is already struggling with how to contain the nuclear ambitions of Pyongyang.
