Post-NSS 2016 nuclear governance.
The Nuclear Security Summit (NSS) process was a diplomatic innovation that was intended to prop up global nuclear governance but which struggled to achieve progress on the fundamental issues of arms control, disarmament and non-proliferation due to high-level international deadlock. The process has formally ended with NSS 2016, leaving many issues unresolved.
The Marshall Islands' ICJ case against the nuclear-armed states is unlikely to accelerate disarmament efforts.
Doctrinal shifts favouring tactical nuclear weapons by Russia or Pakistan will form a significant setback for arms control.
Chinese concerns about triggering state collapse in North Korea will limit international pressure on Pyongyang's nuclear ambition.
