What this is

Confirmed use of a chemical weapon, biological agent, radiological device, or nuclear weapon in a kinetic event — state use (Syria sarin 2013, Novichok 2018, 2020), non-state use (Tokyo sarin 1995, Boston anthrax 2001), or state-sponsored assassination. F-CT-8 τ-discharge at the WMD-threshold grain. Each confirmed use erodes the Geneva + NPT + CWC norm. Nuclear use would be regime-change for the whole international order.
