Clandestine tests by rogue states might go…
Undetected.
Safety and reliability of existing weapons can be verified how?Without testing and usingcomputer simulations Instead.
International monitoring system now in place that would detect any secretly- conducted tests. Treaty also allows for inspectionsto verify compliance.
CTBT provides forfor creation ofglobal networkof monitoringstations andlaboratoriesmeantto detectnuclearexplosions.
