A new report by the Stockholm International Peace Research Institute (SIPRI) warns that the global nuclear risk is rising as nuclear-armed states increasingly move warheads from storage onto operational delivery systems. SIPRI says this shift increases the potential for rapid use and can heighten the danger of conflict, even though the total number of nuclear warheads worldwide is on a gradual decline. The institute links the change to current geopolitical rivalry and an emerging or expanding arms build-up that could halt or reverse earlier reductions. According to the reporting, the emphasis on keeping warheads on delivery systems reflects the growing role of nuclear weapons in national security policies and deterrence postures. Both outlets describe SIPRI’s assessment that while overall stockpiles decrease, changes in deployment and readiness can make the security environment more volatile. SIPRI’s warning therefore focuses less on the size of arsenals alone and more on how warheads are positioned and potentially made available for immediate deployment.
