Nuclear weapons are uniquely capable of threatening entire countries’ existences, but not all nuclear weapons possessors are equally capable of posing such threats. This article explores the existential threats that nuclear weapons possessors pose with a new, empirically based metric called the Nuclear Annihilation Threat (NAT) Index. Using the NAT Index, we comparatively analyze the existential threats and vulnerabilities that nuclear-armed states face from one another. In particular, we apply these insights to gain a better understanding of the nuclear security threats and vulnerabilities of the United States and Israel and explore the implications of Iran going nuclear for both countries.
