Excerpt from "The Bomb: A New History"
Deterrence served as a form of nuclear defense during the Cold War — no one wanted to risk the threat of massive retaliation by initiating a nuclear attack. Nuclear weapons were owned by largely rational governments who understood the consequences of using them. Today we face quite a different set of threats, a mix of traditional nation-states that are deterred by the assurance of massive retaliation, rogue states that might not be so deterred, and international networks of terrorists that are willing to risk annihilation for the opportunity to inflict serious damage upon the United States.
