The Samson Option stands in contrast to doctrines embraced by other nuclear powers, such as “Mutually Assured Destruction” (MAD). Developed during the Cold War, MAD posits that nuclear powers like the United States and the Soviet Union could deter each other from ever using nuclear weapons through the threat of retaliatory strikes—that is, if one nuked the other, the other would nuke back, meaning neither would survive. Unlike MAD, Israel’s Samson Option specifically threatens its non-nuclear opponents.
