Israel's recent conflict with Iran, though deemed a short-term success, has prompted renewed concerns over Iran's nuclear ambitions and Israel's strategic responses. The article argues that Israel must rely on expert, visionary counsel to navigate the complex and evolving threats posed by Iran and its potential alliances with other nuclear-capable states. Central to Israel's security calculus is the question of whether to maintain its longstanding policy of nuclear ambiguity or shift toward more open nuclear signaling to deter adversaries. Multiple scenarios are explored, including the risks of escalation, the potential for unconventional warfare, and the importance of rational, science-based decision-making over reactive or ad hoc approaches. Ultimately, the piece underscores the necessity for Israel to continuously refine its deterrence strategies in the face of unpredictable regional dynamics and the ever-present possibility of nuclear conflict.
