The article examines the legality of classifying the current crisis involving Iran as a preventive attack, emphasizing that international law permits states to act defensively against existential threats. It references Article 51 of the United Nations Charter, which upholds the inherent right to self-defense in the face of an imminent armed attack. The focus of the discussion is not on the existence of the right to self-defense, but rather on the circumstances that necessitate its invocation, with criteria such as necessity and proportionality being crucial to the legal framework.

The author argues that the Iranian regime's history since 1979 complicates the argument that the threat it poses is abstract. The regime's actions over the decades have demonstrated a consistent pattern of behavior which may justify a state's defensive measures. Discussing the implications of this legal and ethical argument, the article highlights that any action taken in self-defense should aim to neutralize the threat, rather than simply punish the aggressor, aligning with international legal standards.

Overall, the analysis encourages a deeper examination of the actions of states facing existential risks, particularly in a volatile geopolitical environment, where preemptive actions may be deemed necessary under certain conditions. This view challenges conventional interpretations of international law and underscores the importance of context in determining the legitimacy of self-defense claims.
