Nuclear deterrence is fundamentally concerned with preventing attacks through the fear of retaliation. The concept is based on the idea that the possession of nuclear weapons creates a significant deterrent effect; adversaries are less likely to initiate aggression if they believe that the response to an attack would be overwhelmingly destructive. This principle hinges on the notion of mutually assured destruction—if both sides have credible nuclear capabilities, the catastrophic consequences associated with a nuclear exchange serve to maintain a tense but stable peace.

In this framework, the threat of retaliation plays a crucial role; it is not just the existence of nuclear weapons that deters, but rather the perception that they will be used in response to an attack. This strategic rationale has shaped much of the Cold War dynamics and continues to influence contemporary security environments among nuclear-capable states.

The other choices, while relevant to broader discussions around security and international relations, do not encapsulate the primary concern of nuclear deterrence. Encouraging military alliances, promoting disarmament treaties, and facilitating open negotiations all pertain to different strategies and goals in international politics that may coexist alongside deterrence strategies but do not directly address its core objective of preventing conflict through the threat of retaliation.
