• Describe the relationship between deterrence and the concept of Mutually Assured Destruction (MAD) in the context of foreign policy.
  • Mutually Assured Destruction (MAD) is a specific doctrine of deterrence in which the threat of overwhelming retaliation deters nuclear-armed adversaries from attacking, as it would lead to the destruction of both sides. MAD is a key concept in the context of foreign policy, as it represents a strategy of deterrence that relies on the ability to inflict unacceptable damage on an adversary, even in the event of a first strike. The credibility of this threat is essential for deterrence to be effective, as potential aggressors must believe that the retaliation will indeed be carried out, even at the cost of mutual annihilation.
• Analyze how the concept of deterrence has evolved over time and how it has influenced the development of different approaches to foreign policy.
  • The concept of deterrence has evolved significantly over time, influencing the development of various approaches to foreign policy. Initially, deterrence was primarily focused on the nuclear domain, with the doctrine of Mutually Assured Destruction (MAD) serving as a key strategy. However, as the international security landscape has changed, the application of deterrence has expanded to include conventional military capabilities and other non-military tools, such as economic sanctions and diplomatic pressure. Deterrence theory has also evolved, with scholars and policymakers exploring different models and strategies to enhance the credibility and effectiveness of deterrent threats. These developments have, in turn, shaped the formulation of foreign policy, as governments seek to design and implement deterrence strategies that align with their broader national security objectives and the changing geopolitical realities.
