What role does nuclear weapon capability play in international relations?

Nuclear weapon capability plays a significant role in international relations by acting as a deterrent against aggression from potential adversaries. The presence of nuclear weapons creates a strategic balance, discouraging adversaries from engaging in military conflict for fear of catastrophic consequences. This concept is often referred to as "Mutually Assured Destruction" (MAD), where both sides possess the ability to inflict unacceptable damage on each other, thereby maintaining a fragile peace through the fear of escalation.

In this context, the deterrent effect of nuclear weapons often leads to stability in international relations, as states are less likely to provoke a nuclear-armed opponent. Nations may calculate the risks of initiating conflict differently when nuclear capabilities are involved, leading to a cautious approach in diplomatic and military engagements. This dynamic significantly influences various global security strategies and alliances.

While other factors such as trade opportunities, bargaining chips in negotiations, and military spending do connect to nuclear capabilities, the deterrent function is fundamental and primarily shapes the interactions between nuclear states and their adversaries.
