The most destructive tools ever invented have never been used in war since 1945. Scholars usually explain this with the concept of deterrence. But this reasoning has a problem. It says that weapons prevent war because they haven’t been used. Yet that non-use is then taken as proof that deterrence works. What gets left out is the actual reason why simply possessing these weapons makes people not use them.
Kenneth Waltz, a leading thinker in deterrence theory, wrote in 2012 that letting Iran build such weapons might actually lead to more peace. His logic makes sense in a world where nations act based on calculated self-interest. But his argument depends on an idea that needs closer examination: that these weapons are basically tools for warfare, whose political power comes from the real risk of their use. This assumption, however, is questionable. The truth is, these weapons serve a different role. They function more as statements of power than as traditional weapons.
The Declaration of Sovereignty
The Legal Exception for Nuclear Use
All nuclear policies include a clear statement: if a state faces an extreme threat to its existence, it can use these weapons without being bound by international law or the rules of war. Carl Schmitt, in his work on political theory, described sovereignty as the ability to decide when the usual rules of society no longer apply. He wrote that the sovereign is the one who decides when an emergency exists. A state’s nuclear weapons are the constant physical form of this declaration. They don’t need to be fired to be effective. Their presence alone is the ongoing message that this state is among those who can end the world if it chooses.
These weapons work at a deeper level than just military strategy. They don’t make nuclear states stronger in the same way as non-nuclear states. Instead, they change them entirely. J. L. Austin, a philosopher, made a distinction between language that simply reports something and language that creates something. For example, when a judge sentences someone, the words don’t just describe a punishment. The words themselves form the punishment. When a state gets these weapons, it doesn’t just declare power. It actually transforms its sovereign identity through that declaration. The statement is the reality.
Jean Baudrillard, who analyzed nuclear deterrence, pointed out that these weapons have a unique dynamic. Their only purpose is to be unused. The second they are used, the whole idea of deterrence breaks down. Their strength is entirely based on the fact that they exist without ever being activated. They are a sign of potential destruction, not actual destruction. The system built around them has always revolved around their symbolic role rather than their military function.
The Flawed Game of Strategy
Deterrence theory has spent decades treating these weapons like normal military tools in a game of strategy. But the real evidence shows that this perspective is flawed. Pakistan responded eleven days later with its own tests. Neither action changed the actual military balance between the two countries. India had had the capability to build such weapons since 1974. Pakistan had the potential to do so since the late 1980s. But both states chose to make their nuclear status public. What was declared was not a new military threat. It was a political performance. It was the official recognition that both now belonged to the class of nuclear-armed nations.
The global reaction focused not on military capability but on the significance of the declaration. Sanctions, diplomatic pressure, and UN meetings followed. This response showed that the world viewed the nuclearization of the region as a political act, not a purely military one. After these tests, the Kargil War broke out, marking the first conventional conflict between two nuclear states. Waltz’s theory suggested that having these weapons would stop wars before they begin. Kargil showed the opposite. What these weapons actually did was not prevent conflict. They created boundaries within which conflict could occur.
The Political Power of Nuclear Presence
The logic of these weapons operates on political identity, not just strategic calculations. Their value lies not in their use but in their presence. They are not weapons in the way that tanks or missiles are. They are declarations that a state holds the ultimate form of sovereignty. In the 21st century, with many states vying for power, this understanding is more important than ever. The real challenge is to see beyond the illusion of deterrence and into the deeper meaning of what it means to possess the ability to end the world.
