Conclusion
This chapter summarizes key findings in the proponents of the “theory of the nuclear revolution,” which contend that nuclear weapons are transformative because they greatly reduce the need for countries to engage in intense security competition. It emphasizes that although nuclear weapons are the greatest tools of deterrence ever created, they do not automatically confer national security benefits on their owners, much less guarantee enduring safety from foreign threats. The chapter looks into the unfortunate reality of international politics in the shadow of nuclear weapons, in which countries must still pay close attention to the balance of power, search for ways to change the balance when they find themselves at a disadvantage and contemplate and plan for war in order to protect vital national interests. It explains how fears that tragically drove international politics for centuries still exist and how those fears are justified. The nuclear age remains an age of power politics.
