This is one of seven essays in the roundtable Approaching Critical Mass: Asia’s Multipolar Nuclear Future.

One of the defining elements of the post–Cold War era has been the diffusion of power away from the two superpowers. This has occurred across a wide variety of measures, including nuclear weaponry. In particular, since the end of the Cold War, proliferation across states and increasing arsenal capabilities within some of them have characterized Asia’s international security affairs. Given the importance of nuclear weapons to the development and conduct of the Cold War, we should expect these changes in the post–Cold War era to be similarly important.

These changes have been the subject of significant scholarly analysis already. Dubbed the “second nuclear age” by eminent strategists Colin Grey and Paul Bracken, this epoch seems to pose new dangers and challenges. [1] Important debates have developed about the degree to which the most engaged dyad—India and Pakistan—is more dangerous than the dyads in the Cold War, to which nuclear weapons provided apparent stability. [2] Other studies have examined a broader range of countries facing this new environment. [3] A burgeoning quantitative literature surveys both Cold War and post–Cold War crises and dyads to evaluate a wide range of hypotheses about stability and coercive leverage. [4]
