Nuclear Issues

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

Pakistan’s nuclear program and perceived nuclear security concerns have attracted global attention. The varying concerns range from the potential theft of nuclear weapons or materials to the unauthorized use of a nuclear device to terrorist groups taking control of the Pakistani government. The enduring debate, however, has oscillated between these doomsday scenarios and some optimistic considerations, where various quarters have shared their satisfaction over Pakistan’s nuclear security regime and its ability to deal with the emerging challenges. To address the evolving nature of these threats, Pakistan is constantly improving its nuclear security infrastructure. It has established a comprehensive legislative and institutional structure, nuclear security systems, and has also undertaken various international obligations. To further improve nuclear security perceptions, Pakistan should adopt a more transparent approach and learn from international best practices.

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

With rational decision-making, the likelihood of strategic nuclear exchange should be zero. But emotions can create uncertainty, contradicting the expectations of the rational cost-benefit assumptions undergirding deterrence theory.

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

The coronavirus pandemic has had a significant impact on the nuclear industry, complicating operations and altering the delivery of both safety and security. This has generated concerns over the ability of governments and industry to provide vital services, while also protecting against changing threats that have evolved to take advantage of the pandemic. Christopher Hobbs, Nickolas Roth and Daniel Salisbury examine the nuclear security community’s response to this challenge, exploring how the risk landscape has been changed by the pandemic and the efficacy of new security solutions.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.
