Nuclear Issues

As Israel begins its ground invasion in Gaza, Niall Ferguson and Jay Mens on the hard strategic decisions facing the West.

As the Biden administration and Congress struggle to get their heads around the challenge posed by China today, they should reflect on lessons learned in America’s success in winning the Cold War with the Soviet Union. Just because fundamental and irresolvable differences in values and interests compel the United States and China to be formidable rivals does not mean a hot war is a viable option.

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.

Graham Allison is interviewed about U.S.-China relations by the Global Macro Research Team for a Goldman Sachs publication.

Should a nuclear war “never be unleashed?” Can nuclear weapons be used to “ensure the safety of the Russian people?” Both, according to President Vladimir Putin, who has become fond of alternating assertive and conciliatory tones in his messaging on the conditions for the use of nuclear arms. Such discourse comes as he tries to coerce Ukraine into accepting his land grabs and prevent the West from escalating assistance to Kyiv, all while keeping China content.

A quarter-century ago, China conducted what it called “missile tests” bracketing the island of Taiwan to deter it from a move toward independence by demonstrating that China could cut Taiwan’s ocean lifelines. In response, in a show of superiority that forced China to back down, the United States deployed two aircraft carriers to Taiwan’s adjacent waters. If China were to repeat the same missile tests today, it is highly unlikely that the United States would respond as it did in 1996. If U.S. carriers moved that close to the Chinese mainland now, they could be sunk by the DF-21 and DF-26 missiles that China has since developed and deployed. This article presents three major theses concerning the military rivalry between China and the United States in this century.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

Carpenter and Montgomery replicate a key question from Sagan and Valentino’s landmark survey of U.S. attitudes toward the laws of war and introduce variations into Sagan and Valentino’s experiment. The findings reveal Americans’ strong belief that targeting civilians is wrong, and that a majority would likely oppose such action in real life.

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.

The 2018 National Defense Strategy (NDS) is predicated on a single organizing principle: America’s military pre-eminence is rapidly eroding. This is not a new concept. For years, experts have warned that the economic and technological advancements of U.S. adversaries, coupled with the 2008 financial crisis and America’s focus on peripheral conflicts, have caused a decline in America’s military dominance. 

In this context, the advances of near-peer competitors such as China and Russia have created plausible “theories of victory” in potential conflicts across Eastern Europe and East Asia. Competitors’ unaddressed improvements in strategic innovation, economic investment, and dual-use technology increases the risk of conflict and strains the U.S. alliance system. It is urgent that the United States reestablish and maintain credible deterrents against these near-peer competitors. After decades of focusing on post-Cold War ‘shaping’ operations, the American military needs to reinvigorate for full spectrum great power competition.

This report is intended as a blueprint on how to begin that process from graduate students at the Belfer Center for Science and International Affairs at Harvard University. Contained inside are 12 memorandums. Each provides a high-level overview and specific recommendations on a key issue of American defense policy.
