Commercial international port terminals owned and operated by Chinese firms provide dual-use capabilities to the People's Liberation Army during peacetime. They enable China to project power into critical regions worldwide by providing military logistics and intelligence networks.

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.

David Kilcullen, a professor at the University of New South Wales, contributes to the debate of  whether contemporary great-power resurgence constitutes a second bi-polar competition by assessing resurging state and non-state competitors and the challenges they pose to the United States–led world order. While the emerging security environment might not be a new Cold War, Kilcullen contends it may be more dangerous than in the past.

China has the world’s largest army. Russia wields the most tanks. America owns the fanciest satellites. But who has the most cyber-power? A new National Cyber Power Index by the Belfer Centre at Harvard University ranks 30 countries on their level of ambition and capability. Offensive cyber-power—the ability to do harm in or through computer networks—is one measure. But so too are the strength of a country’s defences, the sophistication of its cyber-security industry and its ability to spread and counter propaganda.

As conventional wisdom goes, experts tend to rank the U.S ahead of China, U.K., Iran, North Korea, Russia, in terms of how strong it is when it comes to cyberspace. But a new study from Harvard University’s Belfer Center shows that China has closed the gap on the U.S. in three key categories: surveillance, cyber defense, and its efforts to build up its commercial cyber sector.

“A lot of people, Americans in particular, will think that the U.S., the U.K., France, Israel are more advanced than China when it comes to cyber power,” Eric Rosenbach, the Co-Director of Harvard’s Belfer Center, told CyberScoop. “Our study shows it’s just not the case and that China is very sophisticated and almost at a peer level with the U.S.”

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.

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.

China and the United States hold opposing beliefs about whether nuclear war can be avoided in a potential crisis or armed conflict. Taken together, these opposing beliefs increase the risk of nuclear escalation and can lead to greater crisis instability.

Domestic politics play a significant role in nuclear decisionmaking under two conditions: when uncertainty over the nature and intensity of a threat is high, and when leaders are incentivized to centralize nuclear policymaking.
