International Security & Defense

Joseph  Nye writes that at a time when U.S. President Donald Trump has run through four national security advisers in four years and seems unable to distinguish national interest from his personal interest, Brent Scowcroft's legacy is more relevant than ever. He remains the model for a modern public servant.

The pandemic has pulled the future forward, forcing a changed perspective of national security, and now we must quickly adapt how we operate to reflect this reality, writes former Principal Deputy Director of National Intelligence Sue Gordon.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

Rebecca Davis Gibbons writes that having a full appreciation of the consequences of nuclear weapons and their place in society means learning from the stories of the survivors of Hiroshima and Nagasaki—but also from the stories from other survivors of nuclear explosions: those who lived and worked adjacent to testing sites in Algeria, French Polynesia, Australia, the United States, France, the Republic of the Marshall Islands, Western China, and Kazakhstan.

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

Joseph Nye writes that the world is increasingly obsessed with the ongoing power struggle between the United States and China. But the technology-driven shift of power away from states to transnational actors and global forces brings a new and unfamiliar complexity to global affairs.

In an interview with WIRED, former national intelligence official Sue Gordon discusses Russian election interference and other digital threats to democracy.

Combining decades of experience advancing frontier technologies, on the one hand, and analyzing national security decisionmaking, on the other, we have been collaborating over the past year in an effort to understand the national security implications of China’s great leap forward in artificial intelligence (AI). Our purpose in this essay is to sound an alarm over China’s rapid progress and the current prospect of it overtaking the United States in applying AI in the decade ahead; to explain why AI is for the autocracy led by the Chinese Communist Party (hereafter, the “Party”) an existential priority; to identify key unanswered questions about the dangers of an unconstrained AI arms race between the two digital superpowers; and to point to the reasons why we believe that this is a race the United States can and must win.

This paper has two primary objectives. First, it will support the argument that blast related TBI is uniquely different from the more recognized brain injury known as chronic traumatic encephalopathy (CTE) injury associated with impact trauma and therefore requires a different approach to both diagnosis and treatment. Second, it will provide recommendations for mitigating the effects of bTBI on the readiness and long-term health of special operators. 

Key recommendations will include identifying blast pressure thresholds, developing imaging technology, and blood markers to diagnose bTBI. It calls for the DoD to institute and sustain “baseline” health surveillance to detect patterns of injury and health distress early, promote awareness for the Center for Neuroscience and Regenerative Medicine Brain Donation Awareness Program, and to establish an active Cross-Functional Brain Consortium. An additional recommendation will include changes to training plans that continue to prepare operators for combat but reduce their exposure to blast trauma. 

The saber rattling from both Beijing and Washington has become strident, uncompromising, and seemingly unending.
