Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

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.

On 9 March, India accidentally fired a BrahMos supersonic cruise missile into Pakistan. On 11 March, an official Indian statement on the incident acknowledged that “in the course of a routine maintenance, a technical malfunction led to the accidental firing of a missile.” Pakistan, in a press conference on 10 March, had already declared that a “high-speed flying object” from India had entered Pakistani territory. General commentary has criticized India’s sluggish communications in the immediate aftermath of the accident. This article puts Indian messaging around the misfiring to three tests of communication: language, timeliness, and narrative control.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles.

The World’s host Marco Werman speaks with Nicholas Burns, a former US under secretary of state for political affairs and a former ambassador to NATO.

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

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.
