A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

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.

The Real-Life Events of "Oppenheimer"

| July 26, 2023

Christopher Nolan’s film Oppenheimer is outstanding. It’s an immersive biopic, the likes of which you will be hard to find elsewhere. The acting, cinematography, and seat-thundering sound, all combine to take audiences into the mind and moral decisions of J. Robert Oppenheimer, the man who led the team of brilliant scientists at Los Alamos, who built the world’s first atomic bomb.

How the Soviets Stole Nuclear Secrets and Targeted Oppenheimer, the 'Father of the Atomic Bomb'

| July 24, 2023

Calder Walton writes that Soviet espionage inside the Manhattan Project would change history. By the end of World War II, Stalin's spies had delivered the secrets of the atomic bomb to the Kremlin. This accelerated Moscow's bomb project. When the Soviets detonated their first atomic weapon in August 1949, it was a replica of the weapon built at Los Alamos and dropped by the Americans on Nagasaki.

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.
