Nuclear Issues

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

In this episode of "Intelligence Matters," host Michael Morell speaks with former senior CIA operations officer and Moscow station chief Rolf Mowatt-Larssen about the likely trajectory of the war in Ukraine, including the possibility of a negotiated peace — or dangerous escalation. Mowatt-Larssen offers insights on Putin's options, potential rifts among his intelligence agencies, and persistent rumors about the Russian leader's health. Morell and Mowatt-Larssen also discuss Western involvement in the conflict and the lingering potential for the Kremlin to use weapons of mass destruction. 

Whether they regard it as competitive, cooperative, or confrontational, virtually all observers agree that the U.S.-China relationship is consequential. From cyber norms and AI to military tensions in the Taiwan Strait and the global struggle to turn the tide on climate change, how Washington and Beijing manage their shared future will shape the globe for decades to come. Through research and relationship-building, the Center is dedicated to helping the U.S. and China collaborate and compete without conflict.

This report examines the role the intelligence community has played in U.S. efforts to deal with North Korea since the beginning of the Cold War.

Calder Walton writes that autocratic regimes — China, Russia and Iran — have been using social media to try to influence U.S. public opinion. History reveals how and why a one-party regime used disinformation to salvage its reputation following a disaster — the Soviet Union's 1986 Chernobyl nuclear catastrophe, whose history also reveals how such disinformation can be countered.

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.

Joseph Nye writes that some decoupling of interdependence is likely, particularly in areas related to technology that directly affect national security. But will Washington and Beijing go too far?

It seems unlikely that Russia will again possess the resources to balance U.S. power in the same way that the Soviet Union did during the four decades after World War II. But declining powers merit as much diplomatic attention as rising ones do. Joseph S. Nye worries that the United States lacks a strategy to prevent Russia from becoming an international spoiler.

The competition between the United States and China will decide the continent's fate—and one of them has a head start.

In mid-January, a team of scholars from the Belfer Center’s Intelligence and Managing the Atom Projects traveled to Tel Aviv, Israel to examine samples of, and receive briefings on, an archive of documents related to Iran’s nuclear weapons program. The large cache includes some 55,000 pages of documents and a further 55,000 files on CDs that included photos and videos. A clandestine Israeli intelligence operation spirited the materials out of Iran in early 2018.

The documents that the Belfer group were shown confirm that senior Iranian officials had decided in the late 1990s to actually manufacture nuclear weapons and carry out an underground nuclear test; that Iran’s program to do so made more technical progress than had previously been understood; and that Iran had help from quite a number of foreign scientists, and access to several foreign nuclear weapon designs. The archive also leaves open a wide range of questions, including what plan, if any, Iran has had with respect to nuclear weapons in the nearly 16 years since Iran’s government ordered a halt to most of the program in late 2003. 

This brief report summarizes the group’s conclusions about what the archive reveals about Iran’s program and questions that remain open.
