North Korea: In Deterrence We Trust

Deterring North Korea is less risky than a preventative war.

Nuclear Policy

The Nuclear Policy Program aims to reduce the risk of nuclear war. Our experts diagnose acute risks stemming from technical and geopolitical developments, generate pragmatic solutions, and use our global network to advance risk-reduction policies. Our work covers deterrence, disarmament, arms control, nonproliferation, and nuclear energy.

War between the United States and North Korea has begun to seem like a real possibility. Within hours of the Sunday, September 3 test of what Pyongyang claimed was a thermonuclear weapon, President Donald Trump tweeted that the North Koreans “only understand one thing.” The next day, his ambassador to the United Nations, Nikki Haley, claimed that North Korea’s leader, Kim Jong-un, was “begging for war.” Then on Thursday, Trump described military action – using “new and beautiful equipment, the best in the world” – as “something certainly that could happen.”

The Trump administration seems to be considering military action because it appears to recognize that there is now little chance of denuclearizing North Korea and is concerned that “North Korea might not be able to be deterred.” But it is focused on the wrong question. The right question is not whether North Korea can be deterred, but rather how the risks of trying to do so compare to the risks of the alternative – a preventative war. When these risks are weighed up, deterrence turns out to be the less dangerous option.

Military action would run the risk of nuclear strikes against U.S. bases in South Korea, Japan, and Guam, as well as American cities. The U.S. intelligence community has reportedly assessed that North Korea is now capable of fitting a nuclear warhead onto a ballistic missile. Launching military action in the hope that Kim did not yet have a functioning nuclear arsenal would be insanity.

    Caught in the Middle: Chinese Biotech Firms’ Divergent Responses to U.S. Sanctions

    Chinese biotech companies have been on the receiving end of U.S. economic coercion. Yet their responses have differed significantly because firm and state interests are not uniformly aligned. For Washington, treating all Chinese tech firms the same, irrespective of their actual interests, risks pushing them farther into Beijing’s corner.
