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.

    The Unintended Consequences of German Deterrence

    Germany's sometimes ambiguous nuclear policy advocates nuclear weapons for deterrence purposes but at the same time adheres to non-proliferation. This dichotomy can turn into a formidable dilemma and increase proliferation pressures in Berlin once no nuclear protector is around anymore, a scenario that has become more realistic in recent years.

    Europe on Iran: Gone with the Wind

    Europe’s reaction to the war in Iran has been disunited and meek, a far cry from its previously leading role in diplomacy with Tehran. To avoid being condemned to the sidelines while escalation continues, Brussels needs to stand up for international law.

    Governing Aging Economies: South Korea and the Politics of Care, Safety, and Work

    South Korea’s rapid demographic transition previews governance challenges many advanced and middle-income economies will face. This paper argues that aging is not only a care issue but a structural governance challenge—reshaping welfare, productivity, and fiscal sustainability, and reorganizing responsibilities across the state, private sector, and society.

    Macron Makes France a Great Middle Power

    France has stopped clinging to notions of being a great power and is embracing the middle power moment. But Emmanuel Macron has his work cut out if he is to secure his country’s global standing before his term in office ends.
