By examining the alliance management of the US and China over two Koreas’ nuclear weapons programs, this dissertation finds the cause of nuclear restraint from security commitment. It asserts that a patron takes entrapment risk and increases security commitment when it fears nuclear proliferation greater than entrapment. This dissertation employs the combination of a case comparison method and a within-case method because nuclear restraint is a complex process that follows multiple steps, including rollback, suspension, or resumption of the nuclear weapons program.
From 1974 to 1982, the US provided South Korea with an increasing commitment level because Washington worried more about nuclear proliferation than entrapment. The US perceived high risk of nuclear proliferation, which might cause a major destabilizing effect in Asia, where Washington built a security network of bilateral alliances. To avoid nuclear proliferation, the US took entrapment risk and terminated South Korea’s nuclear weapons development.
In contrast, from 1993 to 2009, China provided North Korea with a decreasing commitment level because Beijing was more concerned with entrapment than nuclear proliferation. China perceived high risk of entrapment from a possible North Korean regime collapse and a massive refugee influx across the border. To avoid entrapment, China remained at a low commitment level to North Korea, which eventually conducted nuclear tests and withdrew from nuclear negotiations.
This finding expands our knowledge about the commitment by differentiating the risks of entrapment and nuclear proliferation. It also emphasizes the role of positive security commitment for nuclear restraint.
