Preserving the nuclear taboo after a nuclear first-use event: a nuclear ethical analysis

ABSTRACT According to Nina Tannenwald, the nuclear taboo is a deeply held moral norm against the first use of nuclear weapons. If the nuclear taboo is violated by a country engaging in nuclear first use, how might the taboo be preserved and nuclear restraint restored? An analysis contrasting the logic of nuclear deterrence with the logic of the nuclear taboo offers reasons why the nuclear taboo cannot be preserved if the response to nuclear first use is nuclear reprisal. Instead, the preservation of the nuclear taboo would require a combination of diplomatic, economic, and conventional military responses. Nuclear reprisal might restore nuclear deterrence, but it would also validate the role of nuclear weapons in national or alliance security policy. Taboo enforcement cannot rely on the very behaviors the taboo prohibits.
