That nuclear weapons haven’t been used in a military conflict since 1945, is one of the most intriguing research puzzles in the field of International Relations.

 Specifically, the main aim of this research endeavor is to enrich the existing scholarship on the nuclear “taboo” through innovative cross-national and multi-dimensional approaches to this phenomenon.
